The purpose of this paper is to design a multifunctional chassis dynamometer for motorcycles to incorporate small size, low cost, easy disassembly, and multifunction integration in one test rig. It can be used for engine testing, CVT testing, clutch testing, flywheel testing, brake testing, and dynamic testing for a motorcycle. This paper will describe how to use this test rig to measure the engine torque and fuel consumption, the speed ratio and efficiency of a CVT, the actuation speed and transmitted torque of a clutch, the inertia of a flywheel, the road loads applied by the brakes, and dynamic testing of a motorcycle.
