engine & drivetrain

450 cc Unicam Engine

Honda Unicam cylinder heads combine the best of single- and double-overhead-cam designs. The configuration contributes to a compact engine that saves weight over a comparable dual-overhead-camshaft motor and also permits a narrow included valve angle. This flattens the combustion chamber to facilitate ignition flame propagation, allowing a high compression ratio. Since less space is taken up in the cylinder head, the camshaft sits lower in the head for a more compact engine and a lower center of gravity.

Smoother Airflow

To help the CRF450RX breathe more freely, engineers redesigned the entire air-intake system. A new airbox, new filter position, and new intake funnel combine to reduce restrictions to airflow. The result? Better throttle control and more consistent power delivery.

Revised Exhaust

In combination with its less-restrictive air-intake system, the CRF450RX’s revised exhaust with straighter airflow means smoother engine operation in the mid- to high-rpm range and more-controllable acceleration.

Hydraulic Clutch

Big power requires a strong clutch, and this bike delivers with a smooth-operating hydraulic clutch. Ditching the cable improves consistency, control and feel at the lever. The clutch capacity is generous, along with an extra plate and spring to maximize power transfer and durability.

Engine Mode Select Button

This simple handlebar-mounted button lets you dial in engine power-delivery character with a push of your thumb. Choose between Standard, Smooth and Aggressive, depending on track conditions.

Honda Selectable Torque Control (HSTC)

Honda Selectable Torque Control (HSTC) works to minimize rear wheel spin (thus wasted forward drive) and maximize traction. It doesn’t use a wheel-speed sensor, and, importantly, maintains feel at the throttle while managing power — ignition timing and the PGM-FI system are adjusted when the rate of change of rpm goes over a set amount. With three settings plus off to choose from, you can have your bike dialed no matter how much traction there is.

HRC Launch Control

We’re talking about a special ECU program here: push the button to select the mode, hold the throttle open, release the clutch, and the bike will do the rest, launching you into the first turn with a big advantage.

New ECU Settings

Our engineers never stop searching for ways to make it easier to go faster. Revised ECU settings combine with the other chassis and powertrain improvements to make the CRF450RX an all-around better performer.

chassis & suspension

New Aluminum Fram

The CRF450RX’s aluminum frame has been radically improved for 2025 with the aim of increasing rigidity and stability. Using 70% new components, Honda engineers have managed to improve torsional and lateral rigidity in every direction, resulting in more-controlled and predictable handling—particularly in rough conditions.

Improved Showa Fork

To complement the new frame, the CRF450RX also boasts an extensively revised Showa spring fork. Everything from the outer tube to the axle was rethought and redesigned, resulting in improved low-speed damping, reduced friction, and enhanced rigidity. It all adds up to better control and lower lap times.

Easier Shock Access

When you’re riding, you’ll appreciate the revised Pro-Link rear suspension with a new link system that’s less prone to flexing, and the redesigned shock with smoother action. When you’re wrenching, you’ll love the new ease of access to the rear suspension assembly. Removing the shock used to take about 21 minutes, by our watch, but can now be done in about 9 minutes. No more removing the seat, muffler and rear frame.

Single-pipe Exhaust

The CRF450RX uses a single-pipe header. It routes close to the center of the bike, and its light overall construction helps improve weight distribution. The single muffler uses a pressed-alloy design that lets us shape the muffler body for better rider ergonomics and lighter weight.

Large Front Brake

The large front-brake disc measures a whopping 260 mm, giving you superior stopping power while also being easy to modulate.

Black Rims

They may not help you go faster, but the black D.I.D® rims sure look good.

additional features

High Capacity Resin Fuel Tank

For longer cross-country loops, the CRF450RX features a bigger fuel tank that holds a full 8 litres.

Electric Start

Kickstarting? Maybe if you’re riding in the vintage class, but not here. By ditching the kickstarter entirely, our engineers were able to make a light bike even lighter. Electric starters and lithium-ion batteries are now so light and so good that putting them on a bike like this is a win/win combination. And winning is what the CRF450RX is all about.

Hand Guards

When the going gets extra tough, you’ll appreciate the hand guards on the CRF450RX.

Easier Filter Cleaning

Because the CRF450R’s air filter has no rubber gasket where it interfaces with the intake boot, cleaning and servicing the filter is faster and less messy.

Cool Running

Another way the CRF450R keeps its cool: a large radiator, with fins that are angled for efficient airflow.
