17/40 gearing on TT250

Well since I can't leave anything alone and my riding is entirely on the pavement I decided to install a 40 tooth rear sprocket and I am actually pretty happy with the results. While it doesn't like the wind much on the top end when the wind isn't a factor it performs really well especially in city driving. Last night I took it on the freeway and without the headwind and in traffic it actually hit 73 mph at about 7300 rpm and was able to maintain 66-68 mph when I was alone in the gusty conditions which I think is pretty good since I weigh 250 lbs.
