The 2011 MY YZ250F introduces premium 4-stroke competition-grade machinery to the skilled rider. The engine is a strong puller, but is much smoother than its 2-stroke counterpart, and thanks to the careful weight management, it doesn't make the YZ250F a heavy load. The bike is really easy to flick without massive effort from the rider, retaining exceptional ground tracking capabilities worth of a race bike.
Adjustable suspensions, optimized mass and top-drawer titanium valves for the engine add to the overall performance specs of this race-winning quarter-liter beast.
