I've just ordered a slipper clutch for my 1098s. Looked at loads, but finally decided on a Bursi Evolution. Bursi are an Italian tuning company the specialise parts for Ducati, when their name pops up, it always seems to be good. This slipper comes in at circa £315 at todays exchange rate. Postage is included in the price: Frizione antisaltellamento per Ducati Monster / 998 / 999 / 1098 Hope this helps.
Whilst the quality of the Bursi product is not in doubt, I buy from them and have bought that clutch but you have to understand that the centre and basket are made from Ergal and if you use steel plates these parts will wear quicker. Aluninium plates are readily available but I have never seen aluminium plates with sintered friction material only organic. I have ridden a road spec 748R with organic friction plates and a track hybrid 748R with a 748RS engine running sintered friction plates and I prefer sintered. Andy
I bou I bought a Sigma slipper a few years ago and I'm sure that was an alloy too, but at twice the price. I'm pretty happy that Bursi use Ergal (7075) as this is a product designed specifically for engineering applications - see below: Material Notes: General 7075 characteristics and uses (from Alcoa): Very high strength material used for highly stressed structural parts. The T7351 temper offers improved stress-corrosion cracking resistance. Applications: Aircraft fittings, gears and shafts, fuse parts, meter shafts and gears, missile parts, regulating valve parts, worm gears, keys, aircraft, aerospace and defense applications; bike frames, all terrain vehicle (ATV) sprockets. With regards to the clutch plates, I've never used alloy versions, but Bursi are clear to say that the original clutch basket can be used instead of the one supplied, so keeping this and using the original steel plates wouldn't really cause too much of an issue.
