Yamaha announced a redesigned WR450F for 2021 along with a returning WR250F. They join the previously announced YZ450FX, YZ250X, YZ250FX and YZ125X in Yamaha’s 2021 cross country lineup.
2021 Yamaha WR450F

Yamaha updated the WR450F’s engine, frame, suspension and brakes with the goal of producing a lighter, more powerful and better handling enduro and trail bike.
The 449cc liquid-cooled, four-stroke, electric-start Single receives a new cylinder head with a reshaped combustion chamber and steeper valve angles. The compression ratio was increased to 13.0:1 from 12.8:1, and a new crankcase breather system was adopted to improve engine efficiency. The five-speed transmission was also further refined for smoother shifting. Yamaha claims the engine is lighter, more compact, and produces more power across the rev range. The aluminum bilateral beam frame has different wall thicknesses and flex characteristics to improve cornering, traction and bump stability. The 2021 WR450F receives new engine mounts, top triple clamp and front axle to reduce overall weight. The KYB suspension also received updates to its compression and rebound characteristics. Yamaha also added a redesigned front brake caliper, brake pads and front rotor.
Other updates include a more compact electric start system and an updated LCD screen that now includes a low fuel warning and a fuel consumption meter.
The 2021 Yamaha WR450F will be offered in Team Yamaha Blue for $9,799. Expect to see it in show...
