This paper presents the motorcycle inspection standards of electrical system, frame & body, lights and speedometers. 187 real-world motorcycles are visually and mechanically inspected according to the developed inspection standards. The non-compliance rate of inspection standards of the lights is 23.7% and main causes are damage, tinting, painting and coloration of head-lamp, number plate lamp, front-rear position lights, stop lamp and direction indicators of motorcycles. Also, 28.4% of motorcycles are dropped from the luminous intensity inspection standard. Motorcycle electrical system cannot be visually inspected. The motorcycle inspections standards are improved reflecting 187 cases of real-world motorcycle inspection results.

The climate change due to the increased consumption with fossil fuel and rise of the oil price have been serious global issues. Automobile industry consumes 30% of the oil every year and causes air pollution and global warming by the exhaust emissions and carbon dioxide ($CO_2$). The demand of two-wheeled vehicle increases every year due to the parking and traffic problem caused by the increased automobiles in the urban area. Approximately 50,000,000 two-wheeled vehicles were produced in 2008. The development and sales of the hybrid two-wheeled vehicle industry become active due to its increased market demands. In this paper, the change of the motor and battery efficiency, driving distance, hill climbing ability with the change of the motor capacity was analyzed. Simulation of the peculiarities in urban driving schedule(World-wide Motorcycle Test Cycle(WMTC), Manhattan driving schedule), constant speed(10 km/h, 35 km/h) of small electronic two-wheeled vehicle was also carried out. Through the simulation result, appropriate capacities of the motor and battery for urban driving was acquired.

In the last several centuries, humankind have been experienced the material abundance with a development of technical civilization and being industrialized quickly. During the process of this, environmental pollutant have occurred naturally so that humankind have more interests for environment pollutant. Air pollution caused by exhaust from a car is very harmful for human. Most of exhaust from a gasoline engine are $CO_x(CO+CO_2),\;NO_x(NO+NO_2)$, and THC(Total Hydrocarbon). The method to remove these kinds of noxious gases are so many thing such as the three catalysts, $NO_x$ catalysts, Filter and so on. However, although air pollution caused by exhaust from motorcycle have also occurred very much, there is no regulation for motorcycle. In this paper, we studied to remove $CO_x(CO+CO_2),\;NO_x(NO+NO_2)$, THC exhaust from a motorcycle using non-thermal plasma In the result, $NO_x(NO+NO_2)$ concentration was decreased approximately 70% and THC(Total Hydrocarbon) was removed about 40%.
