It seems the people at Rekluse gave up developing an auto-clutch for Buell X-series because they did not feel there was a market. Anyone who has ridden a dirt bike with a Rekluse installed will tell you it smooths out power delivery and keeps the rear tire hooked up in loose conditions (unless of course you want to break it loose). Anyone who has ridden a Ulysses off road knows they love to dig holes on loose uphills and are constantly breaking the rear tire loose when you don't want it to, the Rekluse would also help compensate for the tall first gear. So my question is: How many Uly owners would pony up for a Rekluse if it were available? http://www.rekluse.com/  | ||

From the Rekluse website: FAQ: Rekluse ProStart Clutch for Harley-Davidson Q. What is a ProStart Clutch? A. The ProStart Clutch is an automatic clutch designed to work with Harley-Davidson motorcycles. The ProStart Clutch allows the rider to control the bike by simply using the throttle and eliminates the need to use the clutch lever for starting and stopping. The ProStart provides smooth stops and starts every time and eliminates stalling. Q. Does the ProStart automatically shift the gears? A. No, the ProStart uses centrifugal force to automatically engage or disengage the clutch, allowing the rider to still shift gears. It is still necessary to ride in the appropriate gear. Q. Can I eliminate the clutch lever if I get a ProStart? A. You can eliminate the clutch lever completely. However, Rekluse strongly recommends that the rider retain the clutch lever in conjunction with the ProStart to allow for smoother shifting. The gearing in the Harley-Davidson may make it difficult for some riders to smoothly up shift without the clutch lever to completely disengage the clutch. Q. How does a ProStart work? A. Great! You should buy one. The ProStart Clutch uses a system of balls and ramps that use centrifugal force to engage the pressure plate in the clutch. At engine idle, the balls are down in the slots on the pressure plate. As RPM increases, the balls climb the ramps by centrifugal force and start to push against the ProStart top plate. At approximately 1100 RPM the balls force the pressure plate into the clutch basket and begin to engage the clutch. At approximately 2250 RPM, the ProStart Clutch is fully engaged and provides equivalent clamping pressure to the stock clutch. When RPM drops below 1050, the balls fall back down the ramps and an internal spring pushes the pressure plate out, disengaging the clutch. Q. Do I need to adjust the ProStart? A. No, the ProStart is designed to engage at approximately 1100 RPM on all Harley-Davidsons and disengage at approximately 1050 RPM so no adjustment is necessary. Q. How long will the ProStart last? A. The ProStart wears the friction plates in the same way that the stock clutch does. As long as the ProStart installed gap is maintained, the clutch pack will last as long as or longer than normal. The actual ProStart clutch assembly is made out of hard-anodized billet aluminum and heat-treated steel and should not have significant wear. Q. What kind of maintenance does the ProStart Clutch require? A. The ProStart operates based on the installed gap which is the distance the balls have to move to fully engage the ProStart pressure plate. The installed gap needs to be set at installation. It should then be checked after the first 1000 miles of ProStart operation and every 5000 miles thereafter. Q. How do I install a ProStart Clutch? A. The ProStart Clutch is designed to replace the stock pressure plate on the motorcycle. The main parts of the installation include mounting the ProStart to the center clutch and adjusting the clutch cable for proper operation. Q. Do I have to modify my bike to use a ProStart? A. The ProStart is designed to simply replace the stock pressure plate on the motorcycle. In order to make enough room for the ProStart on '98 and newer Big Twin models, it is necessary to machine down the center clutch using a special tool that is provided by Rekluse. Note: spacers are available so you can always put the stock pressure plate assembly back in the motorcycle. Other ProStart models (older Big Twins and Sportsters) require no modification to the bike. Q. How long does it take to install a ProStart Clutch? A. Installation time varies based on the accessories on the bike. Actual installation of the clutch itself will take between one and two hours. Q. Does installing the ProStart Clutch affect my Harley-Davidson warranty? A. The ProStart only wears the clutch pack of the motorcycle. Harley-Davidson does not warranty the clutch pack. Rekluse warranties all Rekluse parts for any defects for a period of one year from the date of original purchase. Q. What bike models are supported by the ProStart Clutch? A. Rekluse currently has ProStart models that support the following models: •'90-'97 Big Twin models •'98 and newer Big Twin models •'94-'03 Sportsters (Note '91-'93 Sportsters can be supported if an aftermarket side cover and derby cover are purchased) •'04-'07 Sportsters •Hydraulic Clutch models - call for more information Q. Does the ProStart support a Buell? A. The ProStart Clutch for '94-'03 Sportsters will support non XB models of '94-'02 Buells. Buell XB models are not supported. Q. Does the ProStart support the V-ROD? A. The ProStart does not support the V-ROD. At this time there is no plan to provide support for the V-ROD. Q. My Big Twin has a hydraulic clutch lever will the ProStart work? A. The ProStart will work fine with aftermarket hydraulic clutch kits such as the Magura kit. However, a special model of the ProStart is needed for '98 and newer Big Twins that have a Harley-Davidson hydraulic clutch (factory or dealer installed). Please call for more information on Harley-Davidson hydraulic models. Q. My bike has EFI, will the ProStart work? A. The ProStart is tuned at the factory to engage and disengage at approximately 1000 RPM. An EFI model idles roughly 50 to 100 RPM faster than a non-EFI bike. However, this is still in the engagement range for the ProStart clutch so it works fine with EFI models. Q. Does the ProStart work with open primaries like BDL or Primo? A. No, the ProStart only works with a wet Harley-Davidson primary. Q. My bike doesn’t have a Harley motor but it has a Harley primary, will the ProStart work? A. Yes, any motor is fine as long as it is using a Harley-Davidson primary. Q. How much horsepower will a ProStart handle? A. The ProStart performance is dependent on torque rather than horsepower. Torque is roughly equal to horsepower. The ProStart is available in two models. A ProStart model is available for '98-'07 Big Twins with stock or slightly higher torque (up to 90 ft-lbs of torque). For customers with modified engines or trike applications, the ProStart-HP model is available (up to 130 ft-lbs of torque). Q. How many ProStart clutches has Rekluse sold? A. Rekluse has already sold over 380 ProStart clutches. The ProStart Clutch is based on the same design used by Rekluse’s industry-leading z-Start Clutch for off-road motorcycles and ATVs. Since starting business in 2002, Rekluse has sold over 12,000 z-Start clutches to motorcycle enthusiasts all over the world. Harley-Davidson Sportster 883/1200 '04-'09 ProStart RMS687 $629.00 | ||

