hi, im new here so....... does anyone own a ossa 350 gripper, or know where i can find piston rings for one?

The 350 Gripper piston is the same as the 350 MAR but you need to know whether you have a genuine Ossa piston, which is a Tarabusi, or a pattern type. As it is a 350, chances are it is genuine Ossa as not personally aware of any patterns available for 350.

If it is Tarabusi it should have the name cast on the inside of the skirt and the rings are very very thin, very bendy and almost unbreakable. For Tarabusi try Jeff Bungay at Mainly Spanish - advertises in TMX or possibly Sammy Miller. Failing that you may get some from the US as can't think of anywhere else in the UK that will stock them now.

If pattern type piston then I don't know unless it is a GPM (I think that is the name) or a Dinamin as Miller used to sell these makes for the 250 MAR but not sure about the 350.

One last possibility is ex Ossa riders and dealers Mick and Bill Wilkinson in Kettlewell, North Yorkshire. They own a garage called 'The Garage' and may still have some Ossa stuff left. Don't know their phone number but Directory Enquiries should be able to get it for you.

- I'm assuming you're in the UK.

This Ossa website has a list of specialists near the bottom of the home page. Lots of other useful info too.
