The Cometic MLS head gasket for 2006–2017 Yamaha YZF-R6 (70mm bore, .018" thickness) is a multi-layer steel sealing product assembled from embossed AMP-coated outer layers and an uncoated stainless shim. It provides a durable seal suited to demanding motorcycle engines. The embossed outer layers meet harsh sealing and load conditions; the center shim can be varied to achieve required thickness, reducing clamp load, minimizing bore distortion and distributing sealing load evenly.
