I'm looking to replace the piston rings on my 92, 900SS. Are 1998+ 900SS rings compatible with 91-97 bike pistons or do I need to specify 91-97 rings (earlier ones are hard to get hold of I think)?
Got my last 2 new sets on German E-Bay I haven't used these but they certainly look ok if expensive :- DUCATI Kolben Kolbenringe 900SS Monster 900 Cagiva Elephant | eBay have you tried a Ducati dealer yet?
Don't remember the exact price but a set of piston rings for a 916 (like 900SS, only 94mm bore) cost me around £150 from a Ducati dealer - that's for one piston only. A set of high-comp JE pistons complete with rings for 900SS costs about the same (or less) than just the rings from Ducati...
