My 1299S has now 4800 Km
I drove a 3200km long distance trip from south Germany to Austria Italy France and back
Very seldom i go over 6000rpm - my normal range is 2500 to 4500
The consuption is at 0,11l/1000Km
Seldom go over 6,000 rpm ... you don't know what you are missing out on! Go on, try it
My 1299s - had to top up with the recommended Shell oil a few times before its first service at 600miles and again a bit after. Got through 1/2 a bottle now and have 900 miles on the odo.
I suspect other litre sports bikes are similar.
