§ 02 / About this part
What it is
The VERTEX PISTON TOP END KIT WR/YZ125, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
Small-bore two-strokes live high in the rev range, making regular piston swaps a necessity for race-ready performance. This kit replaces the worn internal components to maintain peak horsepower and prevent ring flutter. It includes the piston, rings, gudgeon pin, and circlips. For this bike, keeping a fresh top end is the best way to avoid expensive cylinder head or crank damage. Measure your bore to choose between the available sizes. Clean the power valve assembly while the cylinder is off to ensure smooth operation.
