2026 Honda CRF 450RX

Features may include:

Engine & Drivetrain

• Unicam Engine

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.

• Smoother Airflow

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.

• 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.

Chassis & Suspension

• Aluminum Frame

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.

• Showa Fork

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.

• Shock Access

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.
