On another thread where I noted that the gas tank is listed as 7.13 gallons capacity, a comment was made that it is not possible to add more than 6 gallons to the tank due to its shape. Yesterday after a long day of riding I put 5.2 gallons in the tank, which for me is the most I've yet done at one time in the 10 weeks that I have owned my 2021 RT. I seem to be averaging about 34 mpg, and assumed that with 7 gallons in the tank I have a real range of about 230 miles. That made me believe that I could safely go 200 miles between fill ups. But if in fact the tank only really holds 6 gallons, that 34 mpg works out to 204 miles, which would mean going no more than about 175 before filling. Yesterday I did about 170 miles and the gas gauge showed that I could still go another 55 miles, but I don't want to count on the bike's fuel computer and risk getting stuck on empty.
