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, you need a specialised machine... a machine like our CRF450RX. You'll get the power, agility and precise handling of a factory motocrosser, with the ruggedness and specialised suspension you need to conquer wide open riding.
For the new model, 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.
We've carefully tuned the frame’s rigidity balance to factory rider spec, to boost corner speed over rough, torn up track conditions and improve high-speed stability.
Features
Redesigned SHOWA™ Rear Shock & Pro-Link
Rebuilt to match the new chassis, the rear shock is tuned for uniform reaction anywhere in its stroke. It operates through an 11% more rigid Pro-Link structure tuned for smoother bump control.
Swingarm
The swingarm uses a special fabrication technique that lets us fine-tune the flex to work with the chassis and give you better rear traction and cornering precision.
260mm Front Brake
The large front brake disc measures a whopping 260mm. It offers great brake feel and a pattern that reduces weight. Front and rear brake-disc guards are also part of the package. This year, a new caliper reduces the lever fade and provides a better brake feel.
449cc Unicam® Engine
Honda's Unicam® cylinder heads combine single- and double-overhead-cam designs to create a compact engine with a narrow valve angle. This allows for a higher compression ratio and lower center of gravity.
New Tripleclamps, Axle, and Steering Stem
The 2025 model features new triple clamps, a revised fork, and a new front axle and steering stem. These components work together to improve rigidity, responsiveness, and turning performance.
New Radiator Shrouds
Using Computational Fluid Dynamics, we redesigned the radiator shrouds to increase cooling. This improves power consistency and endurance during a race, especially when the engine is pushed hard.
Airbox and Filter
The air filter and airbox shape improve torque delivery. The filter can be accessed through the left number plate, and the intake boot's filter interface has no rubber gasket, making it easier and less messy to clean and service.
Selectable Engine Modes
This simple handlebar-mounted button lets you dial in the engine power delivery character with a thumb push. Choose Standard, Smooth, and Aggressive, depending on track conditions or rider preference.
Honda Selectable Torque Control
Changing terrain requires changing power character. 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 color-matched to your new bike, and are even vented.
Cross Country Tyres
The CRF450RX tyres, 90/90-21 at the front and 120/90-18 at the rear, are specifically designed for enduro use, so you can ride the way you want, where you want.
Large Fuel Tank
Large plastic 8L fuel tank, ideal for cross country rides, lets you keep riding for longer.
Showa® Spring Fork
The 49mm Showa® fork is specially tuned for off-road racing and features a conventional spring design that helps increase front-suspension precision, handling, and feel. For 2025, new springs, seals, and valves improve the consistency of the stroke feel throughout the entire range of travel.
