How many KM's should you get out of a tank of fuel on a GPX?

Update on 600rr economy...

On a run, kal to perth, i managed about 5L/100km.


Sitting on 130-140 ish....

Figure on 6L/100km and you should be pretty safe methinks.

I got 409km before using reserve when I was still breaking my bike in. Now I get about 360km on average and thats riding it hard on the throttle. My Gpx is two years old.I commute between Bullsbrook and Malaga with not very many stop/starts on my journey.

I've gotten quite a bit over 400 out of my GPX tank, round about 420. That's using BP ultimate and driving it hard.


Heres a few thoughts on the largely different numbers which people have given. Aside from driving technique / bike condition etc. One major contributor to how far you will go from a tank is obvioulsy, how full you fill the tank.

I generally fill it, and by fill it I mean put in another 2 or 3L beyond the point where it looks absolutely full. To the point where its about 20ml off overflowing.
Its amazing how much more will go well after the nosel has auto shut off and still well after the petrol level seems full.

If there is a 2 or 3 L on variance on how "full" some of us fill our GPX's, maybe that explains some of the difference in KM's per tank.

Just fill up when you reach 300kms.

Still on my L's so obviously taking it easy but checked it yesterday and am getting 22km/l so theoretically that is 396km's from a full tank (incl reserve).

Be VERY careful doing this - very, very careful. Look in your manual. I generally only do this if I'm about to go for a long ride, at least another 100 km, by which time I've used up the extra 2-3 L I put in.

The reason you can still put fuel in after you've reached the neck of the fuel tank is because there's an air gap built into the tank. This air gap is designed to allow for the fuel expanding or contracting when you either leave the bike in the sun or it gets cold at night - basically when you're not using your fuel tank. Filling this gap can result in loss of structural strength, the tank collapsing or expanding beyond the limits it was designed for, so on and so forth. Basically you will weaken your tank by doing this.

Great point Tenchi, taken into consideration.
