UNLEASH YOUR OFF-ROAD DREAMS.

Imagine the ultimate dream bike for dirt riders–a machine that combines the power, agility, and precise handling of a factory motocrosser with the finesse needed to conquer off-road adventures. That’s the 2025 Honda CRF450RX. We’ve taken all the remarkable enhancements from our 2025 CRF450R motocrosser and infused it with some engineering magic, resulting in the perfect off-road companion. You’ll experience increased low- and midrange torque through revised ECU and fuel injection settings, along with the enhanced usability provided by a wide-ratio five-speed transmission. But that’s not all: The RX showcases our extraordinary Honda Selectable Torque Control, empowering you to optimize traction in any scenario. Additionally, a lightweight chassis, 18-inch rear wheel, and specialized suspension settings are meticulously designed to conquer every terrain you encounter. And here’s the icing on the cake: our unrivaled reputation for quality and reliability. The CRF450RX is the genuine article, as any off-road rider will attest!

LIGHT, NARROWER FRAME
Great handling starts with a superior frame. The CRF450RX’s chassis was designed to be narrow, lightweight, and more responsive thanks to reduced lateral rigidity. The result is a bike that gets into, around, and out of corners faster.

NARROWER SWINGARM
Designed in conjunction with the frame, by using narrower main members (just like the frame uses narrower main spars), we’ve matched the swingarm’s lateral rigidity to the rest of the chassis. What you get is a balanced, fully integrated approach to frame stiffness, letting you get around corners faster and with a better feel.

HYDRAULIC CLUTCH
The CRF450RX includes the first hydraulically actuated clutch we’ve offered outside of our works bikes. Made by Nissin, it’s the same design as in our Grand Prix MX machines, and performs better than third-party conversions. You get a clutch-lever pull that’s ten percent lighter at its peak, even though it’s paired with a stronger clutch. Plus, you’ll never have to worry about making a clutch-cable adjustment, even during the longest events.

HONDA SELECTABLE TORQUE CONTROL (HSTC)
Changing terrain requires changing power character. No worries: The CRF450RX features our Honda Selectable Torque Control (HSTC). You can choose from one of three settings to perfectly dial your bike in depending on how much traction is available.

AIRBOX AND FILTER
The air filter and airbox shape are designed to help deliver more torque. You can access the airbox through the left number plate. And because the filter has no rubber gasket where it interfaces with the intake boot, cleaning and servicing the filter is faster and less messy than ever.

ELECTRIC START: Kickstarting? Maybe if you’re riding in the vintage class, but not here. By ditching the kickstarter entirely, our engineers can make the CRF450RX 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 CRF450RX is all about.

DUNLOP GEOMAX AT81 TIRES
The CRF450RX’s Dunlop Geomax tires are specially designed for Enduro use. The AT81 tires are spec’d at 90/90-21 for the front and 120/90-18 for the rear. You read that right: the CRF450RX rolls on an 18-inch rear wheel.

449CC UNICAM® ENGINE
Honda’s Unicam® cylinder heads combine the best 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.

SLIM BODYWORK
Narrow bodywork makes it a lot easier to move around on your bike and maximizes your riding freedom.

FACTORY HANDGUARDS
Fully integrated handguards attach right to the control-lever pivots, are color-matched to your new bike, and are even vented.
