MotoForce Racing 70cc Cylinder – Piaggio AC

Reliable and budget-friendly 70cc cast iron cylinder kit for air-cooled Piaggio engines, ideal for everyday use on scooters like the Piaggio Zip.

This kit is a great upgrade over the original cylinder, offering more power while maintaining solid durability. The cast iron construction ensures long service life, while the design with 5 transfer ports and a simple exhaust layout provides strong and consistent performance.

Equipped with a 47 mm 2-ring piston and a high-compression aluminum cylinder head, this setup delivers approximately 6–9 hp, depending on the exhaust used. The focus on torque improves acceleration and reduces the need for high RPMs, helping to preserve engine reliability.

For optimal performance, it is recommended to pair the cylinder with a 17.5 mm carburetor, a sport CVT, and an exhaust like the Stage6 Pro Replica exhaust.
