Motorcycle Mass and the new CCM GP450

So, there is a new British adventure motorcycle, just starting production for Europe, and hopefully coming to the US someday.  The company is CCM for Clews Competition Motorcycles and, since they came out of motocross, they emphasize light weight.  I think they have a great idea and I truely hope that they can make it to the US market.

Most of the pictures here come from a review article by Nathan on Adventure Bike Rider.  Here is the link to their review.

What do I mean by a light weight motorcycle?  Their GP450 Adventure is claimed to have a weight of just over 300 pounds full of fuel.  And this isn't some small motocross fuel tank but a reasonable 4.5 US gallons which should give 225 mile range at 50 mpg.  50 mpg is what I get out of my KLR, as long as I stay off the slab.  The CCM has a more modern, fuel injected engine of equal horsepower but lower displacement.  I'm guessing that it will get better fuel economy than the KLR and very acceptable range on a tank of fuel.

What's the advantage of light weight?  To me, lighter weight makes everything better.  Acceleration, braking, cornering, all improved.  My ability to get the motorcycle to respond quickly, improved.  Fuel economy, improved.  Overall, I would rather have a lighter bike than one with more horsepower.

Among all the rest of the reasons, the GP450 is a nice looking bike with premium components and a size that fits even me (at least according to

The GP450's light weight got me to thinking.  How light are other motorcycles that I either like or have tried (and fit?)?  What is their weight and how is their weight/power ratio as an indicator of acceleration performance?  Now my trusty old KLR is a bike that I have ridden for over 10 years.  It has enough power for me and is a good fit.  Anything on this list that improves on it's weight or weight/power ratio is going to be just fine.

The KTM 640 LC4 Adventure is an old bike in the Rally Raid style with excellent fuel range.  I have always found KTM bikes to be lighter than most.  The KTM Duke 690 is basically a hooligan thumper.  The KTM Duke 390 is new for 2015 and is a lighter, short range bike like it's bigger brother, the 690.  As you can see, the 640 Adventure, the new Duke 390, and the CCM are all about 12 pounds/HP with a 200 # rider.  In contrast, the Duke 690 and the Tiger 800 are faster than I need.  All of them are faster than the good old KLR.  If you are looking for a reference point, a BMW 328i has a "pounds per HP" of just over 15, so all of these are faster than a pretty good car, including the KLR.

Looking at weight including a full tank of fuel, the KLR on the bottom is my baseline.  At 375 pound with fuel and a theoretical 300 mile range, it's not doing too badly.  In comparison, the CCM GP450 weighs 75 pounds less and still has an acceptable 225 mile range in this comparison.  Now, I admit, I wouldn't want to go too much lower in fuel range, but the GP450 is just fine.  

The 640 LC4 Adventure is a nice older bike, comparable bike to my KLR.  It's power and weight aren't that different, but it does carry a massive 7.5 gallons of fuel and a 375 mile range to go with it.

The Duke 390 is pretty interesting.  A very modern 373 cc engine with excellent horsepower for it's size and a light 320 pounds with fuel.  It only has two issues.  The frame is too small for me (It might be possible with enough modification) and the fuel range is too small.

From a weight point of view, the Duke 690 is really very good, but it's fuel range is tiny.

That leaves the Tiger 800 and it is one nice bike, but it is also so heavy.  I don't understand why a bike that is the same size as the KLR has to weigh almost 500 pounds.  With lots of modern electronics, the Tiger (especially the 2015 XCx model) would be my long trip bike of choice, but I have a hard time getting past the price and the weight.

Anyway, I think my bank account is safe for now.  The CCM will take a while, if ever, to reach these shores.  The Duke 390 is too small for me and the Tiger too pricey and fat.  Still, I am happy to see these interesting new bikes come to market.  It has certainly stirred my interest, although I'll keep plugging along with the KLR for now.

Behind Again

Sometimes, doing the right thing just means more projects and me further behind.

I'm a big believer in being visible when riding a motorcycle on the road.  With so many things distracting drivers today, you've got to grab their attention so you don't get run over.  The tallest thing on the motorcycle is your helmet, so a strong, bright, high contrast color on a helmet gets the driver's attention from farther away than any other part of the motorcycle.  That's why I have taken the time to paint my helmets.

