i have had motorcycles, four wheelers and even a few three wheelers over the course of 30 plus years. i learned by wrecking one then having to fix it or whenever there was an issue just repairing it. if its something you may not have alot of confidence in doing by yourself then have someone there when you do something. don't hurry to do maintenance or repairs it will come soon enough.
Mental stability notwithstanding, what differentiates the road racer from his "short track" kin does lay somewhere between the ears!!
