The Cometic MLS head gasket for Yamaha RX1 (75mm bore) uses multiple embossed layers combining AMP (Advanced Multi-Polymer) coating on outer layers with an uncoated stainless steel shim at the core. This construction meets demanding sealing environments and load conditions, allows varied center shim thicknesses, requires less clamp load to reduce bore distortion and helps distribute clamp load evenly across the sealing area.
