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.
Installation / Maintenance
How hard is it to install?
The rule of thumb is that if you can change out your clutch plates, you can install any of our Rekluse clutches. Detailed instructions are provided with each kit and we have installation videos on our website. Technical Support is available Monday-Friday from 8:30am -5:00pm Mountain Time.
Will an auto clutch wear my parts faster?
No, Rekluse clutches are more efficient at clutching than the human hand, which means your clutch parts will last as long or longer than a conventional clutch.
What maintenance is required?
Periodic check of your Installed Gap is necessary with your Rekluse clutch. This is a simple process that differs by model, but does not take more than 10 minutes with any Rekluse Clutch. View maintenance videos on our website.
What is an installed gap?
Installed gap on z-Start Pro Clutches is the measurement between the pressure plate and the top friction plate. This can be measured with the provided no-go gauges placed 180° (directly across from each other). One gauge should slide in easily the second gauge should not slide in. Don’t not use excessive pressure when inserting the no go gauges. This can also be checked with two feeler gauges used in the same manner as the no-go gauges. The measurement needs to be 0.030- 0.045 inch. (.0762mm – 1.143mm)
How much weight does it add?
Depending on the model, between 4 ounces and 12 ounces. Because clutch components spin much slower than the flywheel, there is little or no "flywheel" effect created with a Rekluse clutch.
What oil do you recommend?
Let's start with oils we do not recommend. Any oil formulated for automotive use is not recommended and in general, should not be used in motorcycle applications. This includes conventional and synthetic oils formulated for automotive use. Modern automotive oils do not contain the anti-wear additives necessary for proper lubrication in a motorcycle engine and may contain high quantities of friction modifiers that can cause excessive clutch slip. That said, in most cases the oil you use should work fine in all Rekluse clutches However, some riders may find they experience clutch squeal, clutch chatter or have problems with clutch slip. If you experience these problems, we recommend trying Shell Rotella T, a heavy-duty, conventional diesel engine oil.
At Rekluse, we have found Shell Rotella T (15W-40) provides excellent clutch performance and often eliminates customer complaints of clutch problems. Why do we recommend conventional diesel engine oil over synthetic? In general, we have found conventional oils perform slightly better at reducing clutch noise vs synthetic oils. However, many Rekluse customers get excellent performance with synthetic oils.
The bottom line: If your current oil is working fine, keep using it. If you're hearing some clutch noise or your clutch feels soft or slips, give the Shell Rotella T a try.
Myth – Freewheeling into corners
Fact – A properly set-up Rekluse Core EXP clutch does not freewheel into the corners. Some riders, specifically at sand tracks, prefer to adjust their Rekluse Core EXP to free wheel like a 2-stroke. The clutch is fully adjustable and the standard out of the box set-up is stock-like engine compression braking.
Myth – You can’t do a regular motocross start with an auto-clutch
Fact – Rekluse Core EXP allows the rider to start exactly the same way they would with a stock clutch. With Rekluse Core EXP, you have the benefit of full manual clutch override. The clutch lever feels and functions just like your stock clutch lever and can be pulled in at full throttle on the starting line and manually modulated off the line.
Myth – Auto-clutches are for beginners or those with low skill levels
Fact – The Rekluse Core EXP auto-clutch has performance benefits that appeal to virtually every rider and racer. Rekluse Core EXP has competed in the highest level of professional motocross, Supercross and offroad racing world-wide. See Racer testimonials.
Myth – You can’t bump start an Auto-clutch
Fact – This is true in the sense that you cannot bump-start a motorcycle equipped with a Rekluse Auto-Clutch like you would typically do with a manual clutch. However, 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.
Myth – You don’t shift gears with an Auto-Clutch it’s like an automatic transmission.
Fact – Rekluse Auto-Clutches automatically engage and disengage clutches not transmissions. One must shift the gears up and down just like in a motorcycle with a manual clutch. What is automatic, is the clutch feed and modulation to lock out (full engagement) and the disengagement (to prevent stalling). The rider doesn’t have to manually modulate the clutch lever as this is automatic. However, all Rekluse Auto-Clutches have the manual clutch lever override feature allowing the rider the choice to use the clutch lever or not.
