Don't know if that info is available yet. Haven't found it even on the Honda Japan web site. I did find out that the max load weight limit on the ST1300 is 410 lbs for rider-passenger-luggage. I suspect the CTX1300 would be at least that given a steel frame vs. aluminum frame on the ST. I've seen the frame on the world Honda web site and it seems fairly substantial for the rear sub-frame where the rider/passenger/luggage would be supported. The GW gl1500 is higher and I know of one guy around here who used to ride one who actually weighed more than that limit. He went through a few GWs in as many years from broken frames. He was WAY over the limit and I was surprised he was even able to climb on one. I also know of many GW riders and a few ST riders who regularly carry more weight than the limits for those bikes with rider/passenger/luggage all added up with no issues... that then know of.
