I was browsing the Statistical Abstract of the United States and I wanted to see how many miles the average motorcycle travels in a year.
If you go to transportation section of the 2004 report (w/ 2002 data), on page 28, you can get the motorcycle mileage by taking the total miles and subtracting all the other vehicles. You get a total of 9.2 billion miles in 2002. Going to page 24, you can get the total number of registered bikes of 4.963 million.
Dividing the number of miles by the number of bikes, you can calculate the average annual motorcycle mileage for 2002 to be 1,854 miles.
I did the same thing for the 2001 report (w/ 1999 data) and came up with 2,505 miles for 1999.
Does this mean anything to anyone in terms of rider proficiency? In just three years, there was a reduction of 651 miles per bike, which has to mean something. What is considered to be the minimum number of miles to maintain proficiency anyways?
