2026 Honda CRF® 450R

2026 Honda® CRF450R

For over 50 years, the Honda CRF450R has been the benchmark of performance on the track—and it’s only getting better. This championship-proven 450cc beast delivers explosive low-end and midrange torque, giving riders the power to dominate corners and hold taller gears with total control.

Engineered for victory, its razor-sharp chassis delivers unbeatable stability, while precision-tuned suspension carves through tight lines with confidence. Add in a high-durability muffler that keeps things quieter and more efficient, and you’ve got a machine that’s built to perform—and built to win.

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 centre 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 CRF450R’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 CRF450R’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 CRF450R 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 CRF450R’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.
