§ 02 / About this part
What it is
ProX piston kit to fit the Sherco SEF 250, model years 2014–2015, and Sherco SEF-R 300, model years 2014–2017.
Your top-end rebuild relies on precise tolerances within the cylinder bore. This assembly replaces the reciprocating components to restore compression and throttle response. Most riders swap these at set hour intervals to prevent skirt failure or ring groove wear. Check your cylinder for wear and select the correct size grade for your bore. The kit includes the piston, rings, gudgeon pin, and circlips. Ensure the arrow on the crown points toward the exhaust port during installation. Always verify your ring end gap before final assembly to ensure reliable performance on the track or trail.
