An injection of hyperactivity.

With the all-new fuel-injected Yamaha YFZ450R, Yamaha has taken the existing notion of high performance race ATVs and given it a serious injection of racing passion. Wider, faster, even more serious, the new YFZ450R is designed to take an awesome design to a whole new level. The brand new fuel injection system with its big 42mm Mikuni throttle body and 12-hole injector provides exceptional atomisation of fuel for maximum power and unbelievably crisp power delivery. Then there’s the all new cockpit, with more room, more adjustability, softer contact plastics and more seat where you need it. Give the YFZ450R some extreme body English - it’s a machine that loves to do the talking.