A helmet is designed to give you good protection for 5 years, 6 years in a pinch.  After that, the styrofoam liner has shrunk a little and the distance from your head and the liner increases your risk in an accident.

I have really enjoyed my Shoei X11, but 2014 was the 5th year and it was time to get a new helmet.  This last summer, I managed to find one that fits but somehow haven't gotten time to paint it.  At least I got a start on masking it.  In case you are wondering, I learned the hard way that you don't want to paint the vents.  Those things have switches that need to function and get clogged up with paint.  It makes finding a pleasing graphic pattern a challenge.

Wouldn't it be nice if I could buy one in the high visibility color?  They do exist, but my big, fat head has made it hard to find one that fits and meets my other needs.

It seems like the faster I go, the behinder I get.

Catching Up in the New Year

I know, I haven't posted in too long.  Since it's the new year, I thought I would catch up a bit.

I've ridden the 2001 KLR650 for 11 years and it's been a good fit for me.  Alas, about 2 years ago, it decided that it was a little bit British and started to leak oil.  I looked and looked and tried several approaches to fix what I thought was the leak.  I replaced output shaft seals, oil drain plug washers, anything and everything near the leak.  Finally, I found it.  There is a crack in the crankcase, running vertically through the treads of the oil drain.  #*!##**!

After much hemming and hawing, I decided that the only right way to fix this was to replace the crankcase with a good used one.  Rebuilding with a new part would have cost more than half the value of the bike, so used was the way to go.

Of course, at 35k miles, I would need to hone the cylinder at least and probably need to bore it and up the size of the piston and rings.  I guess you could say that I got a case of the "might as wells".

The lovely piston in the pictures is an aftermarket forged piston that reduces the mass by 25% and is said to significantly improve the vibration of the engine.  In addition, it bumps the displacement from 650 to 685 cc with a 2 mm bore increase.  Smoother and more torque, might as well indeed.

In case the piston looks a lot like a car piston, you would be correct.  The piston diameter is slightly more than 4".  Now you know why they call them thumpers.

Looks like I'm behind on projects again.  Combine that with travel for work and I better get busy.

Valentine's Day

So, I'm driving in the U.P. last week.  That's the Upper Peninnsula of Michigan for the rest of you trolls.  I'm listening to the radio and I hear an advertisement for Hampton Inn.  Allow me to paraphrase.

Remember last year when you got your lady some plastic flowers from the gas station for Valentine's Day?  Well, she remembers and she is still pissed.

Why don't you do it right this year and book a romantic Valentine's weekend at the Hampton Inn,   Green Bay?

February in Green Bay?  At the Hampton Inn?  I guess that is what passes for romantic in the U.P.

Customer Service? I don't think so.

About 5 years ago, I bought an all-in-one printer, a Canon.  It has done what I needed and, because I don't print that much stuff, it's still in excellent condition.  This is actually only the second computer printer I have owned.  The first one worked fine for 10 years and I only replaced it because I wanted to have a printer that did a better job with photographs.

I recently upgraded my computer and got the newest level of operating system as part of the deal.  Naturally, I go through and set-up all of my peripherals, including the printer.  Only the printer needs a driver.  Going to the Canon website I find that they don't have one for my new operating system and printer.  I contact Canon support and am told that my printer is too old and not enough people would be using my old printer with the new operating system.  It would be too much work to build a driver.  Not worth their effort.


The result is my printer is useless with my new computer.  It is basically a brick.  Canon's suggestion is that I should take advantage of a customer loyalty discount and buy a new printer.  FAT CHANCE!

So this is what passes for customer service these days, at least at Canon.  Perhaps in the whole consumer electronics industry.  They assume that they can force us into buying new hardware every few years just because they stop supporting software.  Unfortunately, short of a deeper understanding of Linux and writing my own software, it appears that they have me by the balls.

