Having featured heavily in Honda-mounted teams winning 20 of the last 21 Baja 1000s, the CRF450X gets a complete overhaul for 2019, injecting the DNA of the modern CRF platform into a true off-road machine suitable for year-round racing and trail riding. With off-road appropriate features like a sidestand, 18-inch rear wheel, headlight, and sealed chain, the CRF450X is ready for desert expanses or tight woods.

Honda's CRF450X has long been the choice of Baja champions and woods pros-and riders who want the light weight and awesome power of a premium MX bike, but who also know that while MX machines are perfect for 30-minute motos, out in the big, bad, open-class real world you need a machine that can do more. That all-around excellent performance is what's made the CRF450X always stand out, whether it's in the winner's circle in La Paz or out on your local trails. And for 2019, the CRF450X has been completely overhauled from the ground up-with lots of new upgrades, including an all-new aluminum frame and . . . wait for it . . . a six-speed transmission!
