Cometic .030" MLS head gasket for 2016‑on Triumph T100 Bonneville applications (85mm bore) uses multilayer steel construction with embossed outer layers and an uncoated stainless shim. That design helps distribute clamping loads, reduces bore distortion and meets demanding sealing conditions. The MLS build is presented as a direct replacement matching the stated bore and thickness.
