No 77cc (or commercially called 80cc cylinder kit for Minarelli horizontal engine, as far as I know. Some high torque alternatives (for the 70cc category) for an Aerox are the Polini 70cc Sport (PN code:166.0083) or the Black Trophy (PN code:T9931310) from Top Performances. Both are iron cast cylinder kits, which develop good low-mid torque, especially the Polini one.From a reliability standpoint, Black Trophy seems to be unbeatable.

The commercially available 74-80cc kits for Minarelli horizontal will trigger other costly inherent modifications, as they do require long-stoke crankshafts, with 12mm gudgeon pins, etc.
