Stage6 The Biglit_Latn is a 77cc Minarelli AM6

The cylinder was developed in close cooperation with the lit_LatnSlit_Latn experts; by benefiting from their considerable experience of gelit_Latnft mopeds and drawing from their own extlit_Latn technical know-how, Stage6 was able to design a thoroughly convincing new tuning cylinder. The cylinder features a rather basic and inconspicuous exterior, but we all know that appearances can be deceptive. We're talking genuine "Big Bore" here. The cylinder layout is not based on a standard model that was milled open to create a bigger bore, but was designed as a Big Bore right from the start, with matching transfer ports and a bridged exhaust port big enough to support the excess performance. The BigRacing cylinders impress with ease of installation, outstanding performance, and high reliability. Squish clearance is pre-set to a value optimized for the respective engine type. - In terms of output, the BigRacing cylinders knock it out of the ballpark: we measured a wh 23 23 PS and 13 Nm on our P4 test bench using a standard set-up (24mm carburetor, original ignition, racing exhaust etc.). - Port timings are relatively low, cooling system volume is quite large and the piston is a top quality Vertex piston. All of these factors contribute to the cylinder's high dependence and robustness, provided that set-up and adjustments are appropriate. Displacement is 77cc (50mm piston) and is accordingly not street-legal (in many countries). We strongly recommend a reinforced crankshaft with standard stroke. The exterior is a relit_Latn of the original cylinder with a 49cc stamp; don't worry, this is definitely a 77cc cylinder! Note: we recommend to use "long" cylinder head nuts to achieve correct torque when tightening the bolts.
