How to Break/Resize/Install a Master Link on a Motorcycle Chain

A 2007 Ninja 650R with its pants down (chain and front sprocket cover removed)

If you’ve never done chains and sprockets on a motorcycle before, there is more to them than what you’ve done with a bicycle chain.  Being an open part of the drive system, they offer a relatively easy way to modify your bike’s performance.  With smaller (faster) sprockets you can produce a revvier, shorter geared engine.  With a shorter chain you can close up your wheel-base creating a bike more willing to change direction.  Chains and sprockets are a bike fettler’s delight.

On top of sprockets, you also have a pile of chain choices.  O-ring chains are the cheaper, lower efficiency alternative, while X-ring chains offer more efficiency and less maintenance at a higher cost.  They also come in a rainbow of colours and a variety of sizes from little dirt bikes all the way up to thousand plus cc super-bikes.  


Chain sizes and dimensions
From little dirt bikes to bike motors.

Chain sizing is based on the width of the chain and the length between the pins in the chain.  You’ve got match all these up with the right sprockets or it won’t all fit together.  With so many factors in play, it pays to get a handle on chain mechanics before you take a run at changing the chain on your motorbike.

Here’s a primer on how to break a chain.  Some people say cutting a chain but you aren’t cutting it, you’re breaking it by popping the rivet out and dismantling the chain links.


How to Break a Chain:

  • If you’re removing your old bike chain, find the master link (it should be the one that’s different from all the rest)
  • Put a chain breaking tool on the chain and push the rivets out – do a bit on each side at a time until the chain ‘breaks’ open.  I did this with a bicycle chain breaker (see bottom) and it worked fine.
  • Once you’ve ‘broken’ apart the master link the chain will come apart and you can pull it through and free of the bike.

To reduce chain size on a motorcycle:

  • if you have a 520 or smaller chain and a good motorcycle specific chain link breaking tool you can simply push the rivet through (see the video at the bottom)
  • if you don’t have specific tools, grind or file down the rivet and then tap it out with a hammer and punch pin.  If you grind down the rivet you can also use a bicycle weight chain breaker (see a pic at the bottom) to push out the worn down rivet.
  • triple check which link you want to pull and use something like Gearing Commander to make sure you’ve got the right number of links in your chain.  (This is what I’m kicking myself for not doing).
  • Using the bicycle chain puller on filed down pins, I pushed on side and then the other and then repeated the process and the rivet popped loose along with the outer chain links.  Since you’re only filing down the outer link (which you’ll chuck after) it doesn’t matter if you file into it a bit.
  • With the chain dismantled you should now have two inner links ready for a new master link.
Installing a New Master Link:

  • Install the little rubber washers on the master link rivets and slide it onto the chain – do this on the sprockets as it’s easier to do with some tension on the chain.
  • put the last two rubber washers on and the end plate and then use the chain tool or some other kind of clamp to press the side plate on.
  • if you’ve got a rivet type master link you need a light hand and some patience to press in the rivet ends.  If you’re too heavy handed you’ll bind the chain and swear a lot.
  • The more traditional type of master link is the kind I was familiar with from bicycles.  It comes with a slid on clip.
Don’t freak out if you’ve got the rivet type master link, just make sure you have the right tool handy.  The rivet type link is very strong and performs pretty much like all the other links if installed properly, which is why you’ll find it exclusively on high performance chains.  Check out the youtube video at the bottom for a good primer on how to do this.
 
If you take your time and work through it slowly, you’ll have a new chain on in no time.  If you want to get into sprockets the rears are remarkably easy to do.  When you remove the rear wheel bolt the wheel drops down and the floating rear caliper on the Ninja 650r simply disengaged and I hung it on the frame.  You can then remove the wheel.  The rear sprocket is held on with your typical nuts and was easy to swap out.
 
This front sprocket is a f&#*er.
The front sprocket was in good shape, so I gave up on it.  Others online have said that they are pretty straightforward if you have an air gun, but even with a breaker bar I couldn’t budge the damn thing and I can pick up a car by the fender.  You remove the front sprocket by bending back the holding washer, putting the bike in gear, stepping on the rear break to hold everything still and removing the nut (it’s a good fit on a big 27mm bit).  If there’s a trick to this (other than getting a compressor, air tank and air tools), I’d love to hear it.

