Most fun from motorcycles comes from accelerating and turning. You can accelerate and turn on something other than a motorcycle and preferably not around cars.
Most of the problems encountered by motorcyclists are encountered by bicyclists. Cagers who aren't paying attention, gravel on the corner, hitting stationary objects with your rag-doll body, and overestimating your skill. Motorcycles just add more speed to the equation, and have to play in the same arena as cars.
