2021 Honda CRF450R

Ssince its 2002 introduction, the CRF450R has become the benchmark motocrosser, and together with its limited-edition CRF450RWE sibling, it’s the top-selling 450cc MX model in the U.S. Nonetheless, Honda didn’t rest on its laurels for the 2021 model year, endowing the legendary machine with important updates aimed at improving power, handling and consistency. As usual, this model draws lessons from Honda Racing Corporation’s global race program. A production version of the factory machine campaigned by two-time World Champion Tim Gajser to the 2021 MXGP crown, and the basis for the motorcycle that Team Honda HRC riders Ken Roczen and Chase Sexton campaign this season, the 2021 CRF450R represents a significant step up from what was already an extremely capable race machine.

 

2021 Honda CRF250R

The machine that took Chase Sexton to the 2020 AMA 250SX East Region crown and Kyle Peters to the 2020 AMA Arenacross title returns for the 2021 model year, with strong power across the rev range and a low-center-of-gravity chassis layout that delivers nimble, stable handling. The CRF250R is the platform campaigned this year by Team Honda HRC riders Hunter and Jett Lawrence.
