Yes it is Race-tech's Motorcycle Suspension Bible. The information is crucial to most motorcycle tuners. In hillclimbing, we stretch swingarms, put street bike motors in dirt bike chassis, and have a variety of terrain. In supermoto Paul points out that currently supermoto bikes have horrible ground trail numbers. Correcting it lowered seconds off of lap times for experts and typical riders. Street bikes need to corner safely, and have pich control, and everyone gets the demands of sx and mx suspension. He also points out that a large majority of riders never attempt to adjust their suspension. This is because barely anyone understands it, and are afraid to mess it up and make things worse. Often newer trade-ins are still set at factory positions. Really, if we take note of where we are set, then we remove the risk of messing things up, because we can always go back. Stock suspensions are set-up for the "average rider." How difficult would that be to get right for all types of riding and skill levels? (not to mention riders weight, build and riding style.) I did learn a whole lot about suspension, and still have alot to understand, but it also pointed out that, when in doubt, ask an expert. Race-tech also has a policy to answer questions and have techs on the phone to help you basically all day. When you buy a gold valve from them, they provide an installation kit and a how-to video that covers the installation. Of course, the book also covers their tools, and products and are perfectly captured label facing out in the pictures, but somehow with the overwhelming support and clear information, it seems fair enough......as far as where to get it, I found it on ebay, new 37 dollars, but beware of shipping times. They sent my copy media rate which is twice as long as typical shipping......
