My mpg on my first Uly was in the low 40's, which is where my current Uly started. After 13K miles, on recent trips (mostly in the windy hilly Ozarks) my mpg increased to 50 plus (still 40mpg around town). I know ads had these bikes getting as much as 60. Anybody doing that well? My son said his XB sport bike also increased to 50mpg after 14K miles.
