Rekluse - RadiusCX 4.0 Clutch Kit

Rekluse – RadiusCX 4.0 Clutch Kit

Rekluse’s RadiusCX 4.0 is the new benchmark for auto clutch performance — combining next-generation engineering with proven durability and that unmistakable Rekluse feel. Designed for riders who want smooth, stall-free control without giving up precision, the 4.0 system brings major improvements in strength, cooling, and engagement. The new EXP 4.0 base material resists heat better than ever, maintaining consistency even under the extreme temperatures clutch systems generate in hard riding or racing.

The redesigned EXP bases add rigidity and strength for a more direct lever feel, while the friction pads now use Rekluse’s proprietary TorqDrive pattern for optimized oil flow and cooling. Inside, the EXP “wedges” have evolved from sliding Teflon contacts to a roller-pin design that reduces friction by 98%, giving you smoother engagement, better response, and stronger, more connected power delivery. When combined with Rekluse’s Core and TorqDrive technologies, RadiusCX 4.0 delivers a clutch experience that’s lighter, sharper, and more durable than anything before it.

Why We Like It:
Rekluse didn’t just update the clutch — they reinvented how it feels. The 4.0 version hooks up cleaner, pulls stronger, and stays consistent through brutal heat. The new rolling wedge design makes engagement smoother and more natural, and you can feel the improved connection at the lever. It’s the kind of upgrade that instantly builds confidence on the track or trail.

Why It’ll Work for You:
 If you ride technical terrain, race enduro, or just want more control with less fatigue, RadiusCX 4.0 changes everything. It eliminates stalling, lets you start and stop without touching the clutch, and delivers predictable traction in any condition. You can still use the clutch lever normally whenever you want, but most of the time you won’t need to. It’s a true performance system that improves control, saves energy, and helps you ride longer and faster with less effort.

What Does it do?
A Rekluse clutch is an automatic clutch system for your dirt bike that keeps it from stalling while making it easier to control. You can come to a stop or take off again without using the clutch lever, but you still shift gears just like normal. It’s not a fully automatic transmission—it simply handles the clutch engagement for you. That means no more constant lever work in slow, technical, or stop-and-go sections, but you can still pull the clutch anytime you want for a manual feel.

Inside, a special EXP disk reacts to engine speed. At low RPMs, it relaxes and separates the clutch plates so the engine can idle in gear without stalling. As you give it throttle, centrifugal force expands the disk and engages the plates, smoothly transferring power to the wheel. When you slow down, it slips automatically to match speed. You still use the shift lever to go up or down through the gears as you accelerate or decelerate, but the Rekluse manages the clutching part for you.

On the bike, it feels totally natural—just smoother and more forgiving. You can roll to a stop in gear, take off effortlessly, and ride tight terrain with less fatigue and better traction. It gives you all the control of a standard clutch without the constant handwork, letting you focus more on riding and less on worrying about stalling.
