I am trying to remember parallel twins in Honda's past. I remember the 125, 160, 250, 305, 400 450, 500. The TM400 and 450 engines looked very much alike. The 70's 250 and 305 looked pretty much alike.Does anyone think that Honda's success with the CTX models will open the door to a larger CTX motorcycle in the lineup? Perhaps a CTX1300.
