David, the TrailTech runs about $120 and honestly it was an eye opener to be able to see exactly how fast I was going and mileage I was getting with different gas from different areas of the country. In CO and UT I made better than 60 miles per gallon but in Nevada and AZ it dropped to just above 45mpg. I'd call that a significant difference based on how much ethanol was blended into the fuel. You might just be trail riding in the CO mountains but if you've only got a stock 2.5Gal tank, if set up properly, at best you'll get 120 miles before you go on reserve. At worse you'll run out of gas before getting back to the station and pushing a 240lbs bike up any hill in CO just plain sucks ass.
Just my .10 cents. Later Travis
