§ 02 / About this part
What it is
The VERTEX PISTON KIT TOP END Ø 39.50 A, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This top-end kit is the standard fitment for engines with new or low-hour cylinders. It maintains the compression and power delivery required for consistent performance. Replacing the piston at the recommended service intervals prevents skirt fatigue and cylinder damage. The kit includes the piston, rings, gudgeon pin, and circlips. Always check your ring end gap before installation. Ensure the circlip openings face away from the removal notch in the piston. Proper break-in is essential for seating the rings against the cylinder wall and ensuring the longevity of your rebuild.
