Hi, up for auction is a   SET OF 4 ROTAX 912-S PISTONS   in very good condition. These parts came off a late model ( 2019 ) certified 100 HP Rotax 912-S engine with serial number 9139134 . As can be seen in the pictures, they come complete with piston pins and all the rings which move freely, nothings stuck. 

Please don't forget to take a look at my other auctions where I have a lot more rotax parts listed.
