§ 02 / About this part
What it is
The PROX PISTON KIT FORGED 96.96MM B, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
This B-grade forged kit is intended for cylinders that have worn slightly beyond the initial factory A-spec. It replaces OEM part 33D-11631-00 and sits in the engine to convert combustion into drive. Forged components are preferred for their strength-to-weight ratio in large-bore four-strokes. Swapping the unit before the skirt fatigues is vital for engine longevity. This kit includes the rings, wrist pin, and circlips. Use a torque wrench on all head bolts and follow the specific break-in procedure to ensure the rings seat correctly against the cylinder wall.
