2021 Honda CRF450R Motocross Bike Revealed

Introducing the all-new 2021 Honda CRF450R motocross bike. The CRF450R receives a wide array of improvements and upgrades under a development theme of ‘Razor-sharp Cornering’. 2kg lighter, thanks to a revised frame and subframe. The new frame and swingarm’s rigidity balance, combined with tighter chassis geometry, heightened ground clearance and suspension changes, are all targeted at creating optimal cornering performance.

The engine also benefits from HRC’s strong focus on low to midrange torque. The decompressor has been relocated, airbox volume is up, the throttle body redesigned and exhaust ports reshaped. The exhaust downpipe is new and a single muffler replaces dual mufflers. A larger volume hydraulic clutch has an even lighter lever action, while other weight saving details include a smaller fuel pump and optimised magnesium cylinder head cover.
