The 85cc liquid cooled engine features the Yamaha Power Valve System (YPVS) that boosts overall performance and contributes towards the bike’s easy to use torque. Running with a high compression ratio – and equipped with a close ratio 6-speed transmission – the YZ85 delivers outstanding acceleration with race winning power.

Lightweight chassis design
Lightweight chassis design

Built for demanding junior racers, the YZ85LW's chassis is optimised for strength, rigidity and overall handling stability. The aluminium swingarm offers refined balance between longitudinal and torsional rigidity, and the removable rear subframe constructed from lightweight, high-strength aluminium reduces weight.

Fully adjustable front forks
