§ 02 / About this part
What it is
The PROX PISTON KIT FORGED 66.34MM B, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
This assembly restores lost compression and engine response. It sits at the heart of your engine bore. Regular replacement prevents catastrophic failure and maintains peak power delivery. The specific sizing allows you to match the part precisely to your cylinder wear. Always measure your bore before selecting a size. Ensure the arrow on the crown points toward the exhaust port during assembly. Check your ring end-gap against factory specifications. This kit includes the rings, wrist pin, and circlips required for a complete refresh. It serves as a direct alternative to expensive factory parts.
