Designed for enduro riders and motocross pilots who are rebuilding a bottom end, this PROX piston fits into a reconditioning project to restore original tolerances. Made from aluminum, it features a domed head suitable for the combustion chambers of 250 SE-R single-cylinder engines, and a standard compression to maintain factory settings.

  • Piston diameter: Ø 66.350 mm (oversize B - indicated Ø 66.36 mm)
  • Compression: standard
  • Material: aluminum
  • Specificity: domed head
  • Usage: reconditioning equivalent to original equipment

This piston is intended for modifications and repairs on motocross engines where bore precision and geometric compatibility are essential. When replacing, check rings, pins, and cylinder/piston clearance, and follow manufacturer recommendations for break-in and installation to ensure a consistent lifespan of the moving assembly.
