My best MPG (UK) was 104 over 3 days commuting  276.1 miles with still 1 bar of fuel left. I commute every day (97 miles), all year round and my average mpg is 95 - 98 in the summer and 92 - 95, in the winter. Riding country lanes, motorway and city to work. The 471cc engine is perfect for this commute.

It's an impressively frugal engine.

What set this bike apart for me was the on board computer was actually pretty much bang on with the mpg in real world terms comparing with Fuelly after the bike was fully run in from new. My Tracer 900 (with 5000 miles on the clock) is way off. Dash says 53, Fuelly says 44.

I normally find the onboard computer on my 2017 bike under-reads by a few MPG.

My record earlier this year out of a tank was 101 MPG (UK). Much like Mark, I normally get around 95-98 MPG. TBH, when I was looking into buying a CB500X, I didn't realise they're this economical. Amazing efficiency!

I wonder if the 2019 display allows a reading which goes higher than 99.9MPG?  :016:

Crazy isn't it, there are 125's that aren't much better. I was getting about 73 mpg on my short 12 miles round trip commute into the city, which is pretty amazing.

I'm running e705 tires. No knobbies and try to stay below 5k on rpms when riding around.

Maybe crunch some numbers yourself then. Sounds like the bike's reading is off.

I always do my mpg calculations online as the on-board computer is always wrong.

The only catch to this is you are relying on the onboard odometer to be correct...  There isn't a way to get an absolutely correct MPG reading without calibrating the onboard odometer, so the calculation will always be a ballpark figure.

The only thing that really matters is the $ per month it is costing me compared to my other vehicles.  Since my other commuter is a diesel truck, the difference is both in the mpg and the fact diesel fuel costs more than gas.  I have enough history on both vehicles to be able to calculate I save on average $109 per month in fuel commuting on the bike.  This doesn't even factor in the thrill of riding the bike!

Not only in fuel, but consumables like brake pads, tires, etc. Motorcycles for the win.

Got to agree with the costs issue relative to normal vehicles. My weekly commute is circa 600 miles. My auto car 2L engine struggled to give me 30 mpg. Moved to bike, not only am I getting upwards of 70 mpg, Im saving literally hours of time.

Upshot, not too concern about running costs as they will always be less that the car, plus its more fun, even in this cold weather, will be better in the summer!

Oh, and like some others, I tend to ride mine like its stolen, but I also find I get more throttle control at the higher revs, especially as its less torquey coming out of our always greasy roundabouts!
Just adding my few words!
If it aint broken, it will break, best learn how to fix it!
