What is an Automatic Clutch?
Core EXP, EXP and z-Start Pro are all auto-clutches. An Auto-Clutch is a centrifugal force actuated clutch that automatically engages and disengages the clutch in relation to RPMs. The Auto-Clutch automatically feeds out the clutch in the same way you feed out the clutch lever when starting from a stop. The rider only needs to turn the throttle to increase RPMs, to engage the clutch and go. It is not an automatic transmission, you must shift the gears. The benefit is that the auto-clutch will do the “feed” automatically and consistently, allowing you to be free to focus on other aspects of your riding. All three Rekluse Auto-Clutches allow retention of one’s clutch lever to manually override the auto-clutch at all times. As with any standard clutch, the rider can still “feed”, “fan”, “slip” or “pop” the clutch and do motocross style starts. Rekluse Auto-Clutches are performance enhancing for full sized bikes and ATV’s. See Performance for more info.
How will it affect my riding?
Rekluse Auto-Clutches make it easier to go fast, instill confidence and tame the gnarliest terrain. The auto-modulation of the clutch increases traction and virtually eliminates engine stalling. All this leads to more fun, easier to ride and increased rider performance. For the motocross racer the bottom line is that you will improve your lap times. You will put down better traction, leading to more efficient and ultimately faster cornering. By decreasing wheel spin and increasing traction, your launches off the line will improve substantially--putting you at or near the front of the pack. For the off-road racer, you will be able to navigate technical sections much easier than before. Rekluse Auto-Clutches eliminate the necessity of modulating the clutch in tight terrain, which will allow you to concentrate on the terrain in front of you. This will enable you to get better traction and develop better throttle control. Plus--because the Rekluse Auto-Clutches disengage when your engine speed drops to idle--stalling will be a thing of the past. You'll be able to ride longer, faster, and with less fatigue than ever before.
Can I still use my clutch lever like normal?
Yes. All three Rekluse Auto-Clutches allow retention of one’s clutch lever to manually override the auto-clutch at all times. As with any standard clutch, the rider can still “feed”, “fan”, “slip” or “pop” the clutch and do motocross style starts.
Do I have to use the clutch lever?
You have the option of using the clutch lever at any time, but it is not necessary. Some riders find that they rarely use the clutch lever to override the Auto-Clutch and choose the Rekluse Brake Kit. The Rekluse brake kit replaces the clutch lever with a left hand brake lever to actuate the rear brake. Note some models come with a 2-Finger Override lever to retain the clutch override feature.
Is it adjustable?
Yes. All three Rekluse Auto-Clutches are adjustable to suit rider preference and conditions. The stock set-up is what we have discovered to be the best setting that will satisfy most riders. However, you may refer to your Owners Manual or Tuning Guide to adjust the settings to your liking by changing springs, wedges and idle speed.
How does it work?
A traditional manual clutch uses springs to push a pressure plate into the clutch disks to keep the clutch always engaged until the rider pulls in the clutch lever. Pulling in the clutch lever pushes the pressure plate away from the clutch disks to manually disengage the clutch. An automatic clutch keeps the pressure plate away from the clutch disks when the engine is off or at idle. When the throttle is applied and the engine speed increases, a centrifugal device within the clutch expands, engaging the clutch disks.
Can I bump-start with an auto clutch?
All three Rekluse Auto-Clutches can be configured to bump-start the engine in the event your normal starting system fails. However, they can not be configured for bump-starting on the go like a standard clutch. One must stop the motorcycle and make an adjustment (on some Rekluse models this requires tools) to bump start and then make another adjustment to continue riding once the engine fires. Bump-starting can be done to get you home.
Do I have to modify my existing clutch parts?
No modification of your existing clutch parts is necessary with any of our current Rekluse clutches.
Can I go back to a stock setup?
Yes, due to the fact that no modification to your existing clutch parts is necessary. Generally, you can return a bike to stock manual set-up in about 30 minutes. With the addition of a manual mode pressure plate, the Rekluse Core EXP can be converted from auto to manual mode and back to auto mode in 5 to 10 minutes.
