Greetings and welcome to the versys. It will depend on your riding style, if you are real aggressive I don't think your mpg will be much different. If you ride at a more relaxed pace and keep the rpm's around 3500 to 4500 I think about a 4 to 6 mpg difference. I have the 44t rear sprocket and if I get aggresive and rev it hard on acceleration I get around 51 mpg, but when I ride at a more relaxed pace and stay in the 3500 to 4000 rev range I get 58 to 60 mpg. I also don't adjust my math for the gear change, meaning changeing to the 44 t will through off your odomiter slightly so when it shows you rode a 100 miles in reality its like 104 miles. Hope this is helpfull, I know there are smarter individuals than me on this sight that can give you better numbers like Invader, that guy is a wiz on stuff like this.
Those who say money can't buy happines haven't bought A VERSYS.
