1993-2002 Yamaha Badger 80 YFM80 ATV Service Repair Workshop Manual VEHICLE/EQUIPMENT INTRODUCTION: The Yamaha Badger 80 (YFM80) is one of the most popular youth ATVs ever produced, designed specifically as an entry-level four-wheeler for young riders ages 12 and up. Yamaha introduced the Badger 80 in 1993 and kept it in production through 2002, earning its reputation as the most reliable, safest, and best-built 80cc ATV on the market. It was the first ATV for an entire generation of riders who went on to become lifelong Yamaha enthusiasts, and many of these machines are still running strong decades later thanks to Yamaha legendary build quality. At the heart of the Badger 80 is a proven 79cc air-cooled two-stroke single-cylinder engine with Yamaha Autolube oil injection system, eliminating the need for premixed fuel. The electric-start and kick-start models provide reliable starting in all conditions. Power is transmitted through a fully automatic centrifugal clutch CVT to a solid rear axle, with a simple twist-and-go throttle operation that makes it manageable for young riders. The suspension features front independent double wishbone A-arm design and a rear solid axle with swingarm and dual shock absorbers, providing a comfortable ride on trails and fields. A throttle limiter screw allows parents to restrict top speed for younger or less experienced riders, and the compact dimensions and manageable weight make the YFM80 easy to transport and maintain.
