DETAILED DESCRIPTION

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. 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. The WR450F features industry leading KYB™ suspension tuned in concert with the chassis to produce excellent cornering performance, traction and bump absorption. With smooth chassis movement, the rider is able to make the most of the engine's exceptional power with confidence. 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. 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. The WR450F™ builds on Yamaha’s exceptional motocross race platform with added features and unique settings designed to optimize the WR for enduro riding. A combustion chamber geometry with steep valve angles, aggressive cam profiles, a high compression piston with low friction rings, long connection rod, large exhaust head pipe connector, high-flow air filter and efficient breather system work together to give WR450F riders a broad spread of useable thrust with expanded high-rpm power. All available with the convenient push-button starting that features a compact starter motor. 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. The Yamaha WR450F uses KYB® spring-type forks with industry-leading functionality and easy tuneability for a wide range of conditions. 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.
