Nearly three inches wider overall than the YFZ450, the stance of this new 450R is motocross-ready. The frame is designed of lightweight aluminium, with a tension-steel bottom frame that lets the engine sit lower for excellent mass centralization. Suspension components have more travel carefully chosen for best performance, and the front shock bodies feature Kashima coating for even smoother operation.Yamaha YFZ450R is designed to be comfortable. It? much roomier, with plenty of room to hang off in the corners, and the seat is padded just right! Handlebars are 4-position adjustable, too, so every rider can choose the best position, and the throttle has been designed for all day comfort. What? more, the engine balancer has been revised to even further reduce vibration.This 449cc engine uses the cylinder head and cylinder from the championship-winning YZ450 for awesome power output. That means titanium five-valve cylinder head technology, with a camshaft designed just for this machine to deliver abundant low to midrange torque for performance where you can really use it to take the lead ?while still maintaining a super strong top end to let you pull away from the pack.The YFZ450R adopts fuel injection for precise fuel delivery. With big 42mm Mikuni?throttle body and 12-hole injector, this system provides exceptional atomization of the fuel for maximum power. The system also includes ISC (Idle Speed Control) for easy, reliable start-up and warming.This ATV is designed to make race prep easy. Body panels come off easily for service; there? no need to remove the battery or other components to get the fenders off. The aluminium frame is bolted together, rather than welded, for maximum durability. And the oil tank is integrated with the crankcase so it? easier to service the engine.
