Heh, you wish!

Besides, it appears we were both right ;)

If smilo006 builds his plate stack height right, ie 4-5mm depth down from the edge of the centre hub, i dont think a toothed cover will physically work with it.

Plus if you think what a slipper does, then you really want all rotating parts operating independantly so they slip when the reverse torque is applied.
With the pressure plate toothed to the centre hub this would be two less bits able to slip independantly.

We all know the noises and feeling a slipper makes when its not happy.......

Steve, arnt you running a 748r std slipper? i guess thats why you use a toothed std pressure plate!

yup i am.

It is toothed and the teeth fit the basket well. Seems that the centre nut holding the clutch in is different on a slipper than on the regular cluch.

Anyone want to buy a little used speedymoto clutch pressure plate or swap for one that fits an STM slipper cluch!!!!!

Thanks for the advice.

my Bucci PP has no teeth - but it does have a friction coating on it!

The pressure plate and the clutch centre need to match, in that the posts need to be the correct length to match the depth of the holes for the springs in the pressure plate. I've recently fitted a Sigma clutch to my bike and it was very noticable how much lower the spring post ends are on the new clutch compared to the old "standard" Ducati slipper clutch that came with the bike (748R). The Ducati pressure plate will certainly NOT work with the Sigma centre, if you were to fit the Ducati pressure plate on the Sigma centre then the springs would be coil-bound before you finished tightening them. Might the same thing apply here with an STM centre and a Speedy-Moto plate?

I know there are two different sized spacers - one for a slipper clutch and one for the standard clutch, the slipper being shorter. How does this affect things?

I'm having a real hassle trying to get hold of the shorter one at the moment for my spare slipper clutch I'm trying to sell!

doesnt that ebayer who sells alot of ex wsbish slippers quote the ducati spacer part number available from all dealers?

Probably - it's getting one that's the problem!

what do you mean by spacer?
The bloke who sells these STM clutches mentions them on some sales, usually the 4 post ramp types but not the 6 post ball and ramp types.
