Ok, new to this bike and have only taken it for 6 putts but I really like how the bike handles in sport mode. It rides much more like I'm used to, with a better power band in all the gears. So I'm riding around in drive mode and feeling a bit bummed about my new ride, but I ride on some more and as usual, after more riding, I get some clarity. I realize that I have two options on my new ride. I can enjoy the power bands in sport or enjoy the better MPG in drive mode. So now I'm enjoying the luxury of both modes, tho sport is still my favorite.
