Stage6 Streetrace 77cc cylinder kit for Minarelli AM6 engines.

The Streetrace cylinder made its name on scooters, Stage6 has taken the knowledge gathered and applied it to geared mopeds. The 77cc cast iron cylinder has a 50mm bore, 5 transfer ports and a simple exhaust port. A twin ring piston is included along with a high compression aluminium cylinder head. Performance is increased from the bottom to the top of the rev range.

A 21mm carburettor, mid-race exhaust, reinforced clutch and racing crankshaft are recommended. A 3% oil mixture is also recommended.

As usual with big bore Streetrace cylinders, Stage6 has stamped "49ccm" on the cylinder for official amusement.