Follow up with Chain And No Agony for how easily the new chain went on with the right tools.

 

 

 

 

If you’ve only got a bicycle chain
breaker, file or grind down the rivets
first before you push them out.

If you’ve broken bicycle chains before you know the basics.  Motorcycle chains are much heavier duty so the process requires stronger tools capable of dealing with stronger rivets.  If you have a bicycle chain breaker you just have to take your time and file down the rivet you’re going to push through first.  It took me a couple of minutes of filing to do this.  Lazy people on the internet say buy a Dremel.  If you’re lazy, that’s what you should do.

Mostly Ironheads

The Connie is off getting safetied, and the Ninja has found a new home.  I’m bikeless!

One of the things you learn about motorcycle culture is that it tends to exist underground, out of sight.  For example, this week I discovered that there is a bike shop in the small town that I’ve lived in for five years.  I had no idea that down the back of the industrial mall behind the country market is a specialist motorbike shop.  This reminded me of our trip to Old Vintage Cranks a couple of summers ago.

I’d contacted the owner, Lloyd, over the phone during the week about getting the Concours safetied.  He doesn’t usually work with ‘metric bikes’, but he was willing to look after me.  Mostly Ironheads is a full service shop that, in addition to offering everything you need to maintain your bike, also offers you some genuine historical motorcycling perspective.  While chatting with Lloyd he showed me a 1934 Harley Flathead engine that he was in the process of rebuilding.  In the front of the shop you’ll also find a collection of customized Harleys from various decades.  I’m going to bring the 3d-scanner when I return for the Connie next week and get some models of this classic American iron.

It’s convenient to wander around department store styled dealerships and bike shops, but it isn’t all that interesting beyond what you’re shopping for.  Places like Mostly Ironheads run at a different speed.  The proprietors are always happy to spend some time chatting with you and the chances of seeing something genuine and learning something about motorbiking are much higher.

If you’re travelling through Elora, Ontario on two wheels (and many people do to have lunch by the river in the summer), be sure to pop down behind Dar’s Country Market to Mostly Ironheads and have a look at a hidden piece of Ontario motorcycle culture.

Vanmageddon: It must be February

It’s getting to be that time of year again – months of snow bound Ragnarok motorbike hibernation are making me twitchy.  I like winter generally, it offers a very different and sometimes beautiful view of the world, but when motorcycling has become your go-to stress reliever, being out of the saddle for months is a source of pressure.  If you look at the seasonal leanings of this blog, you’ll see winter generally leads to yearning.

This time around the fixation is on the Mercedes Metris Van.  I’ve previously looked at Ford Transits from a Guy Martin point of view, and other small van options for moving bikes to where I can use them.  The Metris has the benefit of being as efficient as the little vans but can swallow the Tiger with room to spare.  The other little vans would required a tight squeeze if it’d fit at all.



Another benefit of the Metris is that you can customize it to your needs and it’ll still go everywhere a normal vehicle will.  It’s also surprisingly competitive in price to the Ford and Dodge/Fiat options.  So, what would I do with the only Mercedes I’ve ever been interested in buying?

Last year at pretty much this exact same time I was mapping out waterfalls in Virginia.  The drive down to Roanoke is about 11 hours.  With the Tiger in the back I’d have left right after work and been in Roanoke by midnight.  After a good sleep and breakfast and I’d be out all weekend making use of those lovely temperatures while chasing spring powered waterfalls across the Appalachians.  After a good ride Sunday I’d have a big dinner then head back into the frozen wastelands of the north getting in after mid-night, but I’d have the Monday of the long weekend to get back on it again.


All told that’d be about 2000kms in the van and another six hundred or so miles riding in the spring blooming mountains.  If I could convince the family to come along, they could crash in the hotel or jump on the back and come along.

I’ve been reading Guy Martin’s autobiography and his van powered wandering to motorcycling events all over the UK and Europe seem entirely doable, if you only have that van.  He seems to be able to fit an improbably amount into a very limited amount of time simple by getting himself there and then getting himself home again.


