Detailed: 2021 Yamaha WR450F

Minor changes also confirmed for latest 2021 Yamaha WR250F model.

An all-new 2021 Yamaha WR450F has officially been uncovered by Yamaha, based on the latest YZ450F motocross model and further developed to specifically meet the requirements of serious off-road and enduro riding.

Designed with the flexibility to win in the tightest enduro conditions as well as fast, rough, open trails, the newest WR450F features a refined, more efficient engine, a redesigned frame with all-new flex characteristics, updated suspension settings, and more.

The 2021 WR450F is designed to perform in the widest range of conditions. The new 449cc, liquid-cooled, four-stroke, electric start engine features an all-new compact cylinder-head with redesigned combustion chamber shape and steeper valve angles.

The forward-positioned downdraft intake with rear exhaust powerplant houses a higher compression piston with low friction rings attached to a longer connecting rod. The wide ratio, five-speed transmission has been refined to provide smoother shifting and a more efficient crankcase breather system has been adopted to decrease pumping losses.

In all, the lighter, more compact engine produces increased power across the entire rpm range for stronger and more linear pulling power. It also boasts smartphone adjustability via the Power Tuner app and has a handlebar-mounted map switch to adjust two selectable maps on the fly.

The latest evolution of Yamaha’s lightweight aluminum bilateral beam frame has been redesigned with new wall thicknesses and flex characteristics that provide improved cornering performance, traction and bump reaction to give the rider more confidence to push harder in any off-road condition.

Other chassis components such as engine mounts, top triple clamp and front axle, as well as the class-leading KYB suspension with enhanced compression and rebound characteristics were carefully refined to reduce weight while improving handling and performance.

To bring the new package to a stop, the 2021 WR450F features a newly designed front brake caliper, brake pads and front disc. The combined changes deliver increased power output with more controllable, linear acceleration and lightweight handling characteristics.

A more compact electric start system, advanced fuel injection, a redesigned, more compact full-featured enduro meter with higher contrast liquid crystal display, a new real-time fuel consumption meter with low fuel warning light, aluminum side stand, sealed O-ring chain and 18-inch rear wheel are all standard equipment.

The front-positioned intake and rear-positioned exhaust layout deliver the widest spread of reliable power while balancing the weight for excellent mass centralisation.

The 2021 WR450F is designed to appeal to those born to ride, from professional enduro riders to super-capable trail riders. The new model comes in the new Team Yamaha Blue colour scheme that echoes the YZ and FX models also in the VictorYZone.
