Book Review: Modern Motorcycle Technology: How Every Part of Your Motorcycle Works
Modern Motorcycle Technology: How Every Part of Your Motorcycle Works
by Massimo Clarke, 2010
All Rights Reserved © 2012 Thomas W. DayMassimo Clarke is an Italian version of Cycle World's Kevin Cameron. Clarke has several motorcycle books to his name, was the technical editor of Motosprint, and is currently a Director for Assomotoracing. (If you can figure out what this organization does, please explain.) Clarke's grasp of technology is excellent and his ability to quickly describe the function, advantages and disadvantages, and evolution of machines and their parts is why this book is worth reading. The photographs and illustrations, on the other hand, are what make Modern Motorcycle Technology fun to look at and browse through.
For me, this was not a cover-to-cover read. Instead, I skipped around to read about subjects that interested me at the moment; starting with "Intake and Exhaust." I followed that with going back to the beginning for "Engine Design" and "Structure and Function." While I have a decent basic understanding of internal combustion engine operation, there is no subtlety to what I know. When I'm troubleshooting, "suck, squeeze, bang, and blow" is about all the theory I use to stumble my way through solving engine problems. Clarke's detailed explanation of how the myriad of engine systems work and how the various one, two, three, and four cylinder configurations provide power, reduce vibration and instability, control heat, convert fuel to energy, and how design engineers compensate for the weaknesses of the basic design they have chosen was worth the price of the book. There are useful descriptions of the reliability sacrifices several engine designs make in the hunt for superior performance.
If you ever wanted to know what manufacturing processes were used for the various parts of your motorcycle, this book is for you. If you're interested in more than surface-level motorcycle metallurgy, fuel system chemistry, and frame and suspension geometry and physics, this book is for you. If you want to know the real effect of exhaust and intake modifications on the design intention of your motorcycle, Clark has a whole chapter just for you. Transmission? Exhaust emissions? Frame geometry? Suspension parts? Wheels and tires? Electronic components? It's all there and with enough detail to provide a decent background on how each of these bike bits works.
I can't decide if I'm going to keep my copy of Modern Motorcycle Technology in the bathroom/library or in the garage. It's good recreational reading, but it's also detailed enough to be useful as reinforcement to my service and owner's manuals, when I'm stuck troubleshooting some unusual problem. I might need two copies.
This Is Awesome
The “lead” motorcyclist has no more business on a vehicle with a motor than does a squirrel. Neither of these two squids are half the rider the bicyclist is. None of that is surprising, though. Spend a Saturday in Red Wing and you’ll see why motorcycle fatalities are grossly out of porportion to the number of motorcycles on the road. It’s an embarrassment.
Crash Data via NHTSA and DOT
The data is always a good bit of behind current trends, mostly because getting information from many of the states is like pulling teeth. This is 2014 data, but it’s still interesting to pick apart.
I can’t imagine how they generate this over-optimistic estimate, “In 2013, motorcyclists were about 26 times more likely than passenger car occupants to die in a crash per vehicle mile traveled and five times more likely to be injured.” I just don’t buy the idea that motorcycles are that large a contributor to miles-traveled in the US. I still believe we are barely 0.001% of total miles traveled (well under bicycle miles) and, therefore, closer to 1,000 times-or-greater more likely to die per mile traveled, annually.
“There were about 8.4 million motorcycles on the road in 2014.” Yeah, no. I call bullshit.
“In 2014, 39 percent of those motorcyclists killed were not wearing helmets, down from 41 percent in 2013.” Seriously interesting.
“Over the nine years from 2004 to 2013, fatalities among the 40-and-older age group increased by 39 percent, according to NHTSA, compared to 16 percent for all ages.” Expected, since the average age of motorcyclists is climbing at about that rate.
TOP FIVE STATES IN MOTORCYCLE THEFTS, 2015
- California 7,221
- Florida 4,758
- Texas 3,403
- South Carolina 2,160
- New York 1,902
Huh? What’s with South Carolina?
“Older riders appear to sustain more serious injuries than younger riders.” No surprise there.
This is an interesting stat, “riders of ‘super sports’ motorcycles have driver death rates per 10,000 registered vehicles nearly four times higher than those for drivers of other types of motorcycles.” Sort of fits my one hazardous moment in Colorado last week.
This will be the death of public road access for motorcycles, “The Government Accounting Office (GAO) estimated that in 2010 motorcycle crashes cost $16 billion in direct costs such as emergency services, medical costs including rehabilitation, property damage, loss of market productivity including lost wages, loss in household productivity and insurance costs, including claims and the cost of defense attorneys. ” This number will contine to climb and the percentage of costs will skyrocket as cars become smarter and motorcyclists continue to get dumber.

REVIEW: Patrick Lacey - Sleep Paralysis
Does Anyone See A Trend Here?
* A Mankato, Minn., man was injured at 12:19 p.m. when his 2014 Victory motorcycle hit a deer on Minnesota Highway 16 west of Peterson in Fillmore County. Police say Mark Fromm, 59, was flown to a hospital with non-life-threatening injuries.
* On Saturday, a 55-year-old Oakdale, Minn., woman who was a passenger on a 2006 Harley-Davidson was killed about 3:25 p.m. on U.S. Highway 61 in Goodhue County when the motorcycle ran off the road and hit a sign. The State Patrol identified the woman as Janean Thielman. The driver, Joseph Frisch, 55, of Madelia, Minn., was seriously injured.
* The driver of a 2006 Harley-Davidson and his passenger died about 3 p.m. Saturday when their motorcycle crossed over the center line on eastbound Minnesota Highway 95 in Chisago County and struck another vehicle, triggering a three-car crash. Collin Orth, 35, of Milaca, Minn., and his passenger, Sara Orth, 34, of Milaca, died in the crash.
* An Appleton, Wis., man and a female passenger on his 2014 Harley-Davidson were injured when the motorcycle struck a deer at 8:30 a.m. Saturday on southbound U.S. Highway 53 in International Falls. Mark Natzke, 53, and his passenger, Tammy Natzke, 53, were transported to the hospital with non-life-threatening injuries.
* A fourth motorcyclist was killed earlier in the week after his 2013 Victory hit a deer about 3:15 p.m. Wednesday on Minnesota Highway 223 in Clearwater. The man was identified by the State Patrol as 61-year-old Richard Engen of Clearbrook.
After reading this list of crash descriptions, my wife said, “They ought to sell those machines with a theme song, ‘All My Trials, Lord.’” She gets it. Deer or no deer, it doesn’t appear that anyone can ride those hippobikes competently.
Back in My Day, It Ain’t Over
In last month's MMM column, "Back in My Day,' I wrote, “Not only can you not go back, you can’t even go where we went.” Turns out, I was wrong. On the way to Valentine, Nebraska I discovered that some of those old unmaintained roads still exist in my old home state. I even took a picture of one. I even hiked up that road a ways to discover that it quickly turned into deep, soft sand that would have put me and my V-Strom down as quickly as Raylan Givens takes out a Chicago mobster (look it up). On the other hand, if I'd have been there with my WR? I'd be on it fast and hard. It was a beautiful road, just not for a road bike.
The good news is that any kid with a dirt bike and a Nebraska home address can still have the kind of fun and make the discoveries I did 40 years ago. I love that. It has been years since I’ve seen a “Minimum Maintenance Road” sign and it makes me feel good (and a little younger) to know there are still some left.
