Motorcycle have become very popular transportation nowadays. There are several ways of classifying motorcycle into different types of categories such as according to the engine displacement sizes, type, usage, mechanical function etc. Aside from manufacturer’s classification, which is based on the engine displacement sizes, most of them are subjective. Due to the variations, research related to motorcycle are uncoordinated. In addition, consistency and reliability of data collected are necessary since the field of research is vast. This paper aims to fill this research gap by proposing a standardized method for motorcycle nomenclature system, which is a classification based on a motorcycle cockpit design.
