blackjuju, what do you have for a front Sprocket? I am running an 18-43 and ride with my brother frequently, sporty 1200C, and we ride 2 lanes,( too fast) and freeways, maybe a little over speedlimit, and I have no trouble riding with him. That is a freeway gearing, not a rocket off the line, but dropped a 1000 RPM from the previous set up on a supersport.
