I think you are saying how can a 1300cc bike have only 120horses, where a 1000cc GSXR has 170hp. I bought a CB1300 yesterday and all I can say is it´s all about Torque(GRUNT). For example I was doing 120km/h along the freeway in 5th gear, dropped back to 4th, gunned the throttle and the front wheel popped up for 2 seconds then I was doing 160km/h. This bike has power anywhere on the rev range in any gear....IT´LL ABOUT TORQUE MATE.
