I've had my bike for about 13 months now.  The 3 times I've had the alert come one there seems to be 1 US gallon left in the tank.

ETA:  Mine's a 2014 bought new in 2015.  About 8400 miles on the odometer.

That US$2.07 per US gallon would be approximately (US$2.07 / 3.7854) US$0.55 per liter. Our Canadian currency exchange rate with the US dollar is presently 1.32 %. So I that liter in Florida would cost a Canadian about CAN$0.73 with the credit card currency exchange.

As I get $0.12 off @ liter with my credit and gas saving cards, I pay ($1.00 - $0.12) $0.88 @ liter. That's CAN$0.15 @ liter more than the equivalent price in Florida. The difference is probably our government taxes hidden in the price.

 :069:What is really strange is that we export over 3 million barrels of oil to the US every day, but import oil and gas from other countries.

<begin rant> What is really strange is that a gallon of diesel takes 1/4th to 1/6th the refining (read as : refining cost) then a gallon of premium does, and its more expensive then the highest octane gas at the pump ???  :087:

Some retired oil industry bigwig once said to me that since 90 % of the consumer vehicles here in the US are gas and diesel is primarily used for commercial trucks, ships and trains etc, that it is easier for the government to tax without our short sighted consumers getting in an uproar (read as : Panties in a wad) since the cost is spread over millions of end products transported and is not as obvious to the end user as is the sign at the gas pump. People will spend $2.00 in gas to drive to a pump that is 2 cents per gallon cheaper. Oh and then go into the gas station and spend another $10.00 on drinks and snacks lol . I'm as guilty about the snacks.(read as : shock preload set to 5) :138: <end rant>

I use to chuckle to myself standing behind people who complained about paying $1.25 for a liter of gas; but thought nothing of paying $1.50 for half a liter of bottled water, something that is available from any tap.

Back on topic, I've found that using the bike as a commuting tool (slow speeds, filtering, numerous gear changes) the mpg has gone right down. I would never risk hitting the reserve.
For a daily 60+ mile commute I'm topping up at least twice a week to ensure I don't come unstuck given my M3/M25/M4/Westminster/City routine - petrol stations I pass can be counted on the fingers of less than half a hand....

I recently had occasion to check my fuel range comparing what the dash indicators say (known to be wrong) versus the real world.  I was on a bit of a trip home and decided to "push" the fuel to see if I could get home without refilling.  The manual says when the fuel light starts flashing there are 2.8 litres remaining.  I got all the way home and then decided to see just how far it was to empty.  I put  litre of gas in the pannier and  continued to go about my rounds over the next couple of days.  I managed to push it to 505km (previous trip was 90-100 kmh cruising) which was nice to know.  I added the litre, rode 1.5km to a gas station and and topped it up with 16.2L : Total 17.2L.  So Honda's claim of 17.3 is pretty close and all of it is accessible (my KLR still had gas in the right hand side of the tank when the reserve ran out).  The manual says when the reserve light starts flashing there are 2.8L remaining but my indicator showed 4.2L when the bike quit.  The "total fuel consumed" indicator showed 20.4L but we have already established that the tank only holds 17.3L - so that indicator is useless.
I wondered in a previous posting if Honda had rectified this error in the '16 model (mine's a '13).  I suspect not or I'd have heard about it.
Anyway I know now that I can push it to about 500km if I have to (nice!) and that once the reserve starts flashing, I can go to 4.2L on the indicator, not 2.8.  This knowledge relieves a lot of my "range anxiety".

Today, my 2013 Cb500x took ~4.1 US gal to the fill ring, after reading  0.7 into reserve.  This was at 328.9 miles.  I thought it was on fumes, but I had a half a gallon left.  I then put in another 0.2 Gal above the fill ring, as is my habit, leaving a fair sized bubble still in the tank.
I long for the old fashioned gravity fed fuel tank.  You knew w/ some certainty what was left in the tank, when you flipped to reserve.

Today I noticed the fuel meter flashing which was worrysome. The digital number displayed was hard to read while riding and kept changing. So I stopped at the first gas station I found.

When I stopped it read 6, I assume that meant .6 litres used since it started flashing. I topped up with 14.0 litres of fuel, so there was 3.3 litres left in the tank. As I average 29 kilometers per liter, I could have travelled almost 96 more kilometers.

It's to bad the display doesn't shown the amount of fuel left. If it had shown 3.3 liters, I could done a rough calculation while driving 3 x 30 and known I could driven at least up to 90 kilometers without all the worry.  :012:

My usual gas station was far closer than that. At it I would have saved 12 cents a litre with my gas saving cards. Should I sue the Honda Corporation for the (14 x .12) $1.68?  :210:

I'm a new CB500X owner, but my two fill-ups so far indicated the following averages:

Low fuel flashing begins at ~229.5 miles traveled (statute, not nautical miles for any sailors here).
Miles per gallon (US): 64.4 MPG
Estimated miles remaining after the fuel flashing begins: 64.8 miles
Estimated range per tank: 294.3 miles

These numbers will be refined as I put miles on the bike.

Definitely, they've got more money then you have ( I guess ).

REServe Explained I think? USA
When the last light starts flashing the numbers start counting up. At 0.0 you have one gallon of gas.
Depending on your driving habit will determine how far you can go before running out of gas. 40-65+ miles

ie: the tank holds 4.62 gal
On one occasion the number read 5.9 and when I filled up it took 3.7 gal with a difference of .89 gal left in the tank.