It's amazing that they can get away with this.  If the auto industry built a car that only lasted 5 years, we would get driven out of business so fast.  In fact, the average age of a car in the US market is now up to 11 years, so at least cars aren't being made completely obsolete.  My watch, my TV, my refrigerator, my alarm clock, everything in my house and including my house will last for years and years.  They won't become suddenly obsolete because somebody didn't write new software.  In fact, most things are only replaced when a worthwhile performance upgrade is worth the new price.

So what can I do about Canon and other companies of their like?  For now, I'm taking advantage of your indulgence in my little bitch session here.  I've also been on a few of the biggest retailers of Canon products and written reviews of their poor customer service.  Maybe, if we all took bad actors like Canon to task by stopping purchasing their products, and took advantage of social media, blogs, and website reviews to tell the tale, maybe they would hear us.

So, please do me the favor, stay away from Canon.  Also, let everyone know when you have similar grips with other companies.  Maybe, if we all work at this, we can make a difference.  Maybe, maybe customer service would begin to mean something again.

Hmmn...  I wonder if I need a printer at all.  Maybe I could just send my printer files to my local UPS store and have them be my printer.

Red Chair

It has been a pretty and long fall.  Last week, the wind came and blew all the leaves off the trees, but not before I snapped this shot.  Seems like a good spot for a daydream.

Another enjoyable element of this fall has been the creaky presence of the Sand Hill Cranes.  Many a time I've had 4 or 5 wandering around my yard and even past the red chair.  We have had more of them than I've seen in a long time (flocks of up to 50 gathering) and they stayed until a few days ago.  I guess that means that winter is truly here.

This has been an unusual year for me. Somehow, I've been busy all the time, but don't have anything to show for it.  Except maybe this picture and some motorcycle video that I need to edit.  It is hard to believe that in earlier years I had the time to post in this blog on a weekly basis.

Many folks think of spring as a hopeful season.  For me, that's fall.  I like to combine the cool weather and quiet with a combination of reflection and daydreaming a new future.  It's past time, so I better get at it.

Just a few little psi

Those of you who have read this blog will know, I can't stop tinkering with stuff.

About 3 years ago, I bought the Kawasaki ZRX1200R as the basis for a future project.  I figured, I wasn't ready for the project, but I could ride the bike in the meantime.  What I discovered was that the ZRX series had a reputation for being a poor handling bike and, upon riding it for a while, I had to agree.  Going in a straight line, everything was fine, but go over a dip in the road while cornering, you better hang on.  And don't even think about squeezing on the throttle in a turn.

The guy I bought the bike from told me I should make sure to run the factory tire pressures at 36 front/36 rear.  So that's what I did.

Trying to improve the handling, I messed with every suspension setting I could think of.  I managed to move the handling in the right direction, but she was still scary and I still wasn't confident.

One morning, on a pure lark, I decided to blow the tires up to 40 psi.  WOW!  What a difference.  Suddenly, you could feel the front end and the rear would follow the front.  When I got home, I googled ZRX tire pressures and found that lots of other people had discovered that the factory specs were just wrong.  They said that the right specs were 36/42.  I gave those a try, along with 40/42 which I settled on as best for me.  Now I can go through a dip with confidence.  Now I can squeeze that throttle on at the apex and track the bike smoothly out of the corner.  I had a little surprise when an oncoming car crossed into my lane on a corner.  Grabbing the front brake to slow and tighten my line caused a minor steering reaction, but well within control.

How amazing it is that a few little psi could change the character of a bike.

That got me to thinking.  What had probably been happening is that the contact patch of the tire in a corner was moving laterally when the vertical load changed going through a dip.  There just wasn't enough tire pressure to keep the tire's shape under different loading.

Of course, the current style is big, fat, wide tires on bikes.  I guess people think they look good.  But doesn't the fat tire cause the contact patch to move laterally when the bike leans?  Wouldn't the bikes handling be more consistent if the contact patch didn't move laterally as far in roll?  It always has seemed that skinny tires are the best handling on a bike.  I can't say it is the whole reason, but I can say that the KLR has skinny tires and keeps up with just about any sport bike ridden at the same skill level.  So keep your fat tire style.  I prefer skinny any day.

P.S.  Note to self.  Always Google any question that comes to mind.  There is often useful knowledge there and the factory spec isn't always right.
