§ 02 / About this part
What it is
The PROX PISTON KIT ALUMINUM 56.00MM STANDARD, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
Restore lost compression and engine response with this top-end refresh. This component sits inside the cylinder bore, converting combustion into mechanical drive. Regular replacement is essential to prevent skirt fatigue or catastrophic failure in high-hour engines. This standard sizing is intended for stock bores within factory tolerances. It serves as a direct alternative to OEM part 3MB-11631-00. During your rebuild, verify the ring end-gap and ensure the piston arrow points toward the exhaust port. Always use new circlips and lubricate the small-end bearing thoroughly before fitting the cylinder. Check your service manual for specific ring orientation.
