I get about 14 km per liter ... don't know how many MPG that is... using octane 95 gasoline and I ride in a really heavy stop-and-go traffic, it takes me 30 minutes to cover 10 km (my commuting distance).
I guess in light traffic or open road the gas consumption will be better.

What's the octane rating?

Not sure who you were asking ???

I use 89 oct....for the first 2.5 years with this bike I used 92.  (1998 M900)
I have been told it makes no difference with my lower compression engine.....
I tried tanks of 87, 89 & 92...doesn't seem to make a difference in performance etc..thoughts???
My people skills are just fine.
It's my tolerance to idiots that needs work.

I just bought my first fill up on my new 696.  With an indicated 104 miles, the low fuel light came on, so I hit the gas station and put 2.5 gallons in.  This is with me doing stop and goes at a parking lot for a few days and some around town riding.

I was asking the op.  But all should post as well..  shows the money saved on lower gasses if it does nothing different

As a rule of thumb you should use the lowest octane fuel you can without detonation (knock...ping...whatever you want to call it).  The octane rating of a fuel is a measure of its ability to resist combustion, not of its calorie content.  The things added to fuels to raise octane ratings are generally not as calorific as the fuel itself, so the higher octane fuels are generally not as calorific as lower octane ones.  That means they make less power per unit mass unless the engine in which they're buring can take advantage of the greater resistance to burning via higher compression, forced induction, or other volumetric efficiency increasing means.

To distill all that down....burn the cheap stuff if you can.  It makes more power and costs less, too!

My new Panigale is getting nearly 40 miles per gallon.....during the break-in period where I can't rev it over 6000 rpm.   ;D

What octane are you running?

87.  The owner's manual recommends 90 or higher.  However, cylinder pressure is reduced significantly at altitude (my driveway is at about 5400 feet) due to less efficient cylinder filling, so I can get away with lower octane fuels.  My turbocharged Mini still likes at least midgrade, but the normally aspirated Duc doesn't seem to care.

My old M900 has a 4.2 gallon tank, and gets about 48 mpg average (46 if I'm mostly around town, more like 50 if I'm out for a good ride -- it seems to be most efficient at speed).  So I can get over 200 miles on a tank; I normally start looking for a gas station at 175 miles.  The low fuel light used to come on at about 160 miles, giving me about 40 reserve, but I quit trying to keep the fuel sensor working years ago and just use the tripmeter.  I ran 91 octane (U.S. measurement) for most of its early life, but the first time I had the heads off (at 122K) I found some carbon buildup, indicating I was running too high an octane, so I switched to regular (87 octane U.S. measurement), and have run that since without problem.
