I got 48 kms (about 30 mi) with the fuel light on the first time my 1098 (with the same tank) ran out.
The second time I had only done 38 kms (about 24 mi) but I had stopped overnight and re-started that time.
That meant it had started up on the cold-running (richer) circuit, and got the lesser mileage.
And yes - the most I could get into the stock tank was 14.7L when it was bone empty - as opposed to the 15.5L claimed.
Since I fitted the ETI tank (about 35,000 kms ago) I haven't ever looked like running out.
