Mine makes some noise not enough to concern me yet. I change all fluids forks,trans, rear end every other year I never believed in lifetime oil in these components. I know some people think that's a waste. I paid alot of money for this toy and I have no problem with preventative maintenance over and above factory recommendations. I find myself in places I don't want to be stuck in. This is still my favorite toy I have at the moment. Richard Have fun.
