New 2022 Yamaha WR450F Dirt Bike Motorcycle

• YZ450F-DERIVED BILATERAL BEAM FRAME: Yamaha’s refined aluminum frame provides high performance on technical, aggressive terrain sections and comfort for those long days in the saddle, with frame spars and engine mounts developed alongside the YZ450FX cross country racer to centralize mass for the best possible balance of bump absorption, stiffness and rider feel.
• COMPACT BODY AND SEAT DESIGN: The WR450F features stylish bodywork from tip to tail, including a large 2.15 gallon, mass-centralized fuel tank. The body design is narrow for more comfortable knee grip and control, while the seat gives the rider additional room to move. Even the rear fender is designed for added rigidity to make moving the machine easier.
• CLASS-LEADING SUSPENSION: The WR450F’s industry-leading, fully adjustable KYB® coil spring-type fork with speed sensitive damping provides exceptional balance between handling and bump absorption, with mid-speed valving tuned for improved feel at slower fork speeds.
• 270MM FRONT BRAKE: The large 270mm front disc brake coupled with aggressive pad material offers outstanding braking performance and machine control with exceptional stopping power.
• CROSS COUNTRY WHEELS AND TIRES: The WR450F features an 18-inch rear wheel to help prevent pinch flats and provide additional comfort across rough, broken terrain.

Engine

• CYLINDER DESIGN: The WR450F’s rear exhaust and forward-mounted intake system features a cylinder head design that works with the frame geometry for optimized weight distribution. The engine features a straight intake tract, aggressive cam profiles, high-compression “box bridge” piston design with DLC-coated piston pin and more.
• ENDURO ENGINE TUNING: WR450F-specfic ignition and fuel injection maps are optimized for enduro riding and racing for exceptionally smooth, controllable midrange and extended pulling power in the top-end.
• UNIQUE INTAKE AND EXHAUST SYSTEMS: The WR450F features an air filter that works in conjunction with the tuned intake tract length and a WR-specific muffler to boost the linear feeling of traction and drive. Not only is the WR450F muffler completely mechanical—eliminating the need to repack—it integrates a U.S. Forestry Service-compliant spark arrestor too.
• HIGH-CAPACITY RADIATOR AND FAN: The WR450F uses a large radiator with excellent cooling capacity shared with the YZ450F motocrosser, complete with a cooling fan for consistent performance during the toughest enduro rides.
• ELECTRIC STARTER SYSTEM: The WR450F features a compact electric starter system to simplify restarts on the trail and add convenience everywhere else.
• ADVANCED FUEL INJECTION: The engine breathes through a 44mm Mikuni® throttle body fed by a high-pressure electric pump to ensure optimum fuel atomization and power for a wide range of riding elevations and conditions.
