The Yamaha YZ250F is a motocross motorcycle first released in 2001 by Yamaha. It features a DOHC, four-stroke engine and initially had a steel frame and subframe in 2001–2002. In 2003 it received an aluminum subframe, which was replaced in the 2006 model with an all-aluminum frame.
The YZ250F has been praised for combining the broad-power characteristics of a four-stroke engine with the light handling more common in smaller, 125 cc two-stroke motorcycles.Dirck Edge, "2001 Yamaha YZ250F: MD Ride Review", MotorcycleDaily.com, retrieve March, 2007
