Up your enduro game

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.

Up your enduro game

18-inch rear wheel

Designed for enduro use, the 18-inch rear wheel and tire combo provides better bump absorption and a broader contact patch to smooth out the roots, ruts, and rocks that come with off-road riding.

Up your enduro game

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. Plus, you won't need to make clutch-cable adjustments, even during long events.

Up your enduro game

Larger fuel tank

We gave the RX a bigger, 2.1-gallon resin fuel tank. This will allow for fewer fuel stops, which can save valuable time over the course of a longer enduro.

Showa® spring fork

The 49mm Showa^® fork is specially tuned for off-road racing and features a conventional spring design that helps increase front-suspension precision, handling, and feel.

260mm front brake

The large front brake disc measures a whopping 260mm. It offers great brake feel and a pattern that reduces weight, while the caliper is designed to reduce lever fade. A front brake-disc guard is also part of the package.

Honda Selectable Torque Control (HSTC)

Changing terrain requires changing power characteristics. No worries: This bike features our Honda Selectable Torque Control (HSTC). Depending on the available traction, you can choose from one of three settings to dial your bike in perfectly.

Airbox and filter

The air filter and airbox shape improve torque delivery. The filter can be accessed through the left number plate, and the intake boot's filter interface has no rubber gasket, making it easier and less messy to clean and service.

Black DID rims

The DID DirtStar rims are lightweight and strong, while the black color looks good and is easy to clean.

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.

Electric starter

To keep the bike light, our engineers use an electric starter with a lithium-ion battery.

Flat seat/tank junction

It features a smooth seat/tank junction. The superior ergonomics make moving forward and back on the bike easier, increasing your control.

Larger fuel tank

We gave the RX a bigger, 2.1-gallon resin fuel tank. This will allow for fewer fuel stops, which can save valuable time over the course of a longer enduro.

HRC launch control

This special ECU program allows you to select a mode, hold the throttle open, release the clutch, and let the bike do the rest. Trust us when we say it will give you a significant advantage as you head into the first turn.
