2021 Honda CRF450X Features and Benefits

When it comes to motorcycle racing in Baja, "dominant" doesn't quite do justice to Honda's record. Twenty-two of the last 23 victories in the legendary Baja 1000 have gone to Honda, including SLR Honda's convincing 2019 win, and 13 of those belong to the CRF450X. Not only does it rule desert racing, but the CRF450X is a great trail bike, thanks in part to its 50-state year-round off-road-legal status. With off-road appropriate features like a side stand, 18-inch rear wheel, headlight, sealed chain and six-speed transmission, it's ready for desert expanses or tight woods.

Sharing similar styling updates as its CRF Performance Line counterparts, the 2021 CRF450X features all-new graphics and handguards.
