16775-52 Gaskets, O-rings & Seals for K, KH, XR & Ironhead Sportster 1952-1971

Restoring or maintaining a classic K-model or early Sportster requires parts that respect the original engineering while offering modern material benefits. This Athena gasket fits 1952 to 1956 K and KH models, as well as 1957 to 1971 Ironhead Sportsters and XR models. It is a direct replacement for OEM 16775-52, providing the critical seal needed for these early mid-century engines. Athena manufactures these to exacting standards to ensure they can manage the unique requirements of the 45-cubic-inch flatheads and the first generation of overhead-valve Sportsters. For any mechanic working on these historic machines, this gasket is a reliable choice to prevent leaks and maintain the compression necessary for smooth operation.
