Overview

Upgraded performance

The 2023 CRF450RX takes performance to the next level, thanks to several upgrades designed to boost low-end torque. The intake port is narrower, the air intake longer, the throttle bore now 44mm (down from the previous generation’s 46 mm) and the valve timing and springs have been updated. Combined, these improvements mean more low end torque and better response, meaning riders can maintain a taller gear, leading to less fatigue for riders.

Upgraded performance

The 2023 CRF450RX takes performance to the next level, thanks to several upgrades designed to boost low-end torque.

Hydraulic Clutch

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. Compared to the cable system of the previous generation CRF450R, the lever pull is 10% lighter, clutch capacity is increased by 27%, an extra plate and spring are added to maximize power transfer and durability and to top it off, clutch slip is reduced by 85% at peak power.

Electric Start

Kickstarting? Maybe if you’re riding in the vintage class, but not here. By ditching the kickstarter entirely, our engineers were able to make a light bike even lighter. Electric starters and lithium-ion batteries are so light now and so good that putting them on a bike like this is a win/win combination. And winning is what a CRF450R-series bike is all about.

Honda Selectable Torque Control (HSTC)

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.

HRC Launch Control

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.

Engine Mode Select Button

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.
chassis & suspension

Updated frame to ride faster with less fatigue

The 2023 CRF450RX is focused on being faster with less rider fatigue. They achieved this through updating the frame rigidity and the cilynder head hangers which works seamlesly with the updated suspension to improve traction, stability and bump absorption. Settings on the RX are optimized for comfort on longer rides and x-country specific terrain and obstacles.

Better Muffling, Stronger Body

Durability matters on the track, which is why the muffler is now made of stronger materials to prevent deformity, while its inner pipe has also been modified for better sound muffling – this without adding weight or sacrificing performance.
additional features

High-Capacity Resin Fuel Tank

For longer cross-country loops, the CRF450RX features a bigger fuel tank that holds a full 8 litres.

Hand Guards

When the going gets extra tough, you’ll appreciate the hand guards on to the CRF450RX.
