· FORUM GODFATHER.....R.I.P. PAT
The spec says the GVWR is 965lb and the curb weight is 525lb so the capacity for adding weight is 440lb. That being said, it's really a legal fiction. There are many variables to what is safe. The surface, speed, rider experience, suspension/tire changes and even aerodynamics and placement of the load all change how well the bike handles a load.
