2014 Honda Grom real world Gas Mileage

I'm sure this question will come up often once these bikes hit the streets so I figured we might as well get a thread going for "Real World Gas Mileage".

What range/gas mileage can we expect to get with each full tank?

I'm thrashing it but only getting 80 out of a tank, other guys in the UK are reporting 120-130 miles to a tank.
I don't expect we'll really know until people have had them a good long while. Whenever I get something new, my milage is crap until the excitement wears off and I stop riding it like a maniac!

Around 100 miles per tank is pretty awesome! What is the tank capacity?
Tank capacity is listed at 1.45 gal.

Honestly, 100 mpg is great but I just dont care. I think this bike is going to be a hoot. The great mileage is just a bonus.

Are you sure they weren't reporting 120-130 kmh? That would be about equivalent to 80 miles..

You guys should sign up with Fuelly | Share and Compare Your MPG Love that site. We'll be able to track our fuel consumption and get a good real world average for the Grom
I'm sure, UK measure in miles.

Not to rain on your parade but really? Who cares what the MPG is, I what to know what the Smiles Per Mile is.

Do you guys measure in gallons too? An how much are you filling up at the pump at the end of ur 80 miles?
Yeah we measure MPG, I'm lazy and never can be bothered to work it out so just go off miles from a full tank.

Mike is a bit more detailed and tracks it on a App, screen shot he posted a few weeks ago below.

I get around 120 miles to a tank, I am a fat bugger and thrashing it more n more, roughly £5.50 to £6.00 to fill a tank, am happy with that, but I never buy bikes based on mpg anyway, I tune everything I get and thrash it!

Im hoping to do the same.

What app is that?
1 imperial gallon (UK) = 1.20095 standard gallon (US)
1 imperial gallon (UK) = 1.20095 standard gallon (US)
So minus about 20% an well have US mpg according to those app numbers, correct?

Look closely at the mileage numbers...actual odometer readings in miles and fuel in liters. The app did the metric conversion and spit-out mpg numbers, as we know them. IMHO, they're believable.

Whether, or not, things like fuel consumption & extra-legal top speeds matter are an individual's call to make. It depends on how you ride and what you're willing to trade in the name of the gearhead's perpetual quest...more power. The more miles you ride, the more the priority balance shifts toward seamless reliability and cruising range.

Having to stop every 60-80 miles to top-off the tank is no big deal, in an urban environment. If you go out for a long tours of the countryside, doubling the number of fuel stops gets old in a hurry. Rational, or not, I'd have to question just wtf is the point if mpg numbers dropped to a level that's on-par with a 600cc bike...your opinion may differ.
