2023 Yamaha YZ85LW: GO BIG.

Introducing the new 2023 Yamaha YZ85LW…

Same YZ85 power, same YZ85 fun, equipped with a large wheel package allowing riders to bridge the gap to the next class.

Boasting many premium features to earn its stripes in the YZ lineup, the YZ85LW is ready to win races straight off the dealership floor.

LARGER FRONT & REAR WHEEL

The YZ85 Large Wheel (LW) model raises the bar for off-road capability with a larger 19-inch front wheel and 16-inch rear wheel clad in high performance 70/100/19 front and 90/100/16 rear Dunlop® MX3S tires. Perfect for the advanced 85cc rider looking for a more “big-bike” feel.

POTENT YPVS™ TWO-STROKE ENGINE

The 85cc liquid-cooled, two-stroke engine features the Yamaha Power Valve System for broad power across the rev range without losing peak power at high rpm—improving rideability and reducing the need for frequent shifting.

OPTIMIZED CHASSIS DESIGN

Built for demanding junior racers, the YZ85 LW’s chassis is optimized for strength, rigidity and overall handling stability. The aluminum swingarm offers refined balance between longitudinal and torsional rigidity, and the removable rear subframe constructed from lightweight, high-strength aluminum reduces weight.
