Model Name:YZ450F

Manufacturer:YAMAHA

Model Year:2006

YZ450F had been leaving its mark as the pioneer of a 4-stroke motocrosser motorcycle. Its MY2007 had improved it power characteristics and reliability by changing its exhaust valve timing, carburetor setting, ignition timing, balancer ratio, clutch system, exhaust pipe diameter, and its handling characteristics. It became even more maneuverable by using light aluminum forged parts to its front area, adopting a wave disc rotor, or remodeling its rear suspension.
