Ok so I have been riding my 05 XTX for a couple weeks now and have fulled up a few times when the fuel light comes on.

Commuting or open road I am hardly gentle but am still getting 155 - 160km before the fuel light comes on. So I diligently go and full up and find I am only putting in 8.2 - 8.5L of gas.

Economy wise this is damn good compared to the R1 but after a quick search it seems I have a 15L tank!!!! does that mean I still have roughly another 120km before I am seriously running on fumes??

Just wondering how far I can push the "fuel trip" length if I need to.

Had 134 miles to empty on my old 05

Good question and yes, there should be a total of 15L in the tank so that means generally 10L to reserve and then another 5L left. My reserve light usually comes on at about 190 km and I get about 9 to 10L in but note that I have never tried more than about 20km with the light on so dunno if it is really another 5L. Any other comments????

SOLD the XTX for a Super Ten 1200. And just bought a Raptor 700 so staying on here for some tips....

the reserve light seems a bit unreliable as to when it comes on sometimes i have done 25 mile on the reserve light but i remember one time i pulled up on a petrol station at 11 mile on reserve and ran out as i pulled on so nowadays i play by the rule light comes on i find myself some fuel

hmmm so it seems like my reserve light is coming on a little early then?
Can't find anything about adjusting the sensor electrically so might go through a couple more tanks and then look at where the sensor is positioned.

Based on my observation of my 05' X I consistently get 9.5 litres burnt before the reserve light and I tend to use at least another 3 before I fill up. On a couple of occasions I have seen 13.5 litres go in.
Based on my riding style and state of tune this kind of equals 190 km to reserve and 260 km before I want to fill up even allowing for a half litre of unburnable fuel at the bottom I think my bike would do 300 km if by my poor planning I had not filled up earlier.

A word on the reserve light.
When you are past 8 or 9 litres (or so) used and going up or down an incline for a period it can cause the sensor to trigger the reserve light, if you then hit the flat and the light goes out and you then run 5 km with out triggering the sensor again your F-TRIP on the dash will reset.
Likewise if you filled up and did not clear the F-TRIP as you ride down the road it will reset and revert to odometer after 5 km.

On my 2011 Tenere the reserve is huge. The manual has it at 6.7 litres (a whole UK gallon and a half!) which makes the main tank 16.3 (giving a combined total of 23 litres).

My experience is the gauge starts flashing at the right time � giving you potentially 100 miles of reserve. When I�ve filled it up shortly after it zero�d I only managed to get in 17 litres.
