Dear Ducati Community, I need your help. Currently I’m working on my final paper in Germany at the university Ravensburg. I’m particularly interested in your opinion about slipper clutches or 'back torque-limiting' clutches to form an opinion for this motorcycles- accessory. I place this survey in several forums and hope you bikers can support me. I thank all those who take 5 minutes time to answer my 5-7 Questions. http://https://docs.google.com/spreadsheet/viewform?formkey=dG44YjYzd08zb2NQOXdhX0t1Z1UzNVE6MA In addition, I would like to discuss your views and opinions in this thread. Thanks for the support, would be great if I get a lot of opinions for my final paper. With best regards Florian
However. Sigma dry slipper on 853R/RS - works well, set to slip at 7500rpm. Aids stability on track. Just fitting an APTC unit on my other race bike (620ie engined 600ss) so do not have any idea of its functionality, I suspect it will not function as well as the sigma dry slipper. I raced for one meeting withouth the slipper in the 853R/RS and found I was working harder on downshifts and the back end was a bit more wayward during hard braking. Very useful for track based riding, cant see the point of one on a road bike, but I do not ride on the road at all.
yup, doesn't work for me either. However, I wouldn't necessarily agree with the view that they're better on the track. I had a major moment at Mallory on my Monster without a slipper and fitted one asap. Normally, I'd say that downshifts on the track are more likely to be planned, whereas you might want to go down the box more quickly on the road in response to an issue. That said, if you're braking that hard, it's unlikely that the rear is going to be on the road anyway...
I can see that on a track a slipper clutch would have it's benefits but I can't see the point of them on a road bike.
mainly in low traction conditions I'd guess. I ride all year round and have had a wayward rear on occasion.
Why would you bang it down through the box in low traction conditions on the road ? If there is potential use for on the road I would like to understand it, but I am struggling. The OP was probably more interesting in track riding ??
yes, maybe. I'm thinking of back lanes, maybe with a gravel patch or an unexpected pile of wet leaves. Throw in a car or a van coming in the opposite direction and you might well want to stop quickly without the back end hopping about like the energiser bunny. It's distracting. But, yes, positioning, observation and speed.
Never tried one, never felt the need, never locked the rear due to harsh downshifting, but I'm oldschool and not a racer.
Had one on my 999s and hated it. However this is prob more to do with my "ambition out weighing my talent" (Thank you Mr Stoner for that quote)
I can't open the form either but Ive had them on my GSXR1000K6 and R1 Crossplane crank. They are brilliant even on the road. Especially the way I ride :tongue:
Can't open form either. But then as I've never had a slipper clutch or ever missed having one, my opinion is probably not going to be very enlightening in any case.
Me no openy formy eithery. I tihnk for me the way I ride in my competitions it is invaluable as I just bang down the box and let it happen , without it the rear wheel would be locked up immediatley I would say you'd have to ride like a loon on the roads to need it. And if you need it you are close to being out of control. just my tupence.
I have a DP dry slipper clutch on my 848 and it makes the ride sooooooo much nicer on road and track. So much so that I doubt I'd own another twin without a slipper clutch.
if you ride like derick dayglow you will never need one but on hard breaking into corners you will never lock up the rear end again as i did many times before fitting one however they do ware out quicker and make more noise than a standard one and under 3000 rpm they are horrid
I've had an occassion on the road that a slipper clutch may have helped. Was riding a 916 on a very tight twisty road in 1st and 2nd gear. Got in a decreaseing radius corner and ran out of talent, let off on the gas to much and the rear broke louse. Was able to save it but was blind luck. Thought at the time a slipper clutch may have been an asset.
