I have a 2018 FX. My dads house is about 7 miles highway and 5 miles off, i use about ~25% round trip doing 70-80. I bet I could get close to 40 miles from 100-0. The 14.4 bikes will be about double, so 80ish miles highway (numbers say 90, thats prob more like it). I've found the zero published numbers are pretty accurate.
