The Unicam® cylinder head offers a compact, lightweight design with a narrow valve angle, which improves combustion chamber efficiency, increases compression ratio, and lowers the center of gravity.

Torque output has been maximized with a unique airbox shape and filter design. The filter is easily accessible and features a gasket-less design for quicker and easier cleaning and servicing.

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.

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.

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) 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.

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.

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

The CRF450RX’s aluminum frame is engineered for increased rigidity and stability. Its structure enhances torsional and lateral stiffness in every direction, delivering more controlled and predictable handling — especially in rough conditions.

The CRF450RX features a Showa spring fork designed for optimal low-speed damping, reduced friction, and increased rigidity. From the outer tube to the axle, every component works together to deliver precise control and consistent performance — lap after lap.

The CRF450RX’s Pro-Link rear suspension is built around a link system that resists flex and a shock with smooth, consistent action. Maintenance is straightforward, with easy access to the rear suspension assembly. The shock can be removed in minutes — no need to take off the seat, muffler, or rear frame.

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

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

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