Piston Kit Complete 40.25Mm Naraku

PISTON KIT COMPLETE 40.25MM Naraku – fits -> See Vehicle Fitment Tab

High quality replacement pistons for 50cc original cylinders (gray cast iron, piston size 40.25mm) and 50cc Naraku cylinder kits for Minarelli AM engines.

Delivery complete as shown with piston rings, piston pins and piston clips.
The Naraku piston is specially equipped with a molybdenum coating for the sensitive entry phase. This protects the cylinder and piston during the retraction time.

Already from 10000 km it is worthwhile to change the piston with a 50cc 2-stroke engine, rewards one with lower fuel consumption and more engine power.

Not recommended for Minarelli AM engines that have an aluminum cylinder installed from the factory!
The piston size for these cylinders is 40.30mm. The Naraku piston may cause piston noise in aluminum cylinders.
