they tuned the FZ6R a little different than the FZ6 from what i read in MOTORCYCLIST. they gave a more broad power range with better response in the mid RPMs. basically perfect for regular city and spirited twisty riding. not so much for track, but thats not what this bike is made for. it always seems like bikes in this category are just old engines from the sportbikes and a new frame to make more money in a different segment. what i read is that yamaha actually put a bit more thought into this model and made it more suitable for the user group they are aiming for. i hope this is more truth than marketing hype.
