I'm looking at buying a bike for the first time and have just been wondering....how much abuse can bikes really take? Miles-wise, etc. Since I'm eyeing used bikes, VFR800FI's specifically, I'm just wondering, how much is too much?

Oh yeah, might as well throw it in.....What is basic maintenance like on sport/sport-touring bikes? I, of course, wanna be riding more than worrying about maintenance schedule and shit.

Thanks all.
