THE DIRTBIKE YOU’VE ALWAYS DREAMED OF
Here’s a secret the best off-road riders know, and everyone learns eventually.
While motocross bikes are light and fast, they’re built for the track. When you’re riding off-road at a championship level, you need a specialized machine. . . .a machine like our CRF450RX.
You’ll get the power, agility, and precise handling of a factory motocrosser with the ruggedness and specialized suspension you need to conquer wide open riding.
For 2025 the RX gets all the changes we’ve given our CRF450R (new tank shrouds, new frame, new shock linkage, new front brake) and combines that with a close-ratio five-speed transmission, 18-inch rear wheel, Honda Selectable Torque Control and more.
All in all, it’s as unbeatable off-road as our CRF450R is on a Supercross or Motocross track. And that’s saying something.
Key differences between the “RX” has over the “R” model:
🔴 Larger fuel tank (8 vs 6.3)
🔴 Kick stand
🔴 18″ rear tyre (R has 19″)
🔴 51t rear sprocket (R has 50)
🔴 Softer suspension setting
🔴 Handguards
🔴 ECU settings
New for 2025:
🔴 Updated main frame constructed of 70% new components to optimize rigidity and improve handling characteristics.
🔴 New subframe mounting point optimizes lateral rigidity and reduces energy transmission from the rear of the bike to the front.
🔴 The rigidity of the steering stem, triple clamps, outer fork tubes and front axle have all been revised to match the frame updates.
🔴 The fork features new springs, kit-fork-inspired Bending Control Valves, seals and oil for a consistent feel throughout the stroke, while minimizing harsh feedback.
🔴 A new shock spring, reservoir, shaft and oil seal contribute to a consistent stroke feel to match the fork updates.
🔴 The linkage has been updated to a one-piece structure that enhances rigidity, to improve tracking and stability performance. It also features a new leverage ratio that decreases pitching while improving bottoming resistance.
🔴 The front brake caliper has an updated piston and seal grooves for consistent performance throughout the moto. It also features new machined accents.
🔴 The redesigned airbox provides a straighter pathway for airflow, improving throttle control and top-end power
🔴 The revised header pipe design is longer, creating more controllable power in the low-to-mid rpm range.
🔴 New ECU maps offer smoother delivery while retaining strong torque and power throughout the rev range.
🔴 The redesigned bodywork features smooth, flat surfaces to promote freedom of movement and offer a large contact point for gripping the bike.
🔴 Rear-shock removal time has been cut in half by eliminating the need to remove the subframe in order to access the shock.

Features
Fuel Tank
Stopping for fuel in a race costs time. With the CRF450RX’s 8 litre fuel tank, depending on the course and how much roost you’re making everyone else eat, it’s possible to make it through a three-hour enduro with just one fuel stop.
Frame
The redesigned mainframe is constructed from 70% new components, leading to a more comfortable and confidence-inspiring ride. An 8% increase in torsional rigidity improves overall stability while a 5% increase in the torsional/lateral rigidity ratio allows for precision cornering. Vertical torsional rigidity is increased by 4%, enhancing stability in rough track conditions.
Side Stand
The CRF450RX is also equipped with a forged-aluminum side stand for convenient on-trail parking.
