My bike is a 2003 and they have a 4.4 gal capacity, I usually hit reserve at about 145 -150 miles. If I go a lot of highway or open country cruising I don't hit reserve until about 165 miles. The carbed bikes have a lot of variance it seems in mpgs because a lot of us use different jets, needles, etc. The new models are fuel injected and also have a 5.1 gallon tank. You should try to schedule a test ride or hit a demo day. And if $8,000 is a bit steep these bikes used go for about half of that and there are some low mileage deals out there if you look.
