I went on a trip today with a group of 14 and had a blast. We got to see some nice views of the coastline and enjoy a beautiful day.
I logged 194.6 miles on 3.2 gallons of gas. That's like 60 mpg.
I'd been told my bike was capable of it, but it was a shock to actually see it. We held it between 60 and 65 most of the way, not a lot in the way of stop and go driving, so I'm sure that helped.
