The clutchpack number is 190 200 22A this is probably the number of the 91 ss 750 to match our bikes(given me by baines racing) however when I viewed a box 91-97 the steel plates are not different but all looked the same is this ok? because there is supposedly dished plates(or according to proper manual special disk (same thing) as posting by steve(search)......the clutch listing by gerhard shows mine was a modern clutch dry but there is no listing for paso's the forgotten motorcyle of ducatis cagiva takeover why...why...why.....my aim is to get my bike on the track again at olivers mount I did the dave jeffries tribute laps with john mcguiness what a memorable day that was if anyone out there has a photo of me Id be much abliged catch you later desmodave.

190 200 22A (old number 190 200 21A) is for 750 Sport ´88 - 90 / 750 SS ´91 / 900 SS ´89 -´90.
Sorry no clue where the exact differences are in this or the clutch pack you`ve got.
One could maybe check the complete clutch pack thickness and compare the 2 sets.

G.

found the info on site of a german Duc part supplier that 21A was replaced by 22A.
That doesn`t have to mean anything. Maybe Ducati changed supplier or who knows. Don`t think that there are any technical differences. Is it so hard to find the correct clutch set ? Almost can`t believe it.

Btw. the 91 SS was a further development of the 750 Sport.
Supersports after 91 had the clutch slave cylinder on the left engine side, not in the clutch cover like the Paso.
Only later "old" Supersports had the slave clutch piston in the clutch cover again, but these should be the models with wet clutch.
