Anyone familiar with this new clutch

[Ncdan]

I just saw an add for an apparent new type of clutch. Im sorry I don’t know how to enter it here. It’s called  REKULSE and you can google reklusecom  The add is a Video and it shows a guy on a harley coming to a stop lite and not using the clutch, with th the bike still in gear. When the light changes he just pulls off with gas only just like a cyntrifical clutch , changing gears with no clutch at all. The add also goes on to say you can use the clutch if you feel the need but not necessary. If this thing works it could be a good thing for some folks that have hand and strength issues, check it out and give your thoughts.

bought one for my harley. returned it. I thought it was a joke, a gimmick. If I adjusted it to fully disengage, it was jerky on the uptake. If I adjusted it to be smooth, it didn't fully disengage. Its a centrifugal clutch that they try and make small enough to fit in the same space as the stocker. It uses small ball bearings and the centrifugal force driving them outward in ramps to engage/disengage the clutch.

Nothing new under the sun.  I once owned a Harley Davidson Scoot-Away TOPPER.  Wish I still owned it!  Centrifugal clutch and variable pulleys and belt drive.  Used three giant ball bearings to drive the centrifugal ramp system to change the effective diameter of the front belt pulley.  Drive system was designed by SACHS I believe.

I saw one of these new fangled clutches in demo on a BMW show last year.  Seemed interesting, but might effect a lot of low speed or low rpm driveability functions.  Certainly effective for someone with ability limitations.

These are popular on dirt bikes and dual sports, as it makes it easier to pick through rough single track at slow speeds w/o being on/off the clutch so much.

How does this work on a Harley? Most riders keep rapping on their throttles at an intersection for noise. Man, they would shoot right through the intersection if they forgot they installed it.....

That variable belt drive was used
on some scooters and may well be still. Our French teacher at college had a wierd Manurhin ?? Scooter that used it.

Centrifugal clutch with slipper arrangement been around a number of years some of the enduro riders were using them (on a 300 TM stroker no less) did put a fair bit of heat back into the engine cases apparently, I very much doubt it could be applied to a Guzzi as it is based around the standard motorcycle multi-plate basket design.

Patrick.. you are the first guy I've ever heard of that actually owned a Topper.

Most current scooters have centrifugal clutches for twist & go throttle operation, including my 3 Italian maxi-scooters (250, 400, 460).  Mine disengage when I get down to maybe 3 mph before stopping.  Mine have phenolic? rollers that engage the front pulley/belt drive.  Periodically I have to replace the rollers.  The front pulley expands/contracts to change the drive ratio of the belt for X speeds.  It's really a simple design that works.
