§ 02 / About this part
What it is
The VERTEX PISTON KIT TOP END Ø 66.40 B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This top-end kit replaces OEM part 54830007300. It sits in the cylinder bore of your 250cc 2-stroke. Regular replacement is necessary to prevent power loss and skirt failure. This is a size 'B' piston, designed for cylinders that have worn slightly beyond the original 'A' specification. Measure your bore diameter to ensure the correct piston-to-wall clearance. The kit includes the piston, rings, gudgeon pin, and circlips. Check the ring end gap in the bore before fitting. Ensure the arrow on the piston crown points toward the exhaust port.
