§ 02 / About this part
What it is
The VERTEX PISTON KIT Ø 66.40 A, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This A-size kit is the standard replacement for your 2-stroke engine. It cross-references with OEM part 1P8-11631-00-A0 and is designed for cylinders with original factory dimensions. On a 2-stroke, this is a high-wear item that requires regular swaps to maintain primary compression and prevent skirt failure. This kit includes the rings, pin, and circlips. Check the ring end gap in the cylinder before assembly. Ensure the unit is installed with the arrow pointing toward the exhaust port. Use a new small-end bearing during the rebuild for complete reliability.
