2010 Yamaha YZ250F
The all new, Bilateral Beam frame is specific to the 250F and is more compact than the previous generation chassis for superior cornering. The optimized engine delivers a new level of power in the low-to-midrange, with a great torquey feel, exactly where riders want it.
Two days around the National-prepped Washougal Motocross Park on the 2010 Yamaha YZ250F was dirt bike heaven. The redesigned 2010 YZ250F is much different from older models, and from the newest batch of 250F MX bikes.
