Engine FeaturesThe fuel-injected 449cc engine has superb power characteristics. Power delivery is smooth and strong off the line with lots of low and mid range where you need it.
The crankcase holds a crankshaft thats ready to handle the increased balance ratio, as well as a counterbalancer for superior vibration control. The crankcase also houses the oil tank, which helps to centralize mass for unmatched handling and makes maintenance easier.
Camshafts are designed to maximize the torque available in the low and mid ranges.
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.
Chassis/Suspension FeaturesThe chassis is very spacious, allowing room for even an aggressive racer to move around, and the ATVs body panels that the rider contacts during operation are of a special, softer plastic material for greater comfort. The seat is narrow in the front, yet wide and padded in the rear to provide a more comfortable ride, even when hanging off on the side of the seat in a turn.
ProTaper® handlebars are mounted on 4-way clamps for exceptional adjustability. There are two sets of holes in the handlebar crown, and eccentric clamps so the rider can choose the standard setting, 10mm or 20mm forward, or 10mm back.
The wheel has been redesigned, with the inner lip rolled in. This increases the rigidity, allowing a reduction in weight while maintaining strength.
Foot pegs are a generous 2.6 inches wide, something riders will appreciate every time they want to get up on the pegs, with good kick-up on the ends for solid footing.
The frame is aluminum for lightweight, except for the frame member under the engine. Here tensioned steel is used for its combination of strength and thinness. This allowed the designers to sit the engine lower overall for excellent mass centralization for unmatched handling. The frame is bolted together, rather than welded, for maximum durability.
The front frame is noticeably narrow at the A-arm mounting points. This dramatically reduces changes in camber as the long A-arms travel through their full range of motion. The front 44mm KYB® shocks have Kashima coating for smooth operation with superb bump absorption and excellent anti-bottoming characteristics. The 9.4 inches of wheel travel means this racer is up to even the most challenging tracks.
The rear swingarm is crafted of strong, gravity-fed aluminum, and its matched to a fully adjustable 46mm KYB® piggyback shock absorber for excellent handling. Rear wheel travel is 11.0 inches for comfort even on tough terrain.
For excellent stopping ability, YFZ450X features dual front hydraulic disc brakes and a trick looking, lightweight wave-type rear rotor.
Additional FeaturesThe throttle lever requires low effort, and its very comfortable to use. That means less fatigue during all-day riding.
The instrumentation is all business. The discrete panel on the fender in front of the rider gives vital indicators about low fuel, coolant temperature, check engine, and neutral gear via a straightforward LED display.
