DIALED FROM THE START
It’s every dirt rider’s dream: a bike with the power, light weight, and crisp handling of a factory motorcrosser, but with the fine tuning that makes it perfect for rides outside the track. And hey, it’s our dream too—which is why we build the CRF450RX.
With all the updates of the 2023 CRF450R we’ve given it the magic touches that turn it into the perfect off-road enduro ride. In fact, things that make our 2023 CRF450R even better—like more low- and midrange torque—really take the RX to the next level.
Other RX differences? Our Honda Selectable Torque Control lets you maximize available traction under different conditions. A lightweight chassis, 18-inch rear wheel, hydraulic clutch and special suspension settings help you take on varied terrain. And then there’s the big feature nobody can touch: our reputation for quality and reliability.

Features

Fuel Tank
Stopping for fuel in a race costs time. With the CRF450RX’s 8.5 litre fuel tank, depending on the course and how much roost you’re making everyone else eat, it’s possible to make it through a three-hour enduro with just one fuel stop.

New Aluminum Frame
Our twin spar aluminum frame positions the rear shock’s mounting point low, opening up the airbox area and contributing to a lower center of gravity. The frame geometry also helps give you more traction, and that means more holeshots!

18-Inch Rear Wheel
An 18-inch rear wheel is another indication of the CRF450RX’s off-road heritage