It’s a good read that trips right along.  I enjoyed the narrative flow of the follow up book When You Dead You Dead more (I read it first), but you quickly fall into Guy-speak and feel like you’re sitting in a pub with him hearing the tale.  If you like motorcycles and racing it’s brilliant.  If you just like a good story well told, it’ll do that too.

Triumph Tiger History

First gen Tiger from the late ’30s

I’ve been finding out the history of Triumph Tigers from various places on the interwebs. The first Tigers were born just before World War 2 and were quickly put on hold when the war started. With rigid rear frames and girder front suspensions, these were 1930s bikes in every sense.

Tigers followed the steady evolution in motorbike technology throughout the Twentieth Century, and also followed some rather silly styling trends, like shrouding the mechanicals in 1950s aero inspired nonsense.

’69 Tiger made in the UK the same
year I was!  Nice high pipes!


Things get interesting again in the 1960s, with late ’60s Tigers, along with the British motorcycle industry in general reaching a zenith before being crushed by their own weight and a lithe, hungry wave of Japanese imports.

Pam Anderson riding
a Tiger!

Through the long, dark tea time of the soul in the ’70s and ’80s (and while my parents and thousands of others fled the country) Triumph went down in flames along with much of British manufacturing.  In ’83 John Bloor, a building contractor who was looking into the purchase of the derelict Triumph factory to build more homes ended up buying the brand.  After sitting on it for a while he rebooted it and built a new factory.  

It’s one of the best examples of British manufacturing rising out of the ashes of old money and old ideas and embracing a more effective approach to manufacturing.  Without the conservative  establishments of aristocratic ownership and unionized labour Bloor was able to reignite British engineering and give it chance to shine again.  You might think that it isn’t properly British if it isn’t mired in limited social mobility and the kind of Kafka-esque bureaucracy that makes building something well next to impossible, but that was only a moment in Twentieth Century British history and doesn’t speak to the engineering prowess of our little island.


After Triumph rebooted in the early ’90s, the Tiger reappeared in ’93 during the second wave of model introductions.  An early example of what came to be known as adventure bikes, the Tiger was a tall, long suspension, multi-purpose machine running a three cylinder engine.  

Having tapped into this trend while it was still only popular in continental Europe, Triumph’s Tiger line has been a key part of their brand for the past twenty plus years.  If asked what bike I’d want to take around the world tomorrow, the Tiger Explorer is at the top of the list.

Tigers have been around, in one form or another, since before World War Two.  I’m looking forward to getting to know the one I found this month.

Track Day Planning

I’m pretty keen to go do a track day, and I have a buddy who is the same.  The Grand Bend Motorplex does motorcycle open lapping on its track.   I found GBM through motorcycletrackdays.ca.  The upcoming SOAR racing event at Grand Bend offers open motorcycle lapping prior to their weekend events.  That might be a good time for two nØØbs to go as there will be experienced track day people on hand to help us fumble through the technical inspection.

I figured it would be a show up on what you rode here on and go on the track, as you would with a car, but bikes seem a bit more involved.  Here is the list of motorcycle specific technical requirements:

