New styling
The graphics of the X-model bikes are inspired by our MX models. For 2027, we have introduced bold, horizontal Honda and CRF logos, along with blue side panels and a rear fender for a unified HRC racing look. The smooth bodywork allows for easy movement, and the in-mold graphics ensure durability.
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.
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.
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.Born for open and fast
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
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.
