I'm using 6L/100kms on my 1000s. Most i have ever done is 240kms before refuelling. Haven't had to push it - yet! No city commuting tho. Fuel light rarely comes on. It's shy.
Shit, I wish H.
My 1000S gets the light on at around 180-190 (Commuting, but freeway and 80kph highway)
230k's and I'm pushing the thing !!
