Yeah, consider what Nelso says. He's on the money. I have a ZRX and have ridden a couple of CB1300's. They are slower steering, heavier, more top heavy, worse suspension, won't hold as tight a line, don't have as much ground clearance, ride position is not as comfy nor as good when "pressing on", brakes are no different seat is more comfy on the Honda, but a Mr. Wog's or a Sergeant fixes that. They also don't have the engine that the Kawasaki has. Sure, bottom end and midrange is similiar, but the ZRX keeps on boiling when the CB has signed off and is begging you for another gear.
Personally, I would just go find a good 2nd hand ZRX and go enjoy it. Mines got 80,000 klms on it and Is staying in my shed forever.

(Fuck... actually, that last comment is ironically true.... it has sat in my shed all year this year....
