PISTON RINGS, ISETTA 250 & 300

These aftermarket multi-piece piston rings offer improved sealing over stock. The lower oil control ring is a three-part ring: two thin chrome-plated steel rails and an expander between them. These conform to irregularities in the cylinder walls better than the stock ones. The middle ring is a two-part ring: one, a nodular cast iron ring slightly larger in diameter than the second, which is a chrome-plated steel ring. The end gap of one piece is 180 degrees from the other, resulting in an endless ring. The soft cast iron ring gives quick seating; the chrome-plated steel ring provides long life. The top ring is a conventional chrome-plated one.

Available for Isetta 250 & 300 in standard size and all oversizes. State bore size when ordering.
