I guess it depends on how hard you are going to ride. Its Texas so there arent any hills or curves. I get about 120 miles to a tank with my 06 if I keep it under 10k rpms and under 100 mph on the highway. I dont like to run my tank down to low even riding in normal conditions. Ive only had my low fuel light on once when I purchased the bike just to get an idea how far it would go. Play it safe and keep it topped off is my opinion.
