Strong points of Stage6 Streetrace 50cc cast iron cylinder

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. Perfect road-legal cylinder that will boost overall performance, torque and top speed.

The power is well above the stock cylinder: around 7 hp, that is 3 - 4 hp more than the original! To exploit the full potential of this kit, we recommend combining it with a bigger carburetor (17.5mm or more), a tuning CVT, and a mid-range tuning exhaust like the Stage6 Pro Replica. However, the Streetrace cylinder also works very well with low-profile exhausts such as Yasuni ECO or Tecnigas Silent Pro. With improved acceleration and generally more power, the Streetrace is the perfect choice for anyone who wants more performance but doesn't want to increase displacement.
