For a sporty driving experience on the road: Stage6 Cylinder Kit 50cc Streetrace cast iron Piaggio AC (Typhoon / Zip), available at a very good price!
Inexpensive and very durable 50cc
sport / midrace cast iron cylinder by tuning expert Stage6. Renowned
piston manufacturer Vertex is making the pistons for this top quality
kit. The cylinder looks unobtrusive and similar to the stock part.

of this kit, we recommend combining it with a bigger carburetor (17.5mm
or more), and a mid-range tuning exhaust.
