Aftermarket replacement part for:
Gn250 1982-1988
Gz250 1999-2010

Engineered to replace stock Suzuki gaskets, this OULI unit eliminates common issues like high-temp fragility, cover misshaping, oil leakage and exterior dirt intrusion.

It crafts a flexible, leak-proof seal along the crankcase and stator/generator cover junction, shielding internal electrical components from oil residue, fine dust and humid exposure.

It keeps the bike’s charging system running consistently and protects the engine from avoidable damage, delivering solid reliability for daily travel and extended road trips.

Crafted to precise OEM factory specifications, it allows easy self-installation during scheduled upkeep, minimizing idle time and repair spending while greatly prolonging the motorcycle engine assembly’s service life.
