The Malossi Sport 70cc cast iron cylinder kit for Piaggio LC scooters — including Gilera Runner and Piaggio NRG — delivers race-proven performance engineered for both track endurance and street reliability.

Cast iron construction provides superior wear resistance and heat dissipation, while the dual-ring piston design extends service life significantly compared to single-ring alternatives.

Expect responsive torque and power delivery, with acceleration that shines when paired with proper clutch tuning. Paired with a 17.5mm carburetor and performance exhaust, this kit generates approximately 7–10 hp across a broad powerband, making CVT weight adjustment straightforward.

Note : 70cc displacement requires no road approval.

Kit includes :

• 70cc cast iron cylinder with 6 transfer ports and oval exhaust port
• 2-ring piston with 12mm pin
• high-compression head
• carbon reed petals for stock reed valves
• complete gasket set
