A low mile original is a valuable bike, only if it looks like a low mile bike. If the speedo says 100 miles, but the bike looks like 10000 miles of hard road, then we'll be calling BS. Low miles, but the nubs are worn off of the footpegs, paint is rubbed off the side covers, tires are off brand, grimey engine, nics & scratches..? A speedo can be changed out, reset, or disconnected so as not to read miles traveled.
A nice bike is a nice bike, even if it has traveled many miles. High miles and good condition shows that someone has loved it all thru the years, and miles.
