2011 Yamaha YZ250F
The 2011 KTM YZ250F is a purpose-built 250, not a resized 450. The Bilateral Beam frame provides added cornering speed and stability, while the fuel tank is positioned close to the center of gravity for light handling. The optimized engine delivers power in the low-to midrange with great torque and power for blasting out of the corners.
