Yep, the NC700 seems to be a very fuel-efficient engine.
For comparison, I filled up this morning, and saw that I had got my DL650-2012 to go 100kms on 4.1 liters of fuel.. but this was all "stop and go" city-riding, havenīt had time to leave the urban area at all lately, on more steady touring-type of riding I do expect it to go down to about 3.3-3.6 liters for 100 kms. And the bike currently has less than 2000kms on it, that could also affect consumption a tiny bit. Iīm using gasoline with 5% ethanol.
(...now anyone care to enlighten me, how does one convert these funny European figures to US MPG??)
