The Yamaha YZ85LW is the large-wheel version of the YZ85 youth motocrosser. It uses larger wheels and a taller seat than the standard YZ85, making it better suited to bigger young riders on their way to a full-size bike.
It shares the YZ85's 85cc two-stroke single, which gained Yamaha's YPVS power valve in 2019, along with a six-speed gearbox and race-spec suspension. It is a closed-course competition machine. Rivals include the KTM 85 SX 19/16 and Kawasaki KX85.
