I filled the fuel tank on my Rebel CMX500H today.

The fuel gauge had 1 bar showing and 129 miles since picking up the bike from the dealer.

It took 1.754 gallons of 10% ethanol gasoline, 87 octane.

If my calculations are correct I got 73.54 Miles Per Gallon. When I have the engine broke in to my satisfaction, and ride a little more aggressively, I would expect the MPG to drop somewhat. All of my other bikes average in the low 40 MPG with my riding style.

Ive found my first bar disappears rather quickly..maybe 20-30 miles and it's gone..and when the last one is blinking I have had .8-.9 gallons left. I've been resetting the trip to get a better idea of how much I have left as I thought I was almost empty a couple times and found I had almost a 1/3 of the tank left!

I got my bike with two bars on the fuel gauge. I rode it for about 70 miles and it dropped down to the 1 bar and started to blink. In California we have dumb rubber boots on our fuel bump so I had to hold that as I was filling up my bike. I spilled a bit of gas. *facepalm*. In the end though I filled it up with like 2.2 gallons when it got to the top, including the spilled gas. The tank itself is rated at 2.9 gallons. So I probably had like 40 - 50 miles to go before it ran empty. But.... that is a scary thought lol.

Yesterday was the first time my fuel gauge was low enough to start blinking. It started blinking somewhere around 140/145 miles on the trip odometer, and it was close to 160 before I stopped to fill it up... still only took 2.3 gallons to fill up. Averaged ~65mpg for this tank.

I have found in CA if you put the nozzle in straight down the middle through that hole and up against the little stop bar in the tank, you can fill it up without pulling back the vapor sleeve. Then it'll click off a little too soon, so then just squeeze the trigger a little bit and it will dribble in the last 1/2 gallon or so. Been working well for me.

I'll have to try that. Brand new to motorcycles and only needed to fill it up once so far, but it sure as **** gave me a headache lol. I was like nothings working until I started messing with the plastic boot.... that's when the fun began. I gotta give my bike a thorough washing this weekend.

When it starts to blink you've reached your "reserve tank", wich has about 2 liters left of fuel.
Oh thanks!! I was wondering how to get to the "reserve" tank. :) so a little less then half a gallon when it starts blinking equates to make sure gas is within 20-30 miles depending on your economy huh?

and upon reading more of the thread, I realize people are having some thoughts that maybe the reserve is a bit bigger then a half gallon?

Today my fuel gauge started blinking at 161 miles on the tripometer. I gassed up and it took 2.153 gallons.

If my math is correct I got 74.59 MPG. This may be the most fuel efficient motorbike that I have ever owned.

This only works if you can be sure you filled to the same spot everytime.

Honda Rebel 500 2018 Maximum Gas Mileage

Yesterday was the first time my fuel gauge was low enough to start blinking. It started blinking somewhere around 140/145 miles on the trip odometer, and it was close to 160 before I stopped to fill it up... still only took 2.3 gallons to fill up. Averaged ~65mpg for this tank.
So my honda is the 500 2018 abs model. About 80% of my driving is done on the freeway at an average of 69mph, while the remaining 20% of my driving is done in the streets at an average of 30mph. My motorcycle is practically brand new, its got 500miles on it.

Today I got a total of 186.6 miles out of the entire tank. The last bar of the fuel gauge started blinking at 147.5 miles. That is the reserve tank. The reserve tank gave me 39.1 miles when it started feeling like it was about to stop. At that point I went to the gas station and filled the tank with a total of 3.014 gal. I did spill a tiny bit of gas, and I know the tank is only suposed to go up to 2.9 gals. But regardless those are the numbers. I try not to drive aggressiveley in order to obtain more mpg out of my tank. Let me know if anyone has gotten any more than 40 miles on the reserve tank!

Those are very impressive numbers. Impressive being an understatement. Do you mind sharing how you tested and risked going an additional 40 miles and somehow ended up right at the gas station when you felt the bike couldn't go any longer? Or did you literally run in circles around the gas pump to test this?

His numbers are pretty average.
