The Yamaha YZ 85 appeared in 2002 as a budget version of full-fledged motocross bikes designed for motocross training for children and teenagers up to 16 years old. For adults, the Yamaha YZ85 LW (Large Wheel) version is offered in parallel, equipped with 19 'and 16' wheels (instead of 17 'and 14' on the regular YZ85).
The model was based on a 1-cylinder 2-stroke liquid-cooled engine, with a volume of about 85 cm³, producing 29 hp. power and 17 Nm of torque.
Other features of the Yamaha YZ85 / YZ85 LW include a steel frame, fully adjustable sports suspensions, disc brakes, a 5 liter fuel tank, a 6-speed gearbox, a carburetor power system and from 71 kg of curb weight.
Since 2015, the model has received minor changes in the ergonomics and geometry of the chassis, while the external motorcycle has not changed in any way. In 2019, the model received new brake discs (petal), a slightly increased curb weight (by 2 kg), as well as improvements in ergonomics, which slightly affected the overall dimensions.
