So I loaded up my ST and moved to Fort Myers Florida From Suffolk county Long Island Ny roughly 1300 miles. I had 4 bikes on a bike rack my bed was packed my back seat was completely packed front seat was packed as well and I still managed to average 20.1 my best was 20.2 mpg on I95 doing anywhere from 65-75mph with the Ac on for half the trip. The only modifications I have done I put a Fram reusable air filter in The air box and and a cherry bomb M80 muffler with both resonators removed. So proud of my baby !!!
