Segment: Enduro/Offroad
Production years: 2006, 2007
The 2007 MY WR250F carries on Yamaha's heritage: a bike with strong YZ-series spirit and enduro-friendly performance for weekend fun at the dirt track on along the moist forest trails or out in the open fields. A new engine was installed in the 2007 MY, also derived from the competition YZ one, with the revised cam shafts now offering a more useable low- and mid-range torque.
The all-new aluminium frame and suspensions also have a lot of YZ DNA, just like the new airbox and radiators. The brakes, seat and fuel tank are also new, being engineered in a more YZ, works way for increased performance and dependability.
