Model Description

CRF450R – 50 Years in the making

We’ve been racing motocross for 50 years. The highs, the lows and everything in between, we have had it all and owned every moment. Winning at the weekend is what drives us. And winning is what’s created the new CRF450R and, for 2023 only, the CRF450R 50th Anniversary.

A very special bike marking 50 years of motocross racing.

More Acceleration Less Effort

So you can drive harder than ever, the engine is armed with narrower intake ports, a longer air funnel and smaller, 44mm diameter throttle body delivering higher-velocity air flow to create more torque and low-down power. New ECU settings and valve timing (straight from Tim Gajser’s #243 HRC machine) create a usable powerplant with Launch Control, HSTC and EMSB to put it completely at your command.

What Works For HRC Factory Racers Works For You

We never, ever stop pushing. That’s what it takes to fight at the front and the CRF450R is now easier to ride faster, for longer. Its lightweight aluminium frame features a new, factory-rider specification rigidity balance – from 2mm thicker front frame joints and upper shock mount – as well as new steel engine hangers producing a stable chassis that finds amazing front-end grip, yet steers razor-fast.
