Tame the trees

Light, narrow frame

Starting with a superior frame, the chassis was designed to be narrow, lightweight, and more responsive due to reduced lateral rigidity. This results in a bike that is faster to get into, around, and out of corners.

Hydraulic clutch

This bike has a hydraulically actuated Nissan 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.

Airbox and filter

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

Dunlop Geomax AT81 tires

The Dunlop Geomax tires are specifically designed for Enduro use. The AT81 tires are spec'd at 21 inches for the front and 18 inches for the rear.

New chassis

For 2025, our latest generation frame is lighter than the previous one, with approximately 70 percent new frame components for better compatibility with the new suspension. We achieved this by making the main spars narrower, which also improves the responsiveness.

New tripleclamps, axle, and steering stem

The 2025 model features new triple clamps, a revised fork, and a new front axle and steering stem. These components work together to improve rigidity, responsiveness, and turning performance.

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. For 2025, new springs, seals, and valves improve the consistency of the stroke feel throughout the entire range of travel.

260mm front brake

The large front brake disc measures a whopping 260mm. It offers great brake feel and a pattern that reduces weight. Front and rear brake-disc guards are also part of the package. This year, a new caliper reduces the lever fade and provides a better brake feel.

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.

Honda Selectable Torque Control (HSTC)

Changing terrain requires changing power character. 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.

Engine mode button

This simple handlebar-mounted button lets you dial in the engine power delivery character with a thumb push. Choose Standard, Smooth, and Aggressive, depending on track conditions or rider preference.

Fresh styling

The 2025 model has new graphics inspired by HRC works bikes. It features our "in-mold" graphics, designed to remain durable after repeated track sessions and cleaning.

New radiator shrouds

Using Computational Fluid Dynamics, we redesigned the radiator shrouds to increase cooling. This improves power consistency and endurance during a race, especially when the engine is pushed hard.

Flat seat/tank junction

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

Electric start

We're ditching the kickstarter on the bike to make it lighter. The bike now uses an electric starter with a lithium-ion battery, resulting in better performance.

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.
