Really boring unsurprising stats on fuel consumption

[cheshirecat]

But presented a bit differently.

This using over 250 VFR800's
Think I get the midrange on the 750 or 300/340k per tank

Had a browse thru the site - it includes a heap of bikes (including DRZ400SM but not GS1200SS).

It looks like the fuel usage data is all converted to US mpg. As the US gallon is smaller (80%) of the proper (UK) gallon, the mpg figures look on the low side if one is thinking in proper mpg.

It looks like it converts currency though which is quite smart. So the $ per mile figures are comparable. Surprised by the wide spread within the same bike model though.

Interesting site. Thanks.

Quality of fuel will be a big factor, along with riding style (related to geography of location I'd imagine).

At the top left you can change units to L/100km or km/L.

Riding style is always far and away the most significant factor in fuel consumption. All the tuning and fuel-saving devices in the world put together have nowhere near the same effect as the right wrist or foot.

Same with laptimes in racing. Rider ability, (and some luck), will much more affect these than anything else.

I use Fuelly to track my fuel usage in my vehicles, it's quite handy, especially after doing some tuning to see if a change has resulted.

The marketing execs at Hero Honda deserve pay raises for the their model names...

Glamour (1)
Hunk (1)
Karizma (2)
Karizma R (3)
Karizma ZMR (2)
Passion (1)
Splendor (2)
Super Splendor (1) "

I can just imagine them in NZ.....
to wit: ".... have you noticed how much Barry enjoys riding his Honda Hunk these days? Since he upgraded from that Super Splendor POS he's a changed man..."

Above about 100kph most of the fuel any bike uses is pushing against air drag. (I assume the bike is fairly well tuned & has no more than an average fairing.) The horsepower required to sustain a speed above 100kph therefore becomes nearly proportional to the cube of the speed, but the rate of distance coverage is just proportional. Hence at 200 kph a bike should give about one quarter of the kpl it gives at 100kph. In practice this is not far wrong and is not greatly affected by cc rating etc. Sedan cars tend to be a bit more complicated because they normally have better aerodynamics in relation to other drag factors.
FYI ... sootie
PS: Using about 50% more fuel cruising on a given bike at 123km/hr than at 100km/hr might be safer to prove!

"Yes, he's full of Passion and positively oozing with Karizma these days..."

yep in aware of the basic principles of aero dynamics. I'm riding a 2 valve air cooled 650 single with no fairing and fitted with road legal knobblies that flex alarmingly over 140 km/h so its not likely to ever see 200 km. Its the well tuned aspect I'm using my fuel economy as one measurement to help me achieve as I've fitted a pipe, opened the airbox and fitted a different carb and im still sorting the jetting.

Someone suggested to me the other day that if you counted the fuel pump click rate you could correlate that with fuel consumtion while riding assuming each click was a constant volume. Still thinking about that. Of course the bike would have to have a fuel pump!
