Slipper Clutches for S4Rs

02-07-2014, 03:25 AM

Im planning on fitting a slipper clutch when funds become available.

A bit of reading about has picked up a few brands, Sigma, Bucci, Ducabike(?).

Who here uses them and which do you use, prefer, pros and cons. Is it worth the little extra to get a race set?

cheers

For road use why bother?

If only for the bling factor isn't that enough reason?

There is some safety benefit I guess in preventing unexpected lock ups but you are right... unlikely to happen on the road.

If you're going to stick one on any monster, the RS seems like a good choice

No personal experience so can't help anymore...

Not sure about the race set but they're worth fitting on the bigger cc'd bikes if you already have to replace basket & drums

I rate the slipper clutch as one of the best mods I have made, suiting my riding style.
Most of what is out there are Bucchi clones including the DP item, which uses a six ramp and ball design.
They do wear at the point of the ball/ramp interface, careful assembly using molycoat will reduce this wear and also aid the operation.
The plate stack is different than standard, my differs from the Bucchi instructions and uses two dished plates. It has performed flawlessly.
I strip inspect and rebuild on an annual basis.

i have a 48 tooth STM Evoluzione slipper, it works very well
only downside over some other designs that it needs specialist tools to fit and remove to change the plates yourself

Exactly! If you go down that route we may as well sell our bikes and get bus passes!

i reckon if you had one on your s2r1000 stafford, you wouldn't go back

Slippers are good, even for road use, its a much better quality clutch that the standard item. It improves gear changes and just generally feels much nicer to ride. And you've got the saftey factor too!

I have a DP(Bucci) one in my S4 and I think its an STM one in my 748

I have an APTC slipper, whatever that is, on the 796 yet I still bounce the wheel about on downshifts on the road

Fun times!

None of this helps you I just thought I would let you all know.

I have one on my track bike and don't see the need for it on the road.

I'm not in any way endorsing Sigma, but there is a lot general info on the website:-

Had many over the years but currently have these two in use, both STM 48 tooth

Darren69 · 02-07-2014, 12:15 PM

That certainly looks different, novel venting solution. I think I'll be updating to a 48 tooth basket when it comes time to replace mine.

I run a Ducati slipper on my M1100s, and wouldn't be without one now.
Make's a differents on those twisty roads when your up and down the box.
Well recommended as an upgrade.
