Hey JP, thats gonna be a hard one to answer. Really its different based on usage and how you ride. I can tell you that Rubicons are typical Honda's that are very dependable and take a beating without much trouble. Compared to other quads they are not in the shop all the time. But your question would be different from different type riders. Maybe I can answer better if you say how its generally riden, how often, where stored, etc.
