Understanding Rekluse Automatic Clutches

Rekluse automatic dirt bike clutches have become increasingly popular across motocross and enduro riders, offering both performance and operational benefits that enhance the riding experience. You might be thinking about how these dirt bike clutches actually work, and if you should be installing one on your dirt bike.

What is a Rekluse automatic clutch?

Rekluse's range of aftermarket auto clutches automatically engage and disengage, yet still allows for engine braking and manual use of the clutch lever as well. They're designed to prevent stalling at low speeds, while it offers performance advantages in the fact that it automatically delivers traction to the rear wheel.

How does a Rekluse clutch work?

The workings of a Rekluse auto clutch are centred on an EXP disk, which is made up of wedges that are positioned around a clutch disk, and they’re designed to respond to differing engine speeds. When engine speed is increased and there’s greater centrifugal force, the wedges create an outward force on each half of the EXP disk, resulting in them expanding and ultimately engaging the clutch.

When the engine speed and centrifugal forces decrease, the wedges begin to retract and the EXP disk contracts, allowing the clutch the disengage.

The clutch is set up with a small gap between the clutch pack and pressure plate to ensure it disengages at idle. When the RPM increases above idle, the EXP disk expands and overcomes the gap, which then engages the clutch. This means the use of a clutch lever and normal clutch techniques are retained.

The Rekluse EXP disks are also tunable and can be set to engage at varying engine speeds, and how harsh or quickly the clutch engages can also be tuned.

How do I choose the right Rekluse clutch for me?

There are two main types of Rekluse clutches - the Core EXP 3.0, and the RadiusX.

The Rekluse Core EXP 3.0 clutch is a premium offering that's trusted by some of the world's best riders. The Core EXP 3.0 is essentially the full kit that includes the hub and pressure plate, where it's designed to utilise OEM frictions and Core technology to bring stock lever feel to an auto clutch system.

Key features of the Rekluse Core EXP 3.0 include:

• Complete auto clutch with manual override
• Prevents engine stalls
• Clutch lever use is optional and lever feel and function are unchanged
• Smooth power engagement increases traction
• Cooler operating temperatures and incredibly efficient clutching provide extended clutch life
• Allows riders to refine skills like precise throttle control, line selection, and cornering
• Proprietary billet components offer superior durability
• Riding is enhanced, more fun, and less demanding so riders can conquer more terrain
• Completely tunable

The Rekluse RadiusX is a more affordable option that combines the best of both worlds, as it uses Rekluse's TorqDrive technology with its flagship automatic EXP disk, yet it all works with your OEM clutch components, using your standard hub and pressure plate.

Key features of the Rekluse RadiusX include:

• On-the-fly external adjustment for cable models
• An automatic clutch that puts more power to the ground
• Improved torque transfer over OEM
• Reduced clutch fade
• Longer clutch pack life with less adjustment over time
• Custom basket sleeves dramatically reduce clutch wear and basket notching
• More direct connection to manipulate the motor’s horsepower by reducing free play
• Precise, consistent modulation and less action required to override the clutch

I ride motocross, how will a Rekluse auto clutch benefit me?

Rekluse clutches have become increasingly popular amongst motocross and supercross racers, and can be seen fitted on the bikes of some of the best riders in the world. An auto clutch can benefit motocross riders by allowing you to ride a taller gear through corners and applying the rear brake without the fear of stalling, plus it simplifies the use of the clutch that promotes focus on throttle control and line selection.

I ride enduro, how will a Rekluse auto clutch benefit me?

Rekluse clutches have always been a popular choice for off-road and enduro riders, as it makes for easier navigation of technical terrain and the automatic modulation of the clutch allows for better traction in slippery conditions. Steep and technical hills can also be negotiated without worrying about feathering the clutch to keep the RPMs up and the bike running.
