2023 WR450F
KEY FEATURES
ADDITIONAL FEATURES
Compact Headlight Unit
The WR450F’s 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.
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 compact meter has a high-contrast liquid crystal display with a fuel consumption indicator. The meter features two modes: Standard and Race. Standard mode displays the speedometer, two trips meters and clock functions while Race mode features average speed, timer and trip functionality along with low fuel and engine warning lights.
CHASSIS/SUSPENSION
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.
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.
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.
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.
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.
ENGINE
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.
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.
Electric Starter System
The WR450F features a compact electric starter system to simplify restarts on the trail and add convenience everywhere else.
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.
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.
Robust Transmission and Clutch
The WR450F’s wide-ratio 5-speed transmission provides the optimized gear for tight technical terrain, as well as wide open fire roads. The transmission gears use a wide surface area that is balanced against updated clutch components.
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.
TOP FEATURES
Advanced Frame
Yamaha’s aluminum frame features flex characteristics giving riders the ultimate combination of precise cornering performance, traction and bump stability. The frame is derived from the YZ450F to centralize mass and provide an ideal balance between cornering feel and straight-line confidence. The rigidity balance of the chassis is specifically tuned for enduro riding.
Bilateral Beam Frame
The WR450F aluminum frame features flex characteristics that give riders the ultimate combination of precise cornering performance, traction and bump stability. The rigidity balance of the chassis, as well as engine mounts, top triple clamp and front axle increases rider confidence.
Braking System
A rigid front caliper with large pad surface area aids feel and controllability. The front brake rotor dissipates heat efficiently for consistent performance under racing conditions.
Class-Leading Suspension
The Yamaha WR450F uses KYB® spring-type forks with industry-leading functionality and easy tuneability for a wide range of conditions.
Compact Cylinder Head
The WR450F features aggressive cam profiles, a high compression piston with low friction rings, long connection rod, large exhaust head pipe connector, a high-flow air filter, efficient breather system and a compact, lightweight magnesium valve cover.
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.
