Built on the same all-new platform as the 2027 CRF450R, the CRF450RX is engineered for off-road dominance. Specially valved Showa® suspension, an 18-inch rear wheel, and factory handguards help it take on demanding terrain with precision and control. And like its MX brother, it’s improved in every way: new engine, new frame, lighter weight, with power and torque tuned for the way riders actually ride, not just dyno charts. Finished in bold new red, white, and blue styling, its tri-color look proudly reflects the Honda HRC racing identity on which this off-road beast is built.
The complete redesign results in an engine that delivers 10.3 percent more peak horsepower, 3.7 percent more peak torque, and is 17mm narrower and is lighter than the 2026 model. The redesigned Unicam® valve layout that aligns intake and exhaust rockers on a common axis to increase valvetrain rigidity and create a more compact package.
Features
Rear Suspension
A lighter shock body is surrounded by a new red spring. The shock itself is more responsive, enhancing damping feel in the low-speed compression range and providing a more consistent feel throughout the suspension stroke.
Updated Swingarm
Check out the new swingarm. Meticulously hand-polished, the smooth step-free design and flawless welds elevate the bike’s appearance. The new throat-welded construction also helps reduce weight by nearly a pound.
260mm Front Brake
The large front brake disc measures a whopping 260mm. It offers great brake feel and a pattern that reduces weight, while the caliper is designed to reduce lever fade. A front brake-disc guard is also part of the package.
450cc Unicam® Engine
The complete redesign results in an engine that delivers 10.3 percent more peak horsepower, 3.7 percent more peak torque, and is 17mm narrower and is lighter than the 2026 model.
Renthal Fatbar
The Renthal aluminum Fatbar features a bend tuned for off-road riding, making it the new standard in excellence. You will love it!
One-piece Radiator Shrouds
Our engineers used Computational Fluid Dynamics to fine-tune the radiator shrouds for increased cooling efficiency. The one-piece design ensures consistent power output and prevents overheating.
Sealed Airbox and New Filter
The new airbox design has no separate lid, allowing you to access the air cleaner just by removing the sidecover. And for 2027, we’ve also changed both the air filter’s density and shape to reduce airflow resistance by approximately 10 percent.
Engine Mode Selection Button
Customize your engine's power delivery on the fly with the convenient handlebar-mounted button, allowing you to effortlessly switch between Standard, Smooth, and Aggressive modes to suit varying track conditions or rider preference.
Honda Selectable Torque Control
Changing terrain requires changing power characteristics. No worries: This bike features our Honda Selectable Torque Control (HSTC). Depending on the available traction, you can choose from one of three settings to dial your bike in perfectly.
Factory Handguards
Fully integrated handguards attach right to the control lever pivots, are colour-matched to the bike, and are even vented.
Dunlop Geomax AT81 tires
Dunlop’s Geomax AT81 tires are specifically designed for Enduro use. They are spec'd at 21 inches for the front and 18 inches for the rear.
Large Titanium Fuel Tank
Every gram counts, so we equipped the bike with a titanium fuel tank. It is light and strong, and thinner than our previous plastic unit, freeing up more space and helping to centralize the fuel's mass.
Showa® Spring Fork
Specially tuned for off-road riding, the new 49mm Showa® fork features Kashima coating to the internal sliding components, enhancing stroke feel and improving smoothness. A DBS (Dynamic Blow System) main-piston valve increases compression damping in the extremely low- to low-speed range, improving stroke consistency.
