Rode a 189 miles on a single tank of gas and didn't run out. Was shocked. Of course I keep the revs between 4,000 and 4,500. Don't think I have ever ridden that far and not let the GRiSO gallop a tad harder! Was an adventure wondering when I would run out. Of course I had a gallon strapped on the rack. Was impressed it went that far. Still had .3 gal left in tank!
