My riding style involves 5 to 10 mile jaunts to local off road areas. I just add fuel from a can I put either 89 or 91 octane in (usually 91 since I use it for small engines and the dirt bikes). So I have never really gotten a good idea of how many miles I get on a gallon of gas. My guess is 60mpg at best since I tool around off road having fun in the steep climbs and wheelie way too much
And I also geared it down with a 51T rear sprocket and dropped a tooth in the front as well. And I don't really believe the odometer anyway. I may never know!
