Recently, application of a Multi-axis road simulator has been studied to improve reproducibility of vehicle running, however the system is complicated and expensive due to the large number of vibration axis. Therefore, it is necessary to clarify the evaluation object and balance the evaluation accuracy with the test efficiency appropriately. In this study, we have developed a method for efficient fatigue reliability evaluation of an off-road motorcycle with the road simulator. We focused on the simulation of a jump section of a track because it had been clarified that the fatigue damage in the jump section accounts for the most of the fatigue damage to the vehicle in one lap on the track.
