Scorpa 175 Piston

Featured Replies

as title, have got a 175 (163cc) and would like to source a piston just in case, also would not mind going a little bigger on capacity, I know 150cc pistons are readily available for TTR yams so they would fit but apart from christian rayer who sells 200 kits (and wont reply to several emails ?) I cannot source a suitable piston, has anyone found an alternative ? i.e. a big bore tlr or something ??

The piston dimensions are pretty unique.. I've not been able to source anything even remotely close. Closed I've got is a piston from a chinese quad but even then the pin to piston crown height is 1mm short and that takes a 125 to c. 140cc. I've looked at most makes and models without success.

If you find something i've missed, please let me know and good luck!
