What would you get? Let's pretend that you're already somehow completely skilled in motorcycles, skilled enough to ride a 600cc sports bike at it's full potential.
Me? I would go for a Ducati Monster. Lighter than most sports bikes, 600cc V2, revs right up past 9000. That and, my god just look at it
If that was mine I wouldn't ride it, I would sit and stare at it all day.
