on the topic of street bikes, i took my good friends gsx-r1000 out for a spin on some open track, good fucking lord, 120 at the flick of a wrist and it doesn't even feel like you're moving fast because theres so much left. i got scared at 140, just the thought of what a crash would do.
i ride dirtbikes on a semi competitive level, and just one day on that bike is enough to keep me from buying a street bike. the power is intoxicating and its impossible to ride it slow and thats why i know i would get smoked by someone backing out of their driveway or switching lanes.
