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!
The CRF450X features an all-new six-speed gearbox for 2019. That extra cog gives you more choice, and makes this versatile bike even more versatile. Now you have a gear for everything from east-coast rock crawling to wide-open Baja blasts.
An electric start system ensures trouble-free starting in all conditions. The electric starter also drives the clutch side of the crankshaft to provide superior lubrication to starter gears while producing a narrow engine with a short, strong crank.
Honda’s Unicam cylinder heads combine the best of single- and double-overhead-cam designs. The configuration contributes to a compact engine that saves weight over a comparable dual-overhead-camshaft motor and also permits a narrow included valve angle. This flattens the combustion chamber to facilitate ignition flame propagation, allowing a high compression ratio. Since less space is taken up in the cylinder head, the camshaft sits lower in the head for a more compact engine and a lower center of gravity.
All new this year, the CRF450X uses a twin-spar aluminum chassis that takes advantage of all the lessons we’ve learned on the MX track and from winning countless Bajas. The frame is both light and stiff, and provides the basis for the CRF450X’s excellent handling. The chassis is also wider than the standard MX frame to accommodate the six-speed transmission.
