Yamaha YFZ450R

MT-07 DT

The Walker Fowler Racing GBC Moto-Xperts Yamaha YFZ450R race ATV begins as a production base model and becomes constructed into the GNCC Pro XC1 championship collecting machine you now see today. Boasting podium-topping DNA and serious race pedigree, it is the unmatched, race-ready sport ATV for those who want to win. The Yamaha YFZ450R combines a high-tech, quick-revving, titanium-valved, 449cc fuel-injected engine with a lightweight, professional-caliber cast aluminum/steel chassis. Top features include an advanced frame, aggressive bodywork, assist-and-slipper clutch, and a large 42mm Mikuni throttle body and 12-hole injector fuel injection delivery system. The overall YFZ450R power and chassis combination makes for a proven championship-winning machine time-and-time again.
