January 14, 2026 · 1 h 7 min

Show notes

Early attempts at sealing pistons in cylinders included hemp and other natural fibers. Today's piston rings are made of amazing metallic materials that allow motorcycle engines to last longer than ever. Kevin and Mark dive into piston rings from the early days to now and talk about cylinder finish, ring gap, "flutter," and so much more. Join them on the Cycle World podcast!
