2020 Honda CRF450X Features and Benefits

Posted on May 7, 2019 by The Dirt Bike Guy.

Today Honda announced information and specs regarding the 2020 CRF450X. With wins in 21 of the last 22 Baja 1000s (including 12 with the CRF450X), it's no secret that Honda rules the legendary off-road race, and in the Baja debut of the model's new iteration, SLR Honda kicked off the 2019 SCORE International series with a win in the San Felipe 250. A true off-road machine, the CRF450X is 50-state off-road legal and is suitable for year-round racing and trail riding. With off-road appropriate features like a sidestand, 18-inch rear wheel, headlight, sealed chain and six-speed transmission, it's ready for desert expanses or tight woods, and it gets new graphics for the 2020 model year.
