Apparently, 199 is it..

for maximum on a warm day for distance on one tank on my 1997 California. So about 40 miles after the red light comes on.

And why doesn't the Guzzi roll down hill toward the gas station?

[Sasquatch Jim]

Because the gas station is always uphill from where one runs out of fuel , always , no exceptions .

It's the law.

Yes, the the grade of the hill will seem inconsequential but it is just enough to have you heaving in three feet.

Best thing about a Moto Guzzi is that someone will always stop to bring you gas about 10 minutes after you call for roadside assistance.

Same numbers for my '09 Stelvio, although one cylinder was still sputtering as I stopped at the pumps.   Didn't have to use the key to cut it off.

Good numbers to know .... reduces my excuses for the future, though .... !
