Featuring the Yamaha Power Valve System (YPVS), fully-adjustable suspension, six-speed transmission and adjustable ergonomics, the YZ85LW is ready to win races straight off the dealership floor.
YPVS™ Two-Stroke Power
The 85cc liquid-cooled, two-stroke engine features the Yamaha Power Valve System (YPVS™) for increased low- and mid-range power without losing peak power at high rpms, reducing the need for frequent shifting.
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.
FULLY-ADJUSTABLE SUSPENSION
Lightweight 36mm KYB® inverted cartridge fork features low-friction outer tubes, external compression and rebound damping adjustability, paired with a race-proven fully-adjustable KYB® rear shock. Both offer loads of suspension travel to tackle serious off-road competition.
