My C14 is an 08 and does not have eco mode. On my last trip of 4K miles, the light would come on around 170 or less assuming I had the nerve to wait that long. Most of my trips are out west and the 30 miles or so remaining after the light might not get you to the next station. A lot of the time I was alone and didn't feel like risking it. My buddy with a BMW 1200 GS was getting the same mpg, he just has a lot bigger tank. I believe the eco mode came about due to complaints on range with the 1st gen. The C14 is an awesome bike and I will probably be riding it for years to come. There were just some qualities of the C10 that really fit my long distance riding style. I even got my bun burner gold on it
