The Yamaha YZ85 is Yamaha's youth motocrosser for young racers moving up from 65cc bikes. It uses a liquid-cooled 85cc two-stroke single with a six-speed gearbox in a race-ready chassis.
A major update in 2019 brought the YPVS power valve, a new frame and new bodywork. It is a closed-course competition machine. The YZ85LW version has larger wheels for taller riders. Rivals include the KTM 85 SX, Kawasaki KX85 and Husqvarna TC 85.
