Aftermarket replacement part for:
Raptor 660r Yfm660r 2001-2005
Raptor 660r Yfm660r Limited Edition 2002-2005

Designed to fit the Yamaha Raptor 660R, this OULI gasket overcomes inherent weaknesses in stock seals, such as high-temperature brittleness, flange deformation, minor oil leakage and ultra-fine desert sand ingress.

It creates an industrial-grade pressure seal between the crankcase and side cover, keeping engine lubricants fully contained while fending off floating sand, trail debris and ground moisture from sensitive internal engine hardware.

It shields stator coil windings and key engine internals from friction wear and rust formation, delivering reliable cold starts and consistent power performance ideal for dune racing and leisure off-road adventures.

Made in full accordance with OEM factory standards, it allows straightforward replacement during regular maintenance, lowers frequent repair costs, and greatly improves the long-lasting reliability of the ATV engine unit.
