Description

The Athena P400485850400 is a complete engine gasket kit designed for a full engine overhaul. Athena has over 40 years of experience and engineers its kits in Italy using advanced laser technology for precise cutting. The gaskets offer low moisture absorption, high mechanical resistance, and resistance to oils, gasoline, high temperatures, and pressures.

This kit includes all necessary gaskets for a complete engine rebuild, excluding oil seals. It is compatible with the Yamaha XS 400 cc from 1977 to 1982. Athena's gaskets are known for their easy removal and ability to compensate for irregularities and improve sealing in critical areas.
