2019 Yamaha WR450F

This off-road bike offers enhanced performance to make this aggressive trail machine much closer to its YZ and FX brothers.

Features may include:

• New for 2019

For 2019, the new WR450F takes all the latest advancements found on the YZ450F and builds upon them to create the ultimate trail-ready enduro machine, with engine and chassis tuning optimized for accessible power, handling balance, and flexibility on every trail.

• Engine

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.

The WR450F features a new two-piece air filter with improved sealing that works in conjunction with the tuned intake tract length and new WR-specific muffler to boost the linear feeling of traction and drive.

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.

• Chassis/Suspension

Yamaha’s refined aluminum frame provides rigidity and durability, 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.

The WR450F features stylish bodywork from tip to tail, including a large 2.15 gallon, mass-centralized fuel tank shared with the YZ450FX™. The body design is narrow for more comfortable knee grip and control feeling while the narrower seat gives the rider additional room to move aboard the machine. Even the rear fender is specially 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 updated mid-speed valving for improved feel at slower fork speeds. The linkage type rear suspension features a KYB® shock features a new coil spring for lighter weight without sacrificing durability as well as a larger oil reservoir for more consistent damping.

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