I started riding when I was 22 ( out of college, could buy my own bike.)
'92 Seca II - 38,500mi
'87 VFR700 - 8,000mi
'92 VFR750 - 69,900mi
'00 Busa - 30,500mi
'00 DR650 - 3,000mi
'91 CBR600-3,000mi
'97 Blandit- -3,500mi and counting
The Seca II, VFR750 and Busa were my only new bikes.
From 1992-2002, I commuted to work extensively by bike... and I didn't have kids for the first few years outta college, so I rode a lot.
I beat the VFR mercilessly everyday, abusing the clutch to get a first gear wheely, always running into rev-limiter, many times a day.
I only replaced two headlight bulbs, and a nylon washer around the speedometer pickup. It was unfreakingstoppable.
Come to think of it, none of my bikes have had any issues beyond a headlight or taillight. Pretty remarkable for how little I maintain them.
