Below is the 2020 Florida Statutes – 316.2095 Footrests, handholds, and handlebars, para (2)
“(2) No person shall operate any motorcycle with handlebars or with handgrips that are higher than the top of the shoulders of the person operating the motorcycle while properly seated upon the motorcycle.”
I guess it really boils down to how long is your torso, because it is measure from the rider’s seated position to the rider’s shoulders. Change riders and the handlebars might have to come down or could even be raised a bit…
Then there is the issue of “Pull Back Handlebars” where the tubes rise up and then bars drop down, like in the photo of the Servi-bike in the previous posting…
I’m 5’8" and one of my riding buds is probably 6’2". If we lived in Florida and if his handlebars were at the state’s maximum height for him and I rode his bike, it would be illegal for me…
