The piston rings are very brittle. I had to order a second set of rings to replace the first set. I could not open them up enough to clear the dome of the piston with out breaking them. *Mopeddivision "Installing rings is tricky business, great care must be used when doing so. It helps to watch a couple videos if not completely familair."
Airsal A55 38MM Piston Kit
Nice fit and finish, very similar to OEM. Recommend this over the "generic" offering. Worth the few extra bucks.
Airsal Puch Piston
Seems of decent quality and dimension. Be aware that it is machined towards the small end of the Puch world (a hair smaller than a #1 or 11) likely so it will run in any bore. My bore was tight, so this is great. Oh, 1.5mm rings instead of 2mm.
Its an italkit oiston, what more is there to say. Super high quality
Just what is states, perfect if you want to refresh your stock kit. Most kits appear to have this style piston with the 12mm wrist pin so most chances this is the one you will need, but always double check. And recommend running a hone through your cylinder prior to installation. Works great and has lots of corpression, for under $30 bucks I refreshed my stocker swinger, cant beat that.
