2003 Yamaha YZ 250 F – Motorcycle


If there’s one bike that started a revolution it’s the Yamaha YZ250F. This sudden surge of technology and development changed the face of motocross and it all started with the impressive Yamaha YZ250F.  The Yamaha YZ250F is powered by a 250cc liquid-cooled Single.  Yamaha still uses a carburetor on the YZ250F but the transition to a fuel-injection system is anticipated in the immediate future. Yamaha also continues to offer customers a choice of color with the YZ250F in the standard blue and white color scheme or a limited-edition version in black, red and white.
