§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 55.95MM B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This top-end part is critical for high-revving small-bore engines. It converts combustion energy into the stroke that drives your bike. The B-sizing accounts for the natural wear of the cylinder plating over time. Replace this at the recommended service interval to avoid skirt collapse or ring failure. Measure your bore with a dial bore gauge to confirm this 55.95mm diameter is appropriate. Use a torque wrench on the cylinder head bolts to prevent warping. Ensure the circlip gaps do not align with the removal notches in the piston.
