Doesn't matter how sensible you are buddy, I had been riding for years and always got away with a light scrape here and there. I had every type of bike you could imagine and the accident that nearly ended me was one where I was going 25mph and someone cut straight across my path!!!
Be sensible and get yourself a tamer bike for a year or two, the power from a 600 or 750 sport/super sport bike is addictive and irrespective of how sensible you are, you will use that power.
You need to spend time understanding how a powerful bike corners/stops/reacts in different situations.
Not trying to be a know-it-all but too many novice riders have come unstuck when finding themselves in a situation that they weren't prepared for.
