The Cometic .018" MLS head gasket for Yamaha YZF-R6 (2003–2005) and YZF-R6S (2006–2009) features a 68mm bore and multi-layer steel construction for dependable sealing. Embossed outer layers use AMP coating while the uncoated stainless center shim can be varied for thickness. The MLS design reduces clamp load, lowers bore distortion and helps distribute sealing pressure evenly across the combustion surface.
