Honda cb750 Gaskets


Cycle X High Performance Gaskets

Honda CB750 Super Gasket Set  (Race Proven)
Cycle X Race Team Approved

Cycle X super gasket sets are a premium quality cure for age old problems concerning chrome covers, untrue surfaces, re-torquing and the need to run to the hardware store for miscellaneous "O" rings.
Cycle X was the first to put effort, expense and test these modern gaskets on Honda cb750s.

Head Gaskets: MLS head gaskets have been around for years.  They feature great rebound and are layered steel with a Viton coating.
Base Gaskets:  Steel with Viton coating.
Side Cover Gaskets: Alloy with Foamet coating is the same combination used to stop old Harleys from leaking.
Oil seals and every "O" ring in the motor that most kits do not include.

What is MLS?

The outer layers are an embossed viton coated stainless steel providing a superior seal with excellent rebound characteristics and are corrosive resistant.
MLS head gaskets reduce bore distortion and withstand extreme cylinder pressures.
