Hi all Thought I'd post a few pics of a rear shock absorber that came with my 900ss ie track project. Nicely made, I suspect low volume production it is an air shock made by "Double System" of Rome - It apparently has rebound and compression adjusters. Guy who sold me the bike says "it worked fine" although I do wonder whether the fact it was no longer fitted to the bike should tell me anything....... Searching the web throws up no information so I thought I'd ask if anybody on here has come across such a thing and/or has any set up info - Before I call the telephone number on the shock and hope they can speak English a little!!!! Any info gratefully received.
