Based on the odometer, I get anywhere between 33 and 44 mpg. 44 was the best - all highway. The lowest all city/2-up. I average probably 38-40. BUT, I've found out that my odometer reads fewer miles than I actually go. I don't have an exact amount yet (I will soon) but I estimate it's 12% off. SO, I would have to add 12% to all my calculations. If someone else's was off that much the other direction it could be 20-24% difference. Someone who says they get 50mpg might only be getting 44 equal to my 39 (corrected to 44).
There's really no clear way to compare unless everyone calculated exactly the percentage their odometer is off and compared "corrected" figures. You can either use a GPS on the highway OR note milage at a mile marker, ride 10 miles, and note milage. When I tried it the first time, I went 8.9 miles indicated for the 10 miles. I would have to add 12% to my indicated to get true milage. You can use an average of one tenth off = 1% off. But if you're less it will be a little more and if you're over it will be a little less percentage. Try it and see what you come up with. I would love to get a true mph comparison with others.
