The thinnest available base gasket, approved for racing use only. Requires Silicone Compound Grease 897061 on both faces to ensure proper sealing — do not use dry. Base gasket thickness selection is one of the primary methods used to tune squish clearance on the Rotax 125 MAX EVO — changing the base gasket directly affects the distance between the piston crown and cylinder head at TDC, which influences combustion efficiency and power characteristics. All four standard thicknesses are included in the Engine Gasket Set (R.296160) and Cylinder Gasket Set (R.296161).\u003c\/p\u003e\n\u003cp\u003eCompatible with all Rotax 125 MAX EVO cylinders: \u003cstrong\u003eRotax 125 Senior MAX EVO, Junior MAX EVO, Mini MAX EVO, Micro MAX EVO\u003c\/strong\u003e.