  • Is your kickstand secured? Your spring return isn’t enough on a racetrack. Use a plastic strap tie or duct tape to secure your kickstand in the up and locked position before you come to tech. 
  • Tape over your speedometer. It’s the rule.
  • Make sure your throttle returns quickly and positively. We want to see it snap back when you release the grip. 
  • Change your antifreeze for straight water. If your bike puts antifreeze on the surface, it shuts the entire track down and may result in suspension. Antifreeze is 100 times worse than water on asphalt (It’s like wet ice). Swap it out for water before you proceed to tech. 
  • Tape over or remove lights, signal and mirrors. They all shatter and they all puncture tires. 
  • Brakes: Make sure they’re properly functioning, front and back, with no leaks, because we’ll check. 
  • Chain: Check your drivechain adjustment. Too tight or too loose means breakage. Refer to manufacturer’s specification. Also, check your master link. A rivet style link is preferred, but a standard ‘slip on’ while suffice if you put a dab of silicone on the key to secure it. 
  • Now that you’ve ensured your brake lines don’t leak, check the rest of the bike. Your engine and suspension components must also be leak free. 
  • Overall track worthiness: These are the small things that can lead to disaster. Loose lines can snag. If it can flop around, it can be snagged and lead to a crash. 
  • Body: All body parts must be secured or removed. 
  • Mechanical: Check your fasteners and ensure they’re secured at recommended torque. 
  • Tires: Properly inflated, with structural integrity intact (sidewall, tread, steel-belts, bulges).
Most of that is common sense/maintenance, but there are a couple of bits that will require some thought.  Tying up the kickstand is all well and good, but that means you’re bringing a rear stand to keep the bike upright.  Swapping out the antifreeze also means you need to bring some distilled water.  Some tools, disposable gloves and fluids would probably be a good idea too.  Suddenly the back of the bike I want to ride to the track day is looking like a hardware store.  You wouldn’t want to ride an hour and a half to a track to find out you don’t have what you need to go around it.  Short of asking for a pit crew to accompany you in a four wheeler, riding solo to a track day seems difficult if not impossible.
Of course, this leads you down the road to a trailer, which then begs the question, why use your road bike for track days when you can pick up an older sport bike for not much, not have to pay for road insurance on it and spec it out specifically for track days.  Stripped of lights and needless accessories like rear foot pegs and indicators, you’d be ready to ride as soon as you roll it off the trailer, and the machine would be tailored for the track.
I’ve been to several racing schools, but the one time I really got into it was while living in Akita, Japan.  Kyowa Race track was a small carting track deep in the mountains south east of the city.  Kazutoyo, a student of mine, was an avid racer (he came to Canada for a summer to participate in a Mosport racing mechanics program).  We’d go up there half a dozen times in the summer and spend the day hauling the carts around that bendy circuit as quickly as we could.
The vehicle of choice for the carts and the paraphernalia that went with them was a cargo van.  We’d be able to fit three people, the tools, the disassembled cart and spare tires and other odds and ends all in the van and head to the track.  Riding around at break neck speeds was awesome, but I have fond memories of all the fettling that when on in the pits too; it’s all part of the race experience.
 
Ford Canada’s handy Transit Van Builder got me all set with a customized utility van that could carry two bikes and gear with ease… things I’d do if I were rich!

Now that I’m thinking about doing a track day on two wheels I’m tempted to imitate those Japanese carting guys and get what I need to make a track day possible.  I’ve been wishing for a trailer several times this summer to haul lumber.  Having one on hand and a vehicle to haul it would be handy for more than just track days.  

Or just win the lottery and get the full on racing support van.

If Mechanical Sympathy were to go full on into racing, I’d grab that 1000cc VFR from Angus (in my Transit race van) and prep it for racing.  Stripping off all the lights and extras and minimizing it down to a race bike.  I’d be a dangerous man if I had more money.

In the meantime I’m still trying to look for ways to ride my Ninja to the track and do some laps without dragging along someone in a cage to support the activity.

Around The Bay: Part 2, an Informed ride

Putting on the miles and building muscle memory.

A couple of recent articles informed my circumnavigation of Georgian Bay.

Bike magazine’s resident lawyer had a great piece on the dangers of the over educated novice rider.  He made the poignant observation that people who haven’t had a lot of seat time but have over-thought riding to the nth degree often have much nastier crashes than less trained but more experienced riders.  Sometimes the best thing to do is instinctively grab as much brake as you can instead of overthinking an impending disaster.  Perhaps riding is more of an art than a science, informed by experience, not training.

As a teacher I found this critical assessment of instruction over experience to be both interesting and probably accurate.  There is a lot of anxiety over motorcycle riding from the general public  I was determined to get some saddle time and learn the hard way rather than in theory.  The over-focus on training and gear tries to mitigate this fear, and it helps to a degree, but if fear is what drives you, I’d suggest that motorcycling isn’t what you should be doing.

The second piece was Neil Graham’s editorial in this month’s Cycle Canada.  Neil is getting back to form after an agonizing winter back injury.  After everyone else had moved on Neil stayed out on track until it became kind of boring and he relaxed into the ride.  In his case it was track riding on the edge, but it still spoke to the teaching of muscle memory, something that became evident in the previous Bike piece as well.

