2026 Honda CRF 450RX Single-Cylinder 449.8 - Jonesboro Cycle

2026 Honda® CRF450RX

Track built. Trail tuned.

Built on the race-proven CRF450R platform, the CRF450RX is loaded with off-road essentials like terrain-taming Showa suspension and an 18-inch rear wheel. From tight trails to wide open spaces, this bike delivers podium-grade performance with Honda’s signature durability. Fast. Tough. Ready for wherever the course takes you.

Features may include:

Performance

450cc Unicam® engine

Honda's Unicam® cylinder heads combine single- and double-overhead-cam designs to create a compact engine with a narrow valve angle. This allows for a higher compression ratio and lower center of gravity.

Decompression system

Compared to the previous generation, our engineers improved the motorcycle's auto-decompression hardware, moving it from the right side of the cam to the left. This results in less stalling at low rpms and better rideability, especially when turning.

Handling

Responsive frame

A superior frame is crucial for excellent handling, and the chassis delivers. It's lightweight and responsive, with narrow main spars, and was designed with direct input from Team Honda HRC riders.

Tripleclamps, axle, and steering stem

Compared to the previous generation, we revised the tripleclamps, frame, fork, and steering stem for improved chassis rigidity and responsiveness to give the bike better cornering feel.

Engineering

Hydraulic clutch

This bike has a hydraulically actuated Nissin clutch, which is the same design as our Grand Prix MX machines and has a ten percent lighter pull. You won't need to make clutch-cable adjustments, even during long events.

Style

Race styling

Like our factory racebikes, the CRF logo is stacked and features our "in-mold" graphics, designed to remain durable after repeated track sessions and cleaning.

Comfort & Convenience

One-piece radiator shrouds

Our engineers used Computational Fluid Dynamics to fine-tune the radiator shrouds for increased cooling efficiency. The one-piece design ensures consistent power output and prevents overheating.
