First, it's a sport bike, not a "******-rocket". Calling it that is like calling your Rocket a "Fat Slow Cruiser".
Second, yes he is an idiot for riding like that on an obviously unfarmiliar road.
How many of you can honestly say you've never seen north of a ton on public roads? Yes I know, cruiser riders are supposed to hate sport bikers, but the reality is anything on two wheels can has and always will be riden way beyond the legal limits on public roads. As a father and husband I'd mutch rather young men who feel a need for speed go solve it on a sport bike than in a sports car, far less risk to the rest of the public.
Over 50% of all motorcycle accidents are single vehicle accidents.