On my way out of Southern Ontario I was intentionally trying to untense muscles, especially the ones I subconsciously tense when I’m riding.  Yoga probably helps with this, but I was able to sense and untense muscles in my legs and backside while riding.  Being loose and heavy on the bike allowed me to ride further without fatigue.  It also allowed me to respond to issues quickly and lightly.  Being able to free your mind from the demands of your body and put yourself into a state of relaxation also opens up a state of heightened awareness.

Riding into my driveway on Sunday afternoon I was exhausted but elated and felt like I was coming out of some deep meditation.  My mind was full of the 900 kms I’d seen, smelled and felt, and the soreness became something that I’d worked through; the second wind was a real endorphin rush.  After the three hundred plus kilometre stretch down the backside of Georgian Bay I suddenly found myself operating beyond the soreness of the long ride.  Coming off the very demanding highway ride to quiet back roads probably helped too.

If you’re able to find a state of intense focus while performing a strenuous mental and physical activity like riding a motorcycle, you tend to be able to find that state much more easily when you’re not on the bike and things are easier.  Being able to focus and perform while under duress makes entering that state of intense awareness in other circumstances that much easier.

I guess I found that moment beyond the thinking and training where I relaxed into the saddle and became the ride.  If long distance riding can do that, I suspect I’m eventually going to want to do the deed and get my iron butt.

Any Day on Two Wheels is a Good Day

Almost three hours into an interminable visit to the local walk-in clinic last Friday night I’m told that I’m over a hundred degrees, in terrible shape, but it’s just a virus and I have to suffer through it.  I should go home, rest and feel better, except I can’t because this is the Haliburton Birthday Weekend.  We’re on the hook for a hotel that won’t cancel a long weekend booking, even under a doctor’s advice.

I go home, sleep poorly and take lots of pills.  The next morning I’m shaky and either sweating or freezing cold, so a perfect day to go for a three hundred plus kilometer ride across the province.  The original plan was to leave early and take my time picking off must-ride roads in the south end of the Haliburton Highlands before finally arriving at our hotel near the town of Haliburton.  That didn’t happen.  Instead, I followed my wife and son in the car on the shortest possible route.  We stopped frequently and a sunny, relatively warm day meant it wasn’t as miserable as it could have been.  We all fell into our room after five o’clock and collapsed.

I could have driven up in the car, but the whole point of the weekend was to ride the Highlands, so bike it was.  Sunday morning dawned overcast with heavy clouds.  The rain held off until I saddled up after a late but brilliant breakfast at the Mill Pond in Canarvon.  I was doped up on fever and flu medication and as good as I was going to get.  The plan was to wind up Highway 35 to 60 and then into Algonquin Park.  If the weather was atrocious or I fell apart physically I could always turn around, but if I’m going to do it, I’m going to do it; turning around isn’t in my nature.

I’d originally planned to stop often and use the new camera, but needs must and I was on a mission to complete that fucking loop.  The backup plan was to use the Ricoh Theta 360 camera on the fly.  It’s a push button affair that is easier to use than a satnav.  Hit power, press the shutter button, put it away.  The tank bag that came with the Tiger has a handy little pouch at the front that fits the camera perfectly.  I’d never tried using the Ricoh by hand like that before, but it seemed like a good idea when my time on task was at a premium.  Since it takes in everything at once you don’t need to worry about aiming or focusing it either.


Heading north out of Canarvon the rain closed in immediately.   On the upside, it was chasing away a lot of the holiday traffic, though this is Canada, so what you’re looking at above was pretty typical for this ride… on a long weekend.

Highway 35 dodges and weaves around lakes and Canadian shield as it works its way up to meet 60.  If you’re not blasting through the dynamited, rocky skeleton of Canadian Shield, you’re winding your way around muskeg, never ending trees or scenic lake shores.  And it does all of this while being a bendy roller-coaster of a road.

The gas station in Canarvon was shut down, so I suddenly found myself running onto empty as I powered north into the big Canadian empty.  Fortunately, I came across a Shell station at the intersection with 60 and filled up.


