Fastest "production" touring bike...that would actually be the Gold Wing I am sad to say. I love the R3T and it is as fast as I need a bike to be but the Gold Wing is pretty hard to beat with that 4 spkr stereo, cruise control, heated seats and grips, trunk and don't forget the reverse gear (very handy in a 800+lb bike). Horse power GW=119 HP versus R3T = 107 HP but the R3T does overwhelm the Gold Wing in torque...GW=125 ft/lbs versus R3T= 154 ft/lbs (if I remember right). In an ideal world...I would have both.
