Off-road riding is one of motorcycling's most popular pursuits and also one of its best training grounds for improving street-riding skills. Off-road riding takes many forms, from motocross and enduro racing, to dual-sport day trips, to trail riding, to adventure tours. No matter the specific pursuit, all dirt riding (and much street riding) shares the same basic skill set. How to Ride Off-Road Motorcycles schools the reader in all the skills necessary to ride safely and quickly off-road. Chapters cover the basics, such as body position, turning, braking, and throttle control, then proceed to advanced techniques, such as sliding, jumps, wheelies, hill-climbing, and more. If you've ever wanted to try dirt riding or if you're an experienced rider looking to sharpen your skill set, How to Ride Off-Road Motorcycles is a perfect riding coach.

With millions of participants worldwide, motocross and off-road motorcycle riding are the most popular amateur motorsports in the world—and, many agree, the most physically demanding. For a sport that asks so much of so many, a training manual is a must—and this one is the very first to make the necessary know-how accessible to the amateur rider. While providing sound advice for the would-be Ricky Carmichael of tomorrow, this handbook offers a no-nonsense, real-world approach that the average racer or rider can understand—and turn into real results. Among the topics the book covers are: weight training and proper nutrition in a fast-food world; age-specific training programs; gear; scheduling; staying hydrated, healthy, and injury-free: keeping a log; cross-training; balance, reflexes, and flexibility—and how to improve all three; race-day warm-ups and stretches; arm pump and how to train it out of your system; taking it to the next level—for the would-be pro riders; trainers, gyms, online, and published guidance; and staying motivated and avoiding burnout.

The fast-growing sport of off-road racing attracts legions of enthusiasts--the AMA estimates nearly one million participants in 2003--who spend much of their free time riding and modifying their motorcycles. This how-to manual offers those riders all they need to know to modify their bike in order to make it work the best for their particular riding conditions. The book covers everything from basic maintenance through to performance modifications, and is authored by one of the most respected performance gurus in the business.
