Big Bore cylinder kit Ø47 developed for air-cooled horizontal Minarelli engines. Designed to transform a 50 cm³ block into a "big bore" setup, this kit combines a robust cast iron cylinder and a Ø47 mm piston mounted on a Ø12 mm pin. The piston features a "Racing" compression suitable for light tuning and a more dynamic riding style.

• Cylinder: cast iron, assembly-ready finish.
• Piston: Ø47 mm, aluminum material, Ø12 mm pin.
• Rings: 2 rings included.
• Type: Big Bore for air-cooled horizontal Minarelli engines.

This kit is aimed at urban riders looking to tune their 50 cm³ scooter with a Minarelli base. It requires proper installation and adjustment (timing, carburation, exhaust) to fully utilize the new displacement. Check mechanical compatibility with your model before installation.
