This paper is to study and analyze for manufacturing of a vehicle using with 125㏄ engine. The first, we made the manufacture a car using with material of the carbon steel pipe that was 27㎜ in a diameter and 2.9㎜ on thickness. But all frame manufacture of a car as knuckle and power-train system made the same pipe, the acceleration power of a car was very disadvantage driving. Therefore this problem must improve accurately. The second, the sprocket teeth ratio of power-train system adjusted on 4.61:1 that the number of tooth processed with 13 tooth on small gear and 60 tooth on large gear. It verified the fact that the gear ratio did to optimize the driving condition on kunsan contest in 2015. The third, the suspension in chassis system softly controlled the hardness of front side and stiffly adjusted the damping force of rear shock absorbers. It was knew for the driver to advantage driving his a car. The steering system largely could make better use of a space when moving in front of pedal. Also, the brake system was improved to distribute the accurate brake force by two clutch master cylinder.
