PUTTING THE ‘X’ IN CROSS-COUNTRY

When you discover the Honda CRF450X, you’ve found the deceivingly similar-looking cousin to the CRF450R motocrosser, but specifically designed for off-road and cross-country competitions like the renowned Baja 1000 and WORCs racing series. While sharing the impressive Unicam® engine architecture with the "R" model, the CRF450X takes it up a notch with a wide-ratio six-speed transmission, off-road-tailored chassis, and a host of specialized features. Picture an 18-inch rear wheel for improved tire choice, standard sidestand and hand guards, unique ECU and fuel-injection settings, larger fuel tank, durable skid plate, and more. No matter where your off-road adventures take you, the CRF450X guarantees the ultimate off-road experience, unleashing power and conquering trails like no other. And to top it all off, it’s California Green-Sticker compliant!

WIDE-RATIO SIX-SPEED TRANSMISSION
Having six speeds in the CRF450X’s transmission compared to an MX bike’s typical five gives you more choice, and makes this versatile bike even more versatile. You have a gear for everything from east-coast rock crawling to wide-open Baja blasts.
ELECTRIC START
An electric start system ensures trouble-free starting in all conditions. The electric starter also drives the clutch side of the crankshaft, which provides superior lubrication to starter gears while allowing a narrow engine with a short, strong crank.
450cc UNICAM® ENGINE
Our Honda 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.
TWIN-SPAR CHASSIS
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.
