Sportbike Performance Handbook

The suspension expert’s illustrated, comprehensive troubleshooting guide for dirt, street, and supermoto—with a solution to virtually any problem. Suspension is probably the most misunderstood aspect of motorcycle performance. This book, by America’s premier suspension specialist, makes the art and science of suspension tuning accessible to professional and backyard motorcycle mechanics alike. Based on Paul Thede’s wildly popular Race Tech Suspension Seminars, this step-by-step guide shows anyone how to make their bike, or their kid’s, handle like a pro’s. Thede gives a clear account of the three forces of suspension that you must understand to make accurate assessments of your suspension’s condition. He outlines testing procedures that will help you gauge how well you’re improving your suspension, along with your riding. And, if you’re inclined to perfect your bike’s handling, he even explains the black art of chassis geometry. Finally, step-by-step photos of suspension disassembly and assembly help you rebuild your forks and shocks for optimum performance.
