2026 Honda CRF 450X

Six gears. One mission: off-road dominance

Born in Baja. Built for everywhere else. The CRF450X delivers championship-level off-road performance with trail-tuned precision and proven durability. With its six-speed gearbox, 18-inch rear wheel, and California Green-Sticker compliance, it’s ready for everything from desert races to tight singletrack. If the trail doesn’t quit, neither will you.

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.

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.

Titanium intake and exhaust valves

Lightweight titanium intake and exhaust valves permit smaller valve springs, reducing overall engine height.

Twin-spar chassis

A lightweight, stiff, twin-spar aluminum chassis provides excellent handling while being wider than the standard MX frame to fit the six-speed transmission.

Dunlop MX52 tires

Dunlop’s MX52 tires provide excellent traction across various terrains and conditions, making them critical for on- and off-road bikes.

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

Increased stopping power and handling are thanks to the compact twin-piston front brake caliper, anodized aluminum brake pistons, and lightweight 260mm front disc that minimize unsprung weight.

Works-style rear brake

An HRC works-style rear brake system uses a 240mm brake rotor that integrates with the rear master cylinder and fluid reservoir, eliminating the need for a separate reservoir and hose.

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.

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.

Tuned-weight crank

The bike has a unique crankshaft that differs from our MX and dual-sport models. The crankshaft's weight and inertial characteristics play a big role in power delivery.

Dual radiators

The dual radiators feature a refined core for superior heat dissipation. At the same time, the coolant recovery tank is in front of the engine between the frame downtubes for an improved center of gravity.

Oversized fuel tank

We gave the X model a larger, 2.0-gallon resin fuel tank. This will allow for fewer fuel stops, which can save valuable time over the course of a long ride or race.

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.

Factory handguards

Designed exclusively for off-road riders and manufactured to Honda standards, these guards protect against rocks, branches, thorns, and brushes while giving the bike a polished look.

Works MX styling

If the X-model graphics remind you of our MX bikes, that’s because they're derived from them. The smooth bodywork makes it easy to move around, while the in-mold graphics are durable, too.

Gear-driver counterbalancer

The gear-driven counterbalancer reduces vibration and drives the water pump.

California Green-Sticker compliant

California riders can ride this bike off-road year-round in any open OHV area since it is Green-Sticker compliant.

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.

Fuel mileage meter

The fuel mileage meter is a key feature that displays current and average fuel mileage and fuel consumption and can show data in miles or kilometers. It's in the same digital display as the speedometer, odometer, tripmeter, and clock.

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.

Lighting package

It has a complete lighting package (headlight and taillight) for improved visibility in low-light conditions.
