I took my trike for a little romp the other day, about 250 mi. Most of this was on freeways, kept it at the speed limit, 70 mph. I did this just to check the gas milage, and for some bike time of course, I averaged 29.6 mpg. WAY off of what they advertise. What kind of mpg is everyone else getting? The HD site says 48 highway, 33 city.
