I have a 2002 Legend GS 700 which has DPM. 10mpg would be extremely low and would work out to about 100 miles on a tank of gas. My normal range would be from 12 to 15mpg, depending on the type of riding and weather conditions. Two of my friends have the Legend SE 800's with the Tour Buddy gas tank installed and I can travel the same distance on a tank of gas and my sled does not have the extra tank.
Once I hit 100 miles on a tank with my '02 700 adrenaline w/dpm I start looking for gas!. 10 to 12 mpg would be my best guess with normal riding. Hammering across big lakes and your looking at 7 to 8 mpg.
