§ 02 / About this part
What it is
The VERTEX PISTON KIT Ø 39.50 E, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This E-size kit is engineered for 50cc cylinders with significant wear. The increased diameter restores the tight seal required in the top-end, preventing power loss and difficult starting. Small-bore engines are sensitive to piston-to-wall clearance, so this E-spec is vital for high-hour cylinders that are not yet ready for a replate. Verify your bore measurement with a micrometer to ensure this 39.50mm E-size is the correct fit. The kit comes with the rings, gudgeon pin, and circlips. Always use a new base gasket when performing this top-end service.
