My AN650 mileage has varied between a low of 38 mpg and a high of 51.6 mpg. Typical mileage is about 47 mpg. I get my worst mileage loaded for touring and cruising at 80 - 85 mph. I've gotten 51 mpg riding tight curvy hilly roads in the South Dakota Black Hills & through the rural Arkansas highways in the Ozarks. Basically, my 650 likes moderate cruising speeds. Start cruising at 70 mph or higher and the mileage dives. I like brisk acceleration, so I doubt that I'll ever see anything much over 51 mpg. I wish it did better on the trips. Out here in mid-America you kind of have to run at 80 mph when traveling through the plains - and the CVT seems to lack any overdrive capability at those speeds.Edwljoseph said:My 650 has 4,300 miles on it. The mpgs go between 44 low to 50 high. Avg is about 46 mpg. Today i went for a 250 mile ride which was composed of good seconary roads and a few highways. When I filled up it took 3.2 gallons to go 180 miles. That is 56.25 mpg. What happened.
