Constructed from high-quality, heat-resistant sealing materials, this gasket provides a reliable barrier against coolant and oil leaks. The 0.75mm thickness is specifically chosen to help tuners and mechanics achieve the correct squish gap for the engine. Using genuine parts helps maintain the longevity and factory-spec reliability of your motorcycle's top end.

When installing a new cylinder base gasket, ensure both mating surfaces are completely clean and free of old gasket residue or debris. It is highly recommended to follow the manufacturer's specific torque sequence and specifications for the cylinder base nuts to ensure even pressure across the seal. Always inspect your piston and rings while the cylinder is removed for maintenance.
