Last of a disappearing breed? Not at Yamaha! Choice is a good thing and the more choices the better. Perhaps a 4-stroke MX bike is not the machine for you so we have taken some of the best features of our 4-stroke YZ line and have added them to the 2010 Yamaha YZ250, so it maintains its competitive edge.

We love the smell of premix in the morning.

Our legendary two-stroke is more potent than ever with a light aluminum frame housing a patented YPVS Power value-equipped engine that delivers great power-to-weight ratio. The 2010 YZ250 is ready to race out of the crate complete with ProTaper aluminum handlebar, titanium footpegs, gripper seat and Excel rims.
