I'm thinking about fitting a slipper clutch when funds allow, it seems like there is a fair bit of choice, anyone got any recomendations on best value/quality for road/odd track day use??

TIA

Oh the choices....

I guess you have at least the following

Bucci road/track
STM 48T
Ducati Corse
JHP/Sigma.... etc etc

Pros/Cons from my point of view

Bucci (Pros) - You can use your existing plates. plenty of spares and easy to maintain. (Cons) - Bearings supposedly need regreasing every 1000 miles (dunno if that is strictly fact or not), due to being a 12 tooth basket that'll wear quicker than the STM.

STM (pros) - Plates should last longer as there are 48 points of contact (Cons) clutch plates are more expensive as specific to the clutch, and you need a specific (expensive) tool to remove the pressure plate, if you were to do a foreign trip, or track day abroad and your clutch went could you find a set of plates?

Ducati Corse (pros) - probably the best action of the lot, I would imagine will take more HP than the others being a full race item (cons) - spares?

JHP/Sigma (pros) - cheaper? but pretty much identical to the standard 12 Tooth baskets etc (cons) - same as above.

have an stm 48t evolutione love it, had no problems with it probably done 4k+ with it so far. recommend.

I'd looked closest at the DPP road item as I wasn't too sure about plates, spares etc and also how long the race clutch would last.

I was pretty much decided that the STM 48T looked a good option. But I appreciate the spares are a possible issue!

As a matter of interest ... as the standard clutch basket seems to have small tabs and large area of basket between them, would the std plates fit the 48T basket in an emergency? Or is that really daft? (I have not seen an STM clutch (in the flesh) so I have no comparison.

12 tooth plates won't fit a 48 tooth basket I'm afraid.

I have the Corse slipper, as do a few others on here. It's a 12 tooth jobbie and very well made, but I *think* that it may be made by Bucci? Mine is a classic 6 ramp and ball bearing design but apparently Corse dropped the ball bearings and two ramps after that so they could put the plugs in to bump start the bikes without the clutch slipping.

I'd only get the 6 ramp and ball bearing version myself because I don't want to be pulling the clutch apart to grease the ramps regularly (lazy sod!).

Out of interest...anyone know how much a set of plates cost for a 48tooth STM slipper?

Don't forget the tool also for the STM
