How long on average in miles is the life of a sportbike used primarily for commuting but riden for pleasure, Mild riding never raced and professionally maintained with regular service and care? This is a curiosity question. I never race or stunt but I do enjoy a nice canyon ride about 1 or 2 times per month. Commute daily on the bike and have it serviced regularly at the recommended intervals. I have always been this type of rider but usually trade in and get a new bike right around 10-12K and have never traded because of problems with the bike...So what are the experiences of other riders as far as how long thier sportbikes last?
