I would have gone with the naked one too. As far as having to rev and sproket size I would just get the bike broke in good along with some decent tires on it then determin if you need to change the sproket. On smaller bikes some will not reach top speed with a stock sproket and the bike with the 46 tooth might be a tad faster with the higher rpms from the different ratio. Way too many people get concerned with gas mileage on bikes. The difference between 60 and 70mpg isn't going to be more than a buck in a weeks worth of riding and maybe even a lot less.
