YZ250 Monster Energy
The combination of a high-powered 250cc 2-stroke YPVS (Yamaha Power Valve System) engine, lightweight aluminium chassis and one of the best suspension packages in its class makes this bike like no other and one of the most exciting motocross bikes you’ll ever ride. In its time it’s won everything worth winning in motocross, supercross and freestyle MX. Now Yamaha have made it even sharper!
The all-new slimline bodywork makes for a dynamic and ultra-modern look – and the flatter seat enables easier bodyweight shifting when accelerating, cornering or braking – for a higher degree of control. While the new more powerful front braking system and revised suspension damping help to cut lap times. And in its exclusive black livery with factory team-style graphics, the YZ250 Monster Energy Yamaha Racing Edition is the most desirable 2-stroke!
