450cc Unicam® engine
In the off-road world, weight management is king. That is why we fitted the CRF450X with our Unicam® engine. The included valve angle flattens the combustion chamber, making it more compact and lowering the center of gravity.
Full lighting package
Whether you’re winning WORCS races or dominating the Baja 1000, you’ll need good lighting. We fitted the CRF450X with a full lighting package (headlight and taillight) for improved visibility in low-light conditions.
Factory handguards
Protection is paramount when taming tough trails. For this reason, we fitted the CRF45OX with factory handguards. These guards protect against rocks, branches, thorns, and brushes while giving the bike a polished look.
Engineered for the extreme
450cc Unicam® engine
Honda's Unicam® design creates a compact engine that saves weight. The included valve angle flattens the combustion chamber for easier ignition while the camshaft sits lower, making it more compact and lowering the center of gravity.
Wide-ratio six-speed transmission
Having six speeds in the transmission, as opposed to a typical five on an MX bike, provides more versatility. This bike can handle everything from east-coast rock crawling to wide-open Baja blasts.
Electric start
The electric start system ensures trouble-free starting. It drives the clutch side of the crankshaft, providing superior lubrication to starter gears while allowing a narrow engine with a short, strong crank.
Twin-spar chassis
The motorcycle has a lightweight, stiff, twin-spar aluminum chassis with excellent handling. It is wider than the standard MX frame to fit the six-speed transmission.
New graphics, same grit
Fuel injection
Our proven fuel injection system provides excellent torque, spot-on metering, and response, especially in the critical low-rpm range. Additionally, it automatically compensates for changes in elevation and weather.
Dunlop MX52 tires
The Dunlop MX52 tires provide excellent off-road traction across various terrains and conditions, making them critical for on- and off-road bikes.
Works-style front brake
Improved stopping power and handling thanks to the compact twin-piston front brake caliper, anodized aluminum brake pistons, and lightweight 260mm front disc that minimize unsprung weight.
18-inch rear wheel
The 18-inch rear wheel provides a great selection of off-road tires, and the black DID rims add to the aesthetic appeal.
Titanium fuel tank
The premium titanium tank is durable and lightweight, with a capacity of 2.0 gallons.
Skid plate
The factory skid plate is light, yet it also offers the engine and lower-frame protection that serious riders demand on a machine like this.
Sidestand
A sidestand may seem insignificant, but this forged alloy piece is an exceptional example of this bike's attention to detail.
Lighting package
It has a complete lighting package (headlight and taillight) for improved visibility in low-light conditions.
