This 50cc cylinder kit from Stage6 offers you the possibility to achieve a higher power output without increasing the bore size.

The cylinder is made of aluminium and equipped with a oval exhaust port (not bridged!). It is one of the most powerful cylinders in its 50cc class (will require matching to an appropriate exhaust).
Its selling points include good acceleration and ability to build rpms as well as excellent heat dissipation and long lifetime.

Comes complete with head, piston and gaskets.

Use with short reach BR9HS spark plug
