A 2-sstroke quarter-liter machine like the 2010 MY YZ250 is a true weapon in the hands of a skilled rider. The engine delivers explosive power as the throttle is twisted and the brawn of this lightweight machine can strike fear in the minds of the faint-hearted. The aluminium frame uses inverted Kayaba forks and a works-derived rear suspension, both adjustable and capable to deliver first-class performance to the discerning rider.
Little has been improved over the previous edition, as it looks like Yamaha's current recipe is a successful one.