By that point the rain was more steady than not, so I stepped into the rain suit and wove my way into Algonquin Park.  Suddenly the roads were full of people with GTA tagged SUVs all driving around aimlessly looking confounded by all the trees.  Throughout the entire loop Algonquin was the only time I was stuck in traffic.  I pulled in to the Visitor’s Centre and had a coffee, stretched my legs and soaked up the ambience.  The lady at the counter was nice enough to give me ten cents off on my coffee because I didn’t have change.


Fifteen minutes of crying babies and screaming kids and I was longing for the wind and silence of the road again.  The Visitor’s Centre was near the half way point in the loop, and with a coffee in me (my first caffeine in days) I was ready to go all the way.  The weather was occasional spotty rain, so it wasn’t as terrible as it could have been.  I was warm and dry in the rain suit and the drugs had beaten back the fever, so on I went.


I’d never been out the East Gate though I’ve been to Algonquin since I was a relatively new, ten year old immigrant to Canada.  It feels older than the West Gate, looking more like a toll booth than an art deco entrance to one of the biggest and most famous parks in the country.  Once out of the park traffic evaporated and I was once again alone in the woods.   I’d originally planned to head all the way over to the 503 for a wiggly ride south, but 127 cut off some kilometers and I was already feeling the hours in the saddle.  It was an empty trek down the 127 to Maynooth, albeit with some pretty scenery.


The rain came and went and I got so used to riding on twisty roads that it became second nature.  What would have been a ride to road where I live was just another road in Haliburton.  The Tiger spent very little time on the crown of its new Michelins.  I pulled up in Maynooth for a stretch before starting the final leg of the loop back over to Haliburton Village.


Strangely, and for the first time since the trip began, the roads dried up and the sun started poking through.  Up until now I’d been on local highways; fast, sweeping roads that, while curvy, were designed for higher speeds.  Out of Maynooth I took Peterson Road and got to enjoy my first local road with lots of technical, tight radius turns and elevation changes.  Peterson and Elephant Lake Roads were dry and a lovely change from the wet highways I’d been on before.

On a short straight between the twists on Peterson Road out of Maynooth.
Those 41 winding kilometres to Pusey flash past in no time!

The local traffic was apparently very familiar with bikers making time through the area with several trucks pulling over and waving me through; some country hospitality on a long ride.  

The pavement continued to dry and the Tiger got friskier and friskier as I rode on to Pusey and then Wilberforce.  I was lucky to see another vehicle in either direction on this busy long weekend – just my kind of road trip.  No matter how sick I’m feeling there is nothing like a winding road and a motorbike to put a spring in my step.  For the first time on this ride I wasn’t carefully monitoring my health and the weather, I was just enjoying being out in the world on two wheels.


The sun battled with clouds all the way under Algonquin Park and I soon found myself lining up for an approach back toward Haliburton, this time from the east.  Once again I elected to cut some extra miles out, forgoing a ride to Gooderham for the joys of the 118.



Swooping through the lake of the woods while leaning the ever eager Tiger around lakes, trees and rocky outcroppings had me in nirvana; it was like riding through a Group of Seven painting.  

 

By this point the drugs were wearing off, I’m starting to wilt and the deed is almost done.  The last few miles into Haliburton turn ominous as dark clouds fill the horizon and  the temperature drops.  I steel myself for the final push.
 

 

 
As the sky fills in and the rain starts to fall again, my goal is in sight.  I pass through the small town of Haliburton like a ghost and pull up just as house keeping has cleaned our room (the family is out at the pool).  Ten minutes later I’ve taken another round of drugs and I’m in a whirlpool tub getting the heat back into me.
 
The logic I followed doing this was:  any day on a motorcycle is a good day.  Even with a fever and a nasty virus I had a great ride and a real sense of satisfaction in completing my birthday loop of the Haliburton Highlands.  It would have been nice to do it without feeling like I’d been turned inside out, but hey, any day on a motorcycle is a good day.
 
 
The ride:  a 270 km loop through Algonquin Park and back around to the town of Haliburton.  All told I was on the road for about four and half hours, including a gas stop, a coffee at the Algonquin Visitor’s Centre and a leg stretch in Maynooth.

