So I’ve ridden to work for 2 weeks, and made 2 site visits that required some highway driving.  1st full tank of gas I only manage 51mpg.  2nd tank of gas I managed 60.1 mpg but was able to ride on the Frontage Road that parallels the interstate for most of the trip where the speed is 75 mph.  (the 250 doesn’t really care for going 75 mph, at least I don’t think it does).)  So I’m still looking at 3x my truck mileagea nd almost 1.5x my non-roadworthy kz550.
