Commuting mileage: 82 XJ650R - 54mpg, 93 GSX1100G 44mpg, 04 VN750 - 56mpg. Older CB750A used to get about 40, 85 VN700 got about 50. Never kept any records on the other bikes. Commute to work is about 90 miles round trip (on lovely NJ roads, Route 9 and Route 18, lots of lights). 6 foot, 220lbs. Juvenile moments tend to lower those numbers dramatically.
