2025 Honda CRF450RX

2025 Honda® CRF450RX

Here’s a secret the best off-road riders know, and everyone learns eventually. While motocross bikes are light and fast, they’re built for the track. When you’re riding off-road at a championship level, you need a specialized machine. . . .a machine like our CRF450RX. You’ll get the power, agility, and precise handling of a factory motocrosser with the ruggedness and specialized suspension you need to conquer wide open riding. For 2025 the RX gets all the changes we’ve given our CRF450R (new tank shrouds, new frame, new shock linkage, new front brake) and combines that with a wide-ratio five-speed transmission, 18-inch rear wheel, Honda Selectable Torque Control and more. All in all, it’s as unbeatable off-road as our CFR450R is on a Supercross or Motocross track. And that’s saying something.

Features may include:

• NEW FRAME

Great handling starts with a superior frame, and that’s one place where the CRF450RX chassis puts you out front. First, it’s light—over a pound and a half lighter than the previous generation’s. By making the frame’s main spars narrow, we save weight, but more importantly we make the chassis more responsive. This year approximately 70 percent of the frame components are new for excellent, responsive turning performance and to work with the new suspension.

• HYDRAULIC CLUTCH

The CRF450RX includes a hydraulically actuated clutch. 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.

• NEW AIRBOX AND FILTER

Refinements in both the airbox and air filter streamline airflow and improve throttle control and feel, especially in tight turns. You access the airbox through the left number plate, and because the CRF450RX’s filter has no rubber gasket where it interfaces with the intake boot, cleaning and servicing the filter is faster and less messy than ever.

• DUNLOP GEOMAX AT81 TIRES

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