I'll pass. Having used a Recluse on a dirt bike, they have their good points and bad but I'm not a fan. It might be OK on the street but here are the deal killers for me offroad: 1) If you kill it or drop to idle on a hill, you'd better be on the brakes or you will be going back down the hill backwards at a high rate of speed. Remember: Throttle closed=effective neutral. 2) No engine braking going down steep hills. See point 1. 3) Increased clutch wear and heat. Because people tend to run them a gear or two high off road, there is a lot of clutch slippage and attendant wear and heat. My Uly runs plenty hot as is. 4) Expense. Some swear by them, some swear at them. I'm in the latter group. Again, they may be OK on the street, but the only way I would own one is if I had some issue with my hand that I couldn't hold a clutch lever in for long periods of time. YMMV. | ||

On the dirt bike models it's really all about the stall speed you set them up at, it sounds like yours is/was set at a higher stall speed. I have one in my dirt bike and ride with many other riders who also do, my stall speed is set up just off idle and I have engine braking going down hills just like a clutch set up, the only time the clutch disengages is if I lock up the rear wheel (which is what the Rekluse is was designed to do, eliminate stalling), then a simple blip of the throttle has it back engaged with compression braking. As far as heat is concerned your right....if you run it in a gear too high and slip the clutch all the time....but that's hardly the Rekluse's problem. | ||

I am looking to buy a Buell Ulysses and one of the first things I am going to do is put on a Slipper clutch to control all the torque power this motor puts out. Yes, you do have to set-up the clutch to the RPM's you want it to engage or disengage and get use to how it works. You still have a hand clutch like normal plus you have a slipper auto-clutch. I do not think slipper clutches run any hotter than a normal clutch working when you ride them right. It's not stalling the bike out on hard braking or slow speed stalling in tight slow riding. All you have to worry about is just work the gas in the right gear and shift accordngly up or down. Don't worry about the motor just pick your lines and enjoy the ride. One of the reasons I am getting a Ulysses instead of a BMW GS1200 Adventure is I can use a slipper clutch to control the motor. This thing is a monster torque power tractor that a slipper clutch can only help in riding it hard the way it was design for both on and off road. I am even going to put on the Magura hyrdulic clutch with the EZ pull clutch kit so I can one finger the clutch when I would want it to power clutch to raise the REV's quick to drop the power hammer. Once your use to a slipper clutch that's set up right it's hard to go back I think. My question is which slipper clutch to buy either the Rekluse or the STM? Anyone got ether one, what do you think of it? Let me know  | ||

Trans... The STM slipper clutch and this auto-clutch are two different things. I use an STM on my R6 race bike and it works wonderfully to control back-torque when down shifting, so as not to lock the back tire. This thing is designed to make your manual, clutch operated transmission operate like the trans of a manual shift, utility ATV (no clutch, just gear shift), not a true slipper clutch like the STM and others. The two are different things. My $.02 |
