This study is undertaken to explore the factors affecting motorcycle-theft. Face-to-face interviews with motorcycle users were conducted to collect motorcyclists' parking behavior and experience of losing their motorcycles. Survival analysis method is then used to formulate the lifetime (the time to keep the motorcycle) as a function of motorcycles' characteristics and motorcyclists' behavior. The study results show that age of motorcycles, location and time of parking, motorcyclists' attitude and behavior are the significant factors to determine the risks of their motorcycles to be stolen
