The YFZ-450R SE is motocross ready. The weldless frame is designed from lightweight aluminum, with a tension-steel bottom frame that lets the engine sit lower for excellent mass centralization. Suspension components and settings reduce weight while providing light, agile handling characteristics with an excellent balance of sharp handling and rider comfort.
The YFZ-450R SE incorporates Yamaha Fuel Injection for precise fuel delivery. With a 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.
