GSX-R1000 fuel economy - I'm impressed

**jrandom** · 8th November 2007, 09:28

I filled up the K2 yesterday after using up a tank around town, a bit of filtering through rush hour and a bit of time on the motorway, no open road riding.

268km on the trip meter, and it took 15.5L.

That's 17.3km/L, or 5.8L/100km.

Pretty impressive for a 140+hp machine. I must say, I expected far worse.

Of course, at less-moderate speeds on the usual closed private roads, that efficiency drops somewhat. But, still, it's nice to see that a 1000cc inline-four monster can be a reasonably efficient commuter if you treat it right.

thats far better than my 600.

lowest i get is about 6.4l/100kms
fuel light comes on around 200kms, average, have to really think about it 220-230kms

i lie looking back at some my milage reports i can get it down to 5.5l sorta thing but that is my communting to akl for work, so its 200kms sitting at 100-110 sorta thing.

normal around town is 6.5,

If you actually use your 140hp, you'll need more gas

Pretty impressive indeed... I get just about 22 km/L on my 45 hp 250cc

But of course.

I'm saying, it's impressive that Suzuki can make a 140hp engine that also works efficiently when you're only using a third of its ponies.

Just imagine what it'd do with me on it then

My 79 CB does something similar, trouble is that technology should be better than that, it doesn't really seemed to have improved that much in the last 30 years, but I think the focus has been on power rather than economy...

gas in = horses out.

i think, otherwise somebody would make a engine that ran on rubbish and creates foward movement in the form of dreams.

Wish I knew how much the Mille used but the friggin battery is shagged and the trip metre keeps reseting!

Incorrect.

Gas in = (horses out + waste heat + incompletely combusted hydrocarbons).

Getting the 'horses out' term of that equation as high as possible in relation to the other two across the entire range of an engine's operating conditions is the trick.
