■Features

• Stopper type gasket with a high compression ratio design is now available for NA setups.

• The thickness is set at 0.7mm to increase compression ratio, thinner than the grommet type (t=0.8/1.2) already on the market.

• Thickness is calculated in consideration of surface grinding during overhaul and pivot of the large-diameter bore piston.

• High sealing performance is ensured by using a separate stopper structure for the bore seal section.

• Head and cylinder surfaces are coated with a special coating to improve sealing between the head and cylinder.
