Cylinder Kit AC Athena Hyper Race 10mm 70cc Minarelli Vertical

Athena is pleased to announce an absolute first in the world of Minarelli vertical AC engines. The intake and exhaust ports have been completely redesigned: by analyzing the engine's thermo-fluid dynamics, overall performance has been significantly improved in terms of power and torque, reaching new levels for the first time. The intake port has been redesigned, adding a fifth CNC-machined port to allow a higher gas flow rate entering the combustion chamber.
