Features may include:
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.
Chassis & Suspension

• New Aluminum Frame

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.