 

The camera: a Ricoh Theta SC.  It takes two hemispherical photos in both directions and then stitches them together, which makes the camera disappear in any photos it takes – which is pretty freaky.  


Having all hardware buttons, you don’t have to futz around with a smartphone to interface with it like you do with the Fly360.  As a camera to use while photographing a motorcycle ride it doesn’t come much easier than this.  It’ll do video and save it in 360 format so you can look around in the video on a smartphone.  It does the same thing with photos.  


The photos in this piece were opened in the Ricoh software and then screen captured.  That’s how I cropped images to show various things.   The original, unedited photos are pretty funky (see below), but look good with some judicious cropping.





Where we stayed:  The Pinestone Resort just south of Haliburton.  The prices are reasonable and you get a nice room.  The facilities are good with golf on site (if you care about that sort of thing) and a salt water pool and sauna.  The onsite restaurant had us waiting 90 minutes (in my case for a French onion soup and salad) and isn’t cheap.  Eating elsewhere might be a good idea, especially on a busy weekend, but anything else is at least a ten minute drive away in town.  We stayed there last summer on our ride back from The Thousand Islands and it was good – they seemed to have trouble handling the traffic on a long weekend this time around though.

Motorcycle Handling & Chassis Design

Tony Foale’s brilliant engineering manual, Motorcycle Handling & Chassis Design, gives you an inside, technical look at how motorbikes operate.  It also gives you some idea of just how precarious the act of piloting a motorcycle is.  Much is said about how free people feel when riding and the physics behind flying on two wheels makes it that much more magical.
 
That first time you roll on the throttle and your feet leave the ground not to come back down again for miles, you get that sensation of flight.  Your senses are alive on a motorbike as the world makes itself felt in many different ways.
 
The naked exposure you feel when riding is obvious.  What is less obvious are the hidden forces at work that allow you to do crazy things like hang sideways while cornering.
Anyone who has seen a racing motorcycle suddenly hit the ground can speak to how suddenly these balancing forces can fall out of sync.  Foale’s book is full of helpful diagrams that clarify some pretty arcane physics.


Cornering on a bike is one of the most complex and misunderstood aspects of riding.  Keith Code does a good job of explaining this in Twist of the Wrist.  Foale’s approach is more interested in the mechanics of the machine and how it handles the forces working on it.


From a rider’s perspective, corning is a balancing act, but from the suspension’s perspective things get a lot heavier when you’re bending into a corner.

 

Compared to a car, motorcycles have very different dynamics that often surprise riders when they are testing the extremes of two wheeled dynamics.  Reading Foale’s book (though he pitches pretty hard) is worth it even if you’re only getting a sense of just how differently the ‘integrated system’ that is a motorcycle works.

Foale also gets into the geometry of the motorcycle.  From wheelbase and centre of gravity to more complex issues like how suspension height changes those fundamental forces.  Of course, in a corner a the suspension is severely compressed, changing the bike’s responses in dramatic ways.  You get a real sense of how connected and complicated the physics of riding is after reading this book.
 
The copy I read was the 2002 version, but he still managed to work some of the newer computer based analysis of motorcycle physics.  Static pressure and its role on aerodynamics is a relatively new aspect of motorcycle theory, but Foale covers it.

You can find the latest version of this technical manual online from Foale’s website, but you can get a good idea of what it’s all about from Google Books.  I’m curious enough about changes and updates that I think I’m going to spring for the new PDF ebook.


 

Expensive Aerodynamic Games

Those people paid to watch very highly paid drivers parade
around lap after lap and throw fits if anyone upsets the tedium.

I just watched the Spanish Formula One Grand Prix.  I used to be a huge Schumie fan and watched F1 religiously, but I’ve wandered away since I starting two wheeling.  It was an historic race with Max Verstappen being the first Dutch driver and youngest ever driver to win a GP race, but it was tedious.  Sky Sports’ announcers tried to rev it up with one of the few attempted passes, which was then followed up by Sebastien Vettel complaining about an attempted pass.  Daniel Ricardo, the driver who attempted the pass said after the race, “I know no one tries to pass any more in Formula One, but I did, and it didn’t work.”

