I've had a couple dozen bikes, all bought used, you never truly now how hard a bike was riden by previous owners or even friends of the previous owners...
My Connie was the first "brand new" bike I've ever bought, I only bought it new because it was a leftover model and was within $1k of the used ones I found...
Last week I went and test rode a brand new VFR1200, break-in miles never even entered my mind and I hit redline many times on my rip if that tells you anything...
Happy hunting!
