2020 Yamaha WR450FTHE BIKE FOR ALL REASONS
This off-road bike offers enhanced performance to make this aggressive trail machine much closer to its YZ and FX brothers.
Features may include:ENGINE
- Rearward-Slanted Cylinder Design
The WR450F’s distinct rearward-slanted cylinder design—complete with rear exhaust and forward-mounted intake system—features a cylinder head that works with the frame geometry for optimized weight distribution. Inside, the engine features a straight intake tract, aggressive cam profiles, high-compression “box bridge” piston design with DLC-coated piston pin, and more.
WR450F-specfic ignition and fuel injection maps are optimized for enduro riding and racing, for exceptionally smooth and controllable midrange power with longer-lasting pulling power in the top-end.
- Unique Intake and Exhaust Systems
The WR450F features a two-piece 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.CHASSIS/SUSPENSION
- YZ450F-Derived Bilateral Beam Frame
Yamaha’s refined aluminum frame provides high performance on technical, aggressive terrain sections as well as 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 feeling.
- 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 feeling while the seat gives the rider additional room to move aboard the machine. Even the rear fender is designed for added rigidity to make moving the machine easier.
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.ADDITIONAL
The WR450F includes a range of enduro-specific upgrades compared to the YZ450F motocrosser, including a wide, full-coverage composite engine guard, 18-inch rear wheel, large 2.15-gallon fuel tank, radiator fan, sealed O-ring chain, fuel level and engine warning lights, steel rear sprocket and a high-mounted folding aluminum kickstand.
- Multi-Function Enduro Meter
The display’s Standard mode features the speedometer, two trips meters and clock functions, while Race mode features average speed, timer and trip functionality.
The WR450F’s updated headlight fairing and compact taillight unit centralize mass and improve the racy, agile styling of the machine.
