2027 Honda CRF450X Red

Off-road starts here

When the terrain gets rough and the miles keep adding up, the CRF450X is in its element. With bold new HRC-inspired styling for 2027, it combines race-proven performance, off-road precision, and long-haul durability in one purpose-built package. Equipped with a wide-ratio six-speed gearbox, 18-inch rear wheel, and California Green-Sticker compliance, it’s ready for everything from wide-open desert to tight singletrack.

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.

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.

18-inch rear wheel

The 18-inch rear wheel provides a great selection of off-road tires, and the black DID rims look great too.

Features May Include: 

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.

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 and is wider than the standard MX frame to accommodate the six-speed transmission.

Dunlop MX52 tires

• Dunlop’s MX52 tires provide excellent traction across various terrains and conditions, making them ideal 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 improved handling are thanks to the compact twin-piston front brake caliper, anodized aluminum brake pistons, and a lightweight 260mm front disc that minimizes 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 offers a great selection of off-road tires, and the black DID rims enhance 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 desert rips.

Tuned-weight crank

• The bike has a unique crankshaft that differs from our MX and dual-sport models. The crankshaft's weight and inertia play a significant 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 positioned in front of the engine, between the frame downtubes, to improve the 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 offers the engine and lower-frame protection that serious riders demand on a machine like this.

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.

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.

Gear-driven counterbalancer

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

California Green-Sticker compliant

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

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 mileage and consumption, and can show data in miles or kilometers. It's in the same digital display as the speedometer 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 all conditions.
