When there was a car accident involving a motorcycle, it is crucial to determine the velocity before the collision. The sliding motorcycle after a collision finally come to a halt because of kinetic frictional force that exists between the moving objects and the roads. If we know the total sliding distance of a motorcycle we can calculate the speed just before the collision by a simple physical formula. For that we should know the sliding frictional coefficients of the motorcycle on the sliding surface. In this paper we inferred sliding frictional coefficients of motorcycles under various conditions by pulling it. As various sliding conditions, three kinds of sliding surfaces, two kinds of pulling velocities and two kinds of motorcycles are applied for comparison. The results revealed that the factors are highly dependent on the sliding surface, and not as much in the conditions associated with velocity and motorcycle model.
