The Rotax MAX EVO uses a single rectangular compression ring seated in the piston ring groove. This ring forms the primary gas seal between the piston and cylinder wall — maintaining the compression and combustion pressure that drives piston movement. A worn or broken piston ring causes loss of compression, blow-by into the crankcase, increased oil consumption from the gear side, and a characteristic white smoke from burned gear oil. Replace at every piston change or any time compression testing reveals a piston ring sealing issue.\u003c\/p\u003e\n\u003cp\u003eCompatible with all Rotax 125 MAX EVO variants: \u003cstrong\u003eRotax 125 Senior MAX EVO, Junior MAX EVO, Mini MAX EVO, Micro MAX EVO\u003c\/strong\u003e. The piston ring is pre-installed in the Piston Assembly (R.295509–R.295515) but is also available separately for use with an existing serviceable piston.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e R.215548\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Rectangular compression ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification:\u003c\/strong\u003e IS2 – 54\/49.4 x 1mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Rotax 125 Senior MAX EVO, Junior MAX EVO, Mini MAX EVO, Micro MAX EVO\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCMC Karting stocks the piston ring alongside piston assemblies, wrist pins, circlips, and the full Rotax 125 MAX EVO top-end rebuild parts.\u003c\/p\u003e","brand":"KSG\/Karting Solutions Group","offers":[{"title":"Default Title","offer_id":48168085946589,"sku":"R.215548","price":81.49,"currency_code":"USD","in_stock":true}],"url":"https:\/\/cmckarting.com\/products\/rotax-max-piston-ring-rectangular","provider":"CMC Karting","version":"1.0","type":"link"}
