My friend ... who is also my salesman, told me the average mileage on a Harley trade in (here in town) is 4500 miles and about 4 years old. I bought my 2011 Ultra with 2000 miles on it in 2013, traded it for the 2015 tri Dec 2014 with 12,500 miles on it ... the tri now has 3000 miles on it .. I love to ride,
