The piston travels within the valve rod housing bore and is the direct mechanical link between the pneumatic bellow and the exhaust valve itself. Tightening torque is 1–2 Nm — this is a precision-fit component and must be handled carefully. A worn or scored piston causes binding, inconsistent valve travel, and erratic power valve RPM response.\u003c\/p\u003e\n\u003cp\u003eFits the Rotax 125 \u003cstrong\u003eSenior MAX EVO and Junior MAX EVO\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e R.854440\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTightening Torque:\u003c\/strong\u003e 1–2 Nm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Rotax 125 Senior MAX EVO, Junior MAX EVO\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCMC Karting stocks the exhaust valve piston alongside the valve rod housing and full E-RAVE assembly parts for complete power valve overhauls.\u003c\/p\u003e","brand":"KSG\/Karting Solutions Group","offers":[{"title":"Default Title","offer_id":48139141021917,"sku":"R.854440","price":29.09,"currency_code":"USD","in_stock":true}],"url":"https:\/\/cmckarting.com\/products\/rotax-max-erave-exhaust-valve-piston","provider":"CMC Karting","version":"1.0","type":"link"}
