Hi all, just counted the pennies in my piggy bank... have enough for a slipper for the 848... I think... Was going to go for new unit (oil stuff means giving it a service is not going to happen as much I do on the 748 JHP unit) Do I go for Sigma unit (£675), or Ducati performance part (probably more than that; can't find a price anywhere...), or something else? Do I keep it wet, or go for a dry conversion? All comments most welcome... money burning a hole in my pocket; so must buy soon... :wink: Many thanks, Bob
Must be an STM/Bucci version out there? Converting to a dry setup isn't going to save you any money at the end of the day
I love the Ducati rattle from a dry clutch so I'd go down that route. Plus you need to keep them in a fairly tight clutch pack thickness window (36-37mm normally) so it makes this a bit easier.
cheers for the replies so far... Wasn't going to convert to save money, just so it's easier to service... I strip the 748 slipper clutch every few track days and give it a clean... that's what I was recommended to do... If I have to ditch the oil every time then it won't happen as often... pretty close to getting a wet sigma unit; but just wanted a few opinions before I do... spoke to sigma and they said they get less hassle from a wet unit... stripping and cleaning a dry clutch ain't that hard so I don't mind doing it every few outings; but to be fair, sigma probably know a bit more about clutches than I do... I've seen a few alternatives on eThief (German), but if I'm going to bolt it up and fill it full of oil, I'd rather have peace of mind that its all good inside... Nothing against German engineering; but sigma have got a very good reputation; so keen to get one of those or genuine ducati... fair comment about adjusting pack height... but... I did about 10,000 road / track miles on a standard clutch on the 748 and didn't adjust it at all... I swapped it for a slipper from JHP and done about 1,500 track miles since with no adjustment... just strip, clean, and replace as it came out... Only time I've had to mess around with pack height was with my mates 748; which was running an MPV slipper...(yep, german I believe ! ) so before I posted I was going to get a wet sigma.... advantage of getting a dry conversion is that I'll have a spare on the 748 that I can put on if required... I'll let this roll for a while and take in the feedback... I do miss the a dry clutch though, along with a few other 748 / 916 / 996 / 998 stuff... the fact that I could pop the fairing, seat and tank off with only an allen key... they are a pleasure to work on... working on the 848 is not the same; and a big reason why I didn't get an 899... Single sided swinging arm? WTF? :smile: Cheers, Bob
I had nothing to compare to other than the std one in my gixer, which unless you blip a little will lock and squirm the rear esp if two or three gears at a time. In comparison, I could go from flat out, heavy brakes unloading the rear at Park corner Cadwell, down three gears (in one go) dump clutch and total control. if I were buying another, and i may well be soon as I can afford it, it will be sigma
Yep, sounds good to me... It was doing that very same bend on the 748 that I knew that getting the slipper was a good idea... combined with a ride out on the road in not so sunny wales; head up my hoop, come to bend; down 1 gear too many, OFM... :wink:
Wet and slippery is best...:wink: I have bradder's old sigma in my track bike now. Wet slipper is fab, I have an STM dry in the 1098 which feels properly agricultural in comparison.
Agree completely. I have a wet sigma in my 848 track bike and it is light years ahead of the dry one in my Desmo and needs zero maintenance. I can understand the engineering logic of a dry clutch, and the supposed maintenance (i.e. you can do it at the side of the track without needing to wait for new gasket to seal), but for anyone other than a full on race team, dry is a waste of time compared to a good wet Sigma one. Plus you change out the oil after every 2 days on track anyway, so that keeps the oil clean, regardless of the clutch wear getting in the oil. My sigma is ace. Fit and forget and you can hammer them. Just get one and don't worry.
I ran Sigmas on my CBR1000rr s without any problems whatsoever. That included approx 9,000 miles a year on road and track.
I have a Sigma on my 998 and it's the best of the lot from my view. I have a DP in my 748SPS and it's not nearly as good.
All, Many thanks for replies.... Advice seems to be to go with a sigma and keep it wet... That I shall do as soon as the UK wakes up... By the looks of it, the clutch holding tool I've got for the 748 won't work... like this one here DUCATI CLUTCH HUB TOOL 748 749 916 996 998 999 Monster | eBay Any comments before I splash out £40 on one for a wet clutch... Also, I just looked in the manual and i seems that there is no gasket, just re-seal with liquid gasket? any comment?? Thanks, Bob
Gasket sealant (needed) would be correct, the dry clutch Ducati's are the same, the casing is sealed with a sealant in the same way. I am not sure about the clutch holder as I have only ever had dry clutches on my bike, no doubt others will advise.
