§ 02 / About this part
What it is
The PROX PISTON KIT ALUMINUM 53.96MM B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
The B-grade sibling at 53.96mm, sized for a YZ 125 or YZ 125 X bore that gauges just over standard. Same OEM cross-reference, 1C3-11631-01-A0, one hundredth up on the A. Grade selection matters on a small-bore two-stroke: too tight seizes, too loose rattles and wears the skirt. Measure the cylinder before ordering. Rings, gudgeon pin and circlips come in the kit. Oil the small-end bearing on assembly and run it in before holding it wide open.
