Strong points of Stage6 Streetrace 50cc cast iron cylinder
Stage6 can now offer an inexpensive and very durable 50cc sport cylinder. Renowned Italian manufacturer Vertex Pistons is making the pistons for this top quality kit. The cylinder looks unobtrusive and similar to the stock part. Stage6 has deliberately decided not to display the brand name on the cylinder, instead of a logo they stamped "49ccm" on it.
The power is well above the stock cylinder: 8hp, that is 3 - 4hp more than the original! To exploit the full potential of this kit, we recommend combining it with a bigger carburetor, a tuning variator and a sports exhaust.
Scope of delivery and specifications Stage6 Streetrace
- 50cc cast iron cylinder, d=40mm, with 5 transfer ports and simple oval exhaust port
- 2-ring piston, 10mm pin, with piston rings and circlips
- high-compression cylinder head, aluminium
- gasket set
As always, we recommend cleaning the engine before installing a new cylinder and getting a new spark plug and a new small end bearing. Carburetor settings may need to be readjusted.
50cc displacement means that this cylinder kit is street-legal.

Stage6 Streetrace
As the name suggests, the Streetrace series was developed for sporty street use. The Stage6 series includes cylinders and exhausts that deliver relatively high performance, but still function reliably in everyday use.
The Stage6 Streetrace series feature the optimum balance between performance and durability to offer scooter and supermoto riders a high level of riding enjoyment even in everyday use.
How to Install a cylinder on a scooter, motorcycle or moped
The cylinder or cylinder kit is the heart of the engine on scooters, motorcycles and mopeds. It consists of a cylinder, a piston with piston ring(s), a cylinder head and gaskets needed for installation.
The service life of a cylinder depends on whether it has been fitted correctly.
Tuning Level: Sport
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
The products listed under Sport yield better performance than Original parts. They may have technical differences, such as the use of higher quality materials, a larger displacement or a performance-enhancing design. They are suitable for everyday use and have a long service life.