When you’re working the air around a car that hard,you make
a lot of turbulence, which makes it hard to pass.  If you clip
another car with wings on it like this, you’ve probably just
done a million dollars in carbon fibre damage.  No wonder

they all drive around worried at being passed.

Having not seen a grand prix in a few years, I was surprised at how complex the wings have become.  The new normal isn’t a front chin wing and a rear spoiler, it’s layers upon layers of carbon fibre.  Thanks to complex 3d modelling the wings now consider wind flowing over them in all dimensions, so the wings have become these origami type pieces of industrial art.  You can only imagine what it costs when one gets clipped by a wheel.

The upside of all this aerodynamic black magic are cars that can corner like they’re on rails because they have tons of carefully managed air pushing them into the pavement.  The downside is all that down-force creates huge turbulence, making passing next to impossible.  MotoGP doesn’t produce passing stats, but based on any criteria I can imagine passing is orders of magnitude greater in MotoGP.

MotoGP has played with aerodynamics before, but because motorcycles change their angle of attack (they lean) when they corner, it isn’t a relatively static shape that is always facing the oncoming wind blast.  As a result the benefits of consistent down-force while cornering aren’t there for motorbike wings, but that isn’t stopping MotoGP from pushing deep into it this season.

The vestigial wings on MotoGP bikes don’t do much to glue the bike to the ground in corners (the main purpose of F1 wings), but they do provide some stability while under acceleration (keeping the front wheel from rising).  Turning a wing sideways makes it fairly useless, so acceleration is the only place it’s facing the wind properly.  Even with these modest wings, riders are complaining that the amount of turbulence coming off machines has increased, making passing more difficult.  Between that and worries about wings clipping people in an off, there are obvious dynamic concerns around winglets.

Another problem with aerodynamics is that they’re incredibly expensive.  You can only go so far with computer simulations before you wind up in a wind tunnel testing your designs, and wind tunnels aren’t cheap.  Developing aerodynamics mean many models and constant refinement.  That the end results aren’t that significant begs the question: why do it?

What I’d like to see is MotoGP ban wings.  The aerodynamic costs limit other manufacturers from considering entering the fray.  A strong multi-manufacturer competition is a big part of MotoGP’s success.  That they create turbulence that makes following bikes unstable at speed and reduce chances of passing is another strike against them.  The aesthetic argument that they turn the simplistically elegant racing motorbike into a warty toad also rings true; winglets aren’t pretty.

I love the high tech nature of Formula1, but aerodynamics have made the cars fantastically expensive with no real benefit beyond the race track.  Improvements to engines, transmissions and safety have a clear connection to the evolution of automobiles in general, but massive wings and tons of down force don’t.  Watching a film like Rush reminds me of a time when drivers drove.  Today’s races are more like a Moon shot, and the drivers astronauts.  In the last race Hamilton couldn’t compete because he couldn’t get his car to reboot, and Vettel is probably still upset that his carbon fibre wings might have been touched.  If I wanted to watch people who can’t work computers I’d go to work, I hardly want to watch it in an F1 race.  If I wanted to watch people worried about how perfect their cars looked, I’d go to a concour d’elegance.

A Formula 1 with physically smaller cars and reasonable down-force limits could still explore the technical boundaries of driving on four wheels while encouraging something that looks less like a parade lap and more like racing.  Without the wings dripping off them and huge turbulence, passing could become a part of an F1 race again, perhaps so much so that drivers don’t complain about a single attempted pass.  If F1 wanted to explore a more functional aspect of aerodynamics they should limit the massive wings but allow small, adaptive aerodynamics.  That’s something that would once again be relevant to the evolution of the automobile.


I can only hope MotoGP doesn’t follow F1 down this evolutionary dead end of aerodynamic inflation.  A bike festooned with wings wouldn’t just be ugly, it would be irrelevant.

Can you imagine if the wings knocked each other, or got locked together?  I like my bike racing frenetic, fast and side by side.

 

Four abreast heading into the first corner?  The beginning of another frantic pass-fest in MotoGP.
