Starting from the piston first! To achieve maximum limit, of a cylinder in the 130 cc class, 54.4 mm diameter piston applications. Through Bore up method, now so 127.3 cc cylinder capacity. Self-dong

With a piston diameter that is larger than standard, suction and exhaust valves are also adjusted. For this BEAT, relying on the valve pocket Honda Sonic. But the previous Sonic valve diameter 28/24 mm re-adjusted.
