Possibly if all down hill, no luggage, no passenger.
And easy on throttle.
I sure hope 1 could. I would do it to mine in a heartbeat.

Might be possible under 300 miles of very favorable conditions, but highly unlikely. Just wondering why would you try it. Bring extra gas or do an accurate mileage check X 6.2

my average is between 36-40 depending on how fast and hard i ride. On a trip up to tenn i set cruise control at 75mph and was getting 39 - which is my best. That puts my tanks around 220 miles. I did 3 non stop 200 mile tanks in a row, i dont think i could have sat on the bike for that extra 100 miles like you are asking

I really doubt it. On the I5 to and from California with a stock 96 ci FLHTC and cruise from gas station to gas station I can do 325 kilometres (about 230 mi off hand) before I need a fill up.
You're chancing it brother.

Batwing Harleys can get 50mpg+ if running premium "pure gas' ride between 60-65mph on flat ground with no headwind etc. If you are running a tuner/XIED"s, A/F etc it wont happen.

I disagee.

Running a tuner, and right hand management, WILL improve your mileage.

The key is keeping the right hand under control.

My '11 FLTRU, SE intake, RUSH true duals and TTS tune, I pulled 48mpg 2 tanks in a row on a trip.
