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.
Cross-country DNA
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.
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.
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.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
Low center of gravity
The Unicam® engine's compact design and our center-of-mass engineering reduce the bike's weight and improve handling.
Works-style front brake
Oversized fuel tank
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.
Superior ergonomics
Placing the rider’s legs at the narrowest part of the frame helps improve comfort and handling.
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.
