85cc Large Wheel

The YZ85LW (Large Wheel) model takes the race-winning YZ85 formula and enhances off-road capability even more with the addition of a larger 19-inch front wheel and 16-inch rear wheel wrapped in high performance Dunlop MX3S tyres.

Along with its proven liquid-cooled YPVS-equipped 85cc powerplant, fully adjustable suspension and large diameter brakes, the YZ85LW boasts numerous enhancements to expand its overall performance.

Rider ergonomics have been improved by way of a narrower tank design, flatter seat, side covers and slimmer, symmetrical radiator shrouds. This enables greater freedom of movement for smooth shifting of body weight and better machine control.

For demanding junior racers, the YZ85LW has been enhanced in several key chassis areas to optimise strength and rigidity, including revisions to the main frame, longer swingarm and rear wheel axle. The aluminium swingarm was redesigned to enhance balance between longitudinal and torsional rigidity for improved handling stability. A removable rear subframe constructed from lightweight, high-strength aluminium reduces weight. The rear brake master cylinder now has a built-in sub-reservoir providing more linear brake response and increased control.
