PROX Steel Intake Valve Conversion Kit - Honda

Designed by PROX, a recognized specialist in engine parts, this steel intake valve conversion kit is aimed at motocross and enduro riders looking for a robust replacement part for their cylinder head. The steel valves are intended for installation during an engine rebuild or preparation where reliability and longevity are desired in demanding riding conditions.

  • Material: steel valves
  • Usage: replacement of intake valves on compatible models (motocross)
  • Advantage: design suited for motocross demands, good wear resistance
  • Installation: requires clearance adjustment and inspection of guides/seats; installation recommended by a qualified workshop

This kit integrates well into maintenance and preparation operations: cleaning the cylinder head, resurfacing the seats if necessary, and checking the valve clearance will help optimize engine performance. PROX provides components designed to last in the field, without unverified technical promises.

  • Manufacturer reference: 28.SIS1336-2
  • Compatible motorcycles (examples): HONDA CRF 250 R / CRF 250 X (models listed above)
