I do not want to claim something that’s not true so with that let me explain that i have faith that my first stock 74mpg is probably pretty close but my last post of 105 COULD be flawed. now i say that cuz i just got my gear swap and tried to figure what a combined fuel consumption was and noticed how i could be off by a few ounces while filling up in the garage. even using a turkey baster trying to find that exact reference point is hard (btw combined before gear at 45mph for 1/2 trip and 55 after gear swap for 1/2 was 89mpg 33.7mile trip). SO i will post my mpg's only after a good 150 miles that way maybe 1 to 3 ounces off won't be too variable. best thing i think other than disconnecting gas tank and riding with a graduated measuring cup. i bought this bike just for going back and forth to work no offroading. the reason i favored this bike was due to its advertised mpg, but i want to keep it enjoyable, now eventually i might get more extreme but i'm still trying little steps so please don't anyone take me wrong or like i dissed ya. i think next will be a shield or see if i can find a flairing that could include lights and cover handle bars, check mpg, then see what i can do with front fender check mpg. some time do a tire swap away from these knobby ones check mpg. also put a tach on this thing as for posture, right now i travel 16miles one way to work 14 at 55mph 4 lane rural highway basically flatland, i ride with my feet on passenger pegs it feels good with just a little forward lean. i don't think i can stand too much of the "crotch rocket" ride,( School of Hard Knocks has taken its toll on my back
) btw I ain't downloadin no spell checker i know i need it though
