Because of my route to work (96 miles return, 4 days a week, all year round) and my average speed (being 50mph) I always get 276 miles and then it starts flashing on the last bar. So in theory I could probably get 310- 320 on a full tank.

That is correct, also can be changed to litres I think.

Without looking at the manual, I'd guess it'll show litres used since light came on if you're using metric measures ie km, l/100km etc.

I get about 240 miles on the bike right when it starts flashing.  I also usually have the opportunity to fuel up right away and very consistently the bike will take 3.6 gal of gas.   If I remember correctly it is a 4.6 gal tank.  With that info i figure i have about a gallon left when it starts flashing.... my average mpg is 55-66 so i figure i should have at last 40 miles left but I've never personally pushed to see.

I have pumped up to 4.9 gallons into the tank, even though Honda claims it's only a 4.6 gallon tank. On the one incident when I put in 4.9 gallons, the gauge had counted up to 1.0 gallons (1 gallon burned since the indicator came on). My gauge is overly conservative - it claims to have consumed more fuel than it actually has. I've still never run empty, though I've had some anxiety-inducing miles at the end of rides.

It is possible to put in more fuel than the stated capacity.  You are only supposed to fill it up to the nozzle hole to allow air space for expansion if the fuel warms up before use.  It also allows air space for the tank vent and vapor canister to work correctly.  From 2016 on the capacity is 4.7 gallons when filled to the correct level.  I dont doubt it would be possible to squeeze up to 5.0 gallons into it but you will lose some out the vent as the fuel warms and expands after being pumped out of the cool underground fuel tank.

To achieve 235 miles by the time the low warning starts you only have to average 58.75 mpg.  I typically get 65 mpg on my commute.  I have gotten as much as 76 mpg on a long trip on back roads at no more than 55 mph and taking it easy.  The commute is lower because I have some Interstate highway at 70+ mph and have to drive more defensively/aggressively to deal with people in cages who are distracted or just being a$$holes.

So, yes 235 miles on a tank is easily doable and I would bet most get more than that.

Or 70 mpg if you're in the UK.   :016:

Why oh why do we have different sized gallons, so confusing when discussing mileage.   :153:

I regularly get 85 mpg (uk) or more on my commute. I fill up every 250 miles or so, and Ive never seen the last fuel bar flash. Speeds average between 55 and 75 mph.

I've emptied the tank 3 times (most recently yesterday when I pushed the bike the last 10 metres to the pump - no kidding!).

Once the fuel gauge starts flashing you have about 4 litres left. I say 'about' as once my bike used 4.2 whereas yesterday it read 3.9 when empty.

Fuel consumption (and therefore tank range) varies considerably on type of use - especially cruising speed. I've gotten as much as 530km from a tank, and as little as 317km.

I suggest the use of fuelly at fuelly.com to track your usage and to develop an understanding of your likely range, given how you ride.

And yes, I was embarrassed having to twice hitch a ride in search of fuel! LOL!

Uku383, if keeping your bike fueled is that much of an issue for you, why dont you carry a fuel bottle?  It would be easy to mount a Megatube with a 1.5 liter fuel bottle in it and then you wont have to push your bike or hitch a ride.

LOL - yep that makes sense! However, it's not really necessary.

The first time was me being silly on the way home from work - I pushed the mileage and learnt my lesson.

The second time was a wrong turn on an interstate trip through the outback. I'm now familiar with the route so that won't happen again.

The third time was simply because I was riding faster than I should have on another long trip. I shouldn't ride that fast anyway (I was too eager to get home after riding 1,600km), so I'm happy with that as a reminder to take it easy.

It's no big deal - I know what happened in each case and can fix it. Despite my recent experience, I've refuelled the bike hundreds of times and I've got a handle on the tank range. 😁

Genuinely though - thanks for the constructive suggestion. 🖒👊
