Rekluse Core EXP 2.0 Clutch KTM 250/300 06-12
Rekluse Core EXP Clutch KTM 250/300 SX/XC/XC-W 06-12
EXP 2.0 includes a new EXP assembly that is made out of durable 7075 aluminum. This offers more rigidity and durability and does not require the hard anodizing process. New ball-wedge design offers unprecedented response and performance. New ¼ turn pins allow for quick and easy adjustments.
Rekluse introduces an all new type of clutch system that can be configured in two different operating modes: manual mode or anti-stall mode. The Rekluse Core Manual Clutch consists of a center clutch, a matched set of steel drive plates, springs and a manual pressure plate. The Rekluse Core EXP Clutch consists of a center clutch, a matched set of steel drive plates, springs, an EXP friction disk and an EXP pressure plate. All Rekluse Core Clutches work with your bike's stock friction disks or Rekluse friction disks. One of the primary benefits to the Rekluse Core Clutch is the ability to change from anti-stall mode (Core EXP Clutch) to manual mode (Core Clutch) in a matter of minutes.
The Rekluse EXP Pressure Plate and EXP Friction Disk transforms the Rekluse Core into a clutch that automatically disengages at idle, preventing accidental engine stalls while maintaining the clutch lever modulation and feel of a best-in-class manual pressure plate. Forget everything you’ve ever thought or heard about a centrifugally-actuated clutch: the Rekluse EXP changes the rules for a high performance clutch.
The Rekluse Core EXP is an entirely new type of clutch. The Core EXP Clutch was designed from the start for riders that demand the feel and control of a manual clutch lever coupled with the benefits of a clutch that won’t allow the motor to stall. Forget what you know about automatic clutches, the Rekluse Core EXP sets a new standard for how a clutch can improve your riding.
What if your clutch was smart enough to automatically disengage itself in a fall? Or in that rutted corner where you lost balance and couldn’t get on the clutch lever quick enough before the engine stalled? How many times has a stalled engine cost you valuable positions in a race? At the top level of Supercross and Motocross, riders are frequently seen kicking their bikes back to life as they lose valuable positions in a race. No rider—no matter how skilled—is immune to engine stalls with a traditional clutch.
Here’s what makes Core EXP unlike any clutch before it:
- Engine will not stall from a suddenly stopped rear wheel -
The Core EXP will automatically disengage the clutch at idle speed. Stomp on the rear brake as hard as you like, from any speed in any gear; the engine will not stall. The engine will not stall from the rear wheel being stopped in a crash. Get back to your bike, pick it up (no need to grab the clutch lever first) and go.
- Consistent clutch lever feel, regardless of RPM -
With prior centrifugal clutches, the effort at the clutch lever to disengage the clutch varied from low RPMs to high RPMs. The Core EXP clutch lever has a consistent disengagement effort, virtually the same as stock, regardless of engine RPM.
- Consistent clutch modulation—equal to or better than stock -
With prior centrifugal clutches, the clutch release mechanism acted directly upon a centrifugally actuated pressure plate. The centrifugal pressure plate was typically much stiffer than the stock pressure plate resulting in a "grabby" clutch engagement at high RPMs. At low RPMs, the centrifugal mechanism made it difficult to accurately override the clutch engagement. The Core EXP uses a six spring pressure plate similar to what's already in your bike. To get clutch modulation like a traditional manual clutch, the pressure plate needs to be structurally similar to a traditional clutch. The Rekluse Core EXP Clutch is the only anti-stall clutch with this similar structure providing consistent clutch modulation that is equal to or better than stock.
- Very aggressive clutch engagement -
Traditional centrifugal clutches are "tuned" to provide a limited amount of clutch slip in the lower RPM range. Low RPM clutch slip is best for technical off-road or very slick conditions. The Core EXP clutch is tuned to engage much more aggressively to better take advantage of high-traction soil conditions and shift the control of lower RPM clutch slip to the rider. An optional tuning kit is available from Rekluse to allow the Core EXP clutch to provide clutch slip at lower RPMs.
- Converts to a manual clutch in minutes -
With the Manual Mode Add-on Kit, the Rekluse Core EXP Clutch can be converted from a centrifugally actuated anti-stall clutch to a manually controlled clutch in just minutes. By swapping the Rekluse EXP pressure plate and EXP friction disk for the manual pressure plate and a stock friction disk, the clutch is converted to full manual control in a few minutes time.
- Directed Internal Oil Flow – To maximize the cooling effect in the clutch, oil needs to move from the inside of the clutch, through the clutch plates and out. The Rekluse Core EXP Clutch captures oil and feeds it to channels within the center clutch and then evenly distributes the oil to the clutch plates to maximize the cooling effect. Oil "dams" are used in critical places to prevent oil from "spilling" out of the clutch before the oil has a chance to cool the clutch plates. Net Result: Cooler clutch provides consistent action during hard use, increases overall clutch durability and improves clutch plate life.
- CNC Laser Cut Drive Plates with Continuous Radius Spline – Most OEM and aftermarket drive plates are stamped. Although metal stamping is a lower-cost process to produce a drive plate, it results in a drive plate of far less precision than a CNC laser cut drive plate. Rekluse CNC laser cut drive plates are made to much tighter tolerances than traditional stamped drive plates. Tighter tolerances mean less hammering on clutch components.
Furthermore, the Rekluse Core Clutch utilizes a full radius tooth profile for torque transfer between the drive plates and center clutch. A full radius contact between the drive plate and center clutch results in the load of the clutch being distributed more evenly over a greater surface area than is found in most OEM tooth patterns, resulting in less wear on the clutch components. Net Result: Longer clutch component life, smoother clutch engagement/disengagement.
- Steel Drive Plate at Top and Bottom of Clutch – Most OEM and aftermarket clutches are configured so that a friction disk wears against the center clutch and the pressure plate. Over time, the friction disk rubbing against the soft aluminum will cause premature wear of the part; even on hard anodized billet parts. The Rekluse Core EXP Clutch incorporates replaceable steel wear plates at the top and bottom of the clutch pack, protecting the expensive billet parts from friction disk wear. Net Result: Longer clutch component life, smoother clutch engagement/disengagement.
- Precision 17-7 Stainless Steel Clutch Springs – The Rekluse Core clutch includes a set of precision wound, heat-treated stainless steel springs. Heat-treated stainless steel provides superior resistance to “sacking” from high heat cycles over OEM clutch springs. Net Result: Longer clutch plate life from consistent clamping force.
- Spring Locating Pockets – The Rekluse EXP Pressure Plate includes spring locating pockets and custom spring bolts to center and hold each spring away from the sidewalls of the pressure plate. In OEM clutches without spring locating pockets and custom spring bolts, the pressure plate springs may rub on the side of the pressure plate, negatively affecting clutch disengagement/engagement and increasing wear. Net Result: Longer clutch component life, smoother clutch engagement/disengagement.
