It is a great bike in general. On fuelly, they range from 35 to 46 mpg between about 13 different bikes. Mine seems to be the highest average and also has the most fill ups. I ride year round and don't hot rod. Don't use hyper mile techniques either. Just ride for fun. As for fit, 6'3" isn't going to be enough to compare to others. If you want to know about fit from the saddle to the ground, you need to talk to folks with the same inseam. If you want to know about how the wind hits your upper body/head, then need to match someone that sits the same in the saddle. Easiest is to find someone your height with the same inseam. The tall windshield has 2 ducts at the bottom that helps eliminate buffeting. On the CTX forum, the most ( not all) have found the helmet to be the worst culprit for buffeting. Go join the forum, use the search function, then ask more specific questions. They are a very helpful group and not the type that try to butter you up so you buy it. If they think it won't fit you, they tell you point blank. When you buy it (or don't) still come back here and let us know what you decided and why.
