Enduro ace

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.

Enduro ace

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.

Enduro ace

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.

Enduro ace

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.

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.

Downdraft fuel injection

The bike features a downdraft intake tract and fuel-injection body to help increase both power and fuel-metering precision. It's part of the reason it offers such explosive power and massive torque.

Titanium intake valves

Lightweight titanium intake valves cut down on reciprocating mass and permit the use of smaller valve springs, reducing overall engine height and weight.

Honda Selectable Torque Control (HSTC)

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

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.

HRC launch control

This is a special ECU program that 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.

Showa^® spring fork

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

Triple clamps

New upper and lower triple clamps work in concert, helping improve and balance the bike's total rigidity, responsiveness, and turning performance.

Rear suspension

We've optimized the shape of the rear shock to match the new frame and gave it settings to work with the chassis that are designed for Enduro riding.

Skid plate

A factory skid plate is light and offers the kind of engine and lower-frame protection that a racer demands.

Slim bodywork

Narrow bodywork makes it much easier to move around on your bike and maximizes your riding freedom.

Seat accessibility

We moved the attaching bolts from the rear to the front and the tongue from the front to the rear. The result? When it's time for service, removing and re-installing your seat is easier than ever.
