Yes,a line lock whether manual or electric would do the trick as there is no engine braking or connection in gear as with a conventional pressure plate. When under approx 1500 rpm the clutch(as the name implies)automatically disengages. This thing has been around for a long time now and is not the latest whiz bang gizmo to come along.
  The engine can be started in gear and take off in any gear.At least theoretically. The biggest benefit I can see is taking off from a dead stop especially up hill.

From my reading yes it would roll away. Most seem to engage about 1500rpm (adjustable) and anything under that is like clutch in. Reading that some bike they completely do away with all parts of clutch, cables, lever handle, even have plugs to remove the arm from cover.
So for $700 u furnish basket or $1200 outright. Fabr u call h abiut them holding in a rail?
No,we are in the middle of inventory. Probably be next week before I can . They have been making these for a long time now. I'm going to ask if they would consider making from steel if they feel the alum would not be up to the task( I really don't see any issue tho). The steel would add a nice bit of rotating mass/torque for those "lug it out of a hole " times. Wouldn't be a lot but would help low end but hurt rpm quickness a bit.

Just got an email reply from efm. Yep,send in clutch basket,they modify for $695 + shipping. Gotta find time to call him now for a couple of questions. This will quite likely be on the busa buggy soon. My first concern was about low,low speed crawling in tight,tight terrain. Then I thought that the only thing needed to keep the clutch engaged fully was around 2000 rpm.  Sooooo, with the availability of 4 final drive ratios That can easily be overcome even if it was an issue. The clamping force and possible slippage at low rpms are still a concern to me but it shouldn't be.

At what RPM does the clamping force = what the regular clutch produces?

Good question. That is one of the questions I will have for him when I call. From what I see that would depend on the strength of the bellville washers and the number/size of the balls that provide the clamping force. I believe that it would be low,probably in the busa rpm range of 2000.m I'm rarely under 3K when duning. With my selection of final drive ratios I can easily pick a gear that will guarantee that.

 How about tempered (as in been through many fires and came though tougher than before) like a fine steel  ;D

Did you pull the trigger on this?  Has anyone else tried one of these in a buggy?

Thanks

I have one in my buggy, and I love it. You can still use the clutch if you need t some RPM's for a take off or launch.

I installed 2 years ago and havent looked backed. Also the higher RPM the harder it presses in the clutch pack. You want to keep RPM's over 1500 when driving slow just to keep it engaged.

Yes, your buggy will roll away on a hill if its in gear and not running.

I removed about half of the balls in the unit to raise the engagement. Im currently running GSXR 750 in a little 650# 2 seater.

AND, the verification questions to reply to a post are fricken ridiculous!!!

Welcome to the site. Sorry for the verificatin issue . We have had a LOT of issues with foreign spammers attacking the site. Hope you can understand. VERY glad you put forth the effort .

 Extremely happy you posted your experience with the auto clutch. Out of curiousity,would you mind giving us some info on your buggy? Size/weight/usage? Quite interested in using one on my busa,next upgrade possibly. I have heard reports of the balls "sticking "in their tracks. Any issue with that for you?
