Specifications

Features

Next-Gen Enduro Racer Based on Flagship YZ450F™ The WR450F™ builds on Yamaha’s exceptional motocross race platform with added features and unique settings designed to optimize the WR® for enduro riding.
Potent Electric Start Engine A high-compression cylinder head, forged piston, aggressive cam profiles, cylinder geometry and much more work together to give WR450F riders a broad spread of useable thrust with expanded high-rpm power. All available with the convenient push of a button starting that features a compact starter motor system battery.
Advanced Alloy Frame Yamaha’s bilateral beam aluminum frame is derived straight from the YZ450F to centralize mass and provide an ideal balance between cornering feel and straight-line confidence.
Class-Leading Suspension Yamaha uses KYB® spring-type forks on the WR450F, with industry leading functionality and easy tuneability for a wide range of conditions.
EPA-Compliant Emissions Thanks to carefully balanced ECU tuning and the Forestry Service-complaint spark arrestor-type muffler, the WR450F is ready to go where you want, when you want.

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.
Enduro Engine Tuning 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.
High-Capacity Radiator 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.
Robust Transmission and Clutch The WR450F’s wide-ratio 5-speed transmission is shared with the YZ450FX, providing the optimized gear for tight technical terrain as well as wide open fire roads. The clutch system has been developed especially for the WR450F for improved heat dissipation and lighter clutch lever effort.

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.
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 Large 270mm front disc brake coupled with aggressive pad material offers outstanding braking performance and machine control, with exceptional stopping power and controllability.
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.

Enduro-Ready Detailing 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.
Compact Headlight Unit The WR450F’s updated headlight fairing and compact taillight unit centralize mass and improve the racy, agile styling of the machine.
Embedded Graphics Yamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage.
