Well, the whole mentality of "when" not if your gonna crash comes from the agressive riding style of sport bikes.
Sure you can own a sport bike for ever without ever laying it down, and since you have a bike now, the chances of you never crashing are good.
But the whole reason for wanting a sportbike, is the agressiveness, and if you start riding it agressively, pushing the bike to its limits,(wich is what its designed for) then the chances of a get off,(crash, fall, etc) are greatly improved. and yes the majority of people who ride sportbikes agressively will go down at some point in their life, the harder you push it, the more likely.
Their are few people who buy sportbikes just to cruise on, but some do buy an uncomfortable, cramped seated, agressive sport bike just for the looks, and just cruise.
