Delivering a small-bike package with big Yamaha performance, the YZ85 is built for fun and built to win.

New for 2027, the potent 85cc liquid-cooled, two-stroke engine's intake system now features the VForce4R reed valve, while the exhaust system’s YPVS settings were also revised, resulting in a wider powerband and enhanced rideability across the entire rev range.

The chassis is built for the best up-and-comers with strength, rigidity and overall handling stability. The aluminium swingarm balances longitudinal and torsional rigidity, and the removable rear subframe constructed from lightweight, high-strength aluminium reduces weight.
