Reference: NK100.90 — Brand: NARAKU

NARAKU piston kit designed for 50 cm3 engines, aimed at riders looking for a complete and ready-to-install replacement. The piston features a molybdenum coating intended to reduce wear and facilitate the running-in process, while CNC machined grooves on the skirt promote continuous lubrication between the piston and cylinder.

• Kit contents: piston, rings, oil scrapers, piston pin, and circlips — delivered complete.
• Nominal diameter: 40.25 mm (check tolerances and compatibility with your cylinder).
• Suitable for Minarelli AM engines and many Naraku 50cc kits (Generic / KSR-Moto, Keeway, Motobi, Ride, 1E40MA, 1E40MB), as well as a wide range of Vintage, Enduro, Roadster, Supermotard, and lightweight Sport models.

Warning: this piston may not be suitable for original Minarelli AM aluminium cylinders due to dimensional tolerances — in some cases, noises may occur. Before installation, check the dimensions and condition of the cylinder. It is common to plan for inspection/replacement on 2-stroke 50cc engines over time (maintenance intervals vary depending on usage).

Compact and complete, this NARAKU kit is aimed at riders wishing to restore or maintain their 50cc engine with compatible and easy-to-install replacement parts.
