2013 Yamaha YFZ450R
The 2013 Yamaha YFZ450R comes with the discrete panel on the fender in front of the rider which gives vital indicators about low fuel, coolant temperature, check engine, and neutral gear via a straightforward LED display. It 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 as on previous model. Suspension components have more travel, carefully chosen for best performance, and the front shock bodies feature Kashima coating for even smoother operation just like on its brother YFZ 450. It is powered by 449cc engine that uses 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 among others products such as KTM 505 SX, Quadsport Z400, Honda TRX450R, and Kawasaki KFX450R. With big 42mm Mikuni® throttle body and 12-hole injector, fuel injection system provides exceptional atomization of the fuel for maximum power.

2013 Yamaha YFZ450R Features
Engine and Transmission – The fuel-injected 449cc engine has superb power characteristics, power delivery is smooth and strong off the line with lots of low and mid range. Fuel injection uses a 12-hole injector that provides exceptional atomization of the fuel for maximum combustion efficiency and power delivery. The system also uses a big, 42mm Mikuni® throttle body and includes ISC (Idle Speed Control) for easy, reliable start-up and warming. The crankcase holds a crankshaft that’s ready to handle the increased balance ratio, as well as a counter-balancer for superior vibration control, it is designed to maximize the torque available in the low and mid ranges.
Chassis and Suspension – The chassis is very spacious, allowing room for even an aggressive racer to move around during the moto, and the ATV’s body panels that the rider contacts during operation are of a softer plastic material for greater comfort. The frame is aluminum for lightweight, except for the frame member under the engine. The rear swing-arm is crafted of strong, gravity-fed aluminum, and it’s matched to a fully adjustable 46mm KYB® piggyback shock absorber for excellent handling. The wheel has been designed with the inner lip rolled in, set motocross-spec wide, near the maximum allowable 50 inches, for great cornering ability. The Dunlop® tires are grippy with a great pattern for cornering, and at 20 inches in the rear and 21 inches in the front, provide much better ground clearance than the competition. Dual front hydraulic disc brakes and a trick looking, lightweight wave-type rear rotor for excellent stopping ability on 2013 Yamaha YFZ450R.
