Replying to I want a sport bike

for some reason, ive recently decided that i really want a sportbike. anyone on here that owns one or knows alot about them that can chime in? is this just really stupid in college and i should wait till im outta college? i keep going back and forth between telling myself it would be fun as hell and telling myself it would be stupid and irrational. my dad had 2 harleys back in the day, so i know more than the average idiot about motorcycles in general, but i really dont know much at all. i think id just buy on craigslist (only way i could actually afford it), but is that just stupid too?
