I have heard several opinions on this subject.  My Danson rig adds 200 lbs to the weight of my Burg 650.  Does the weight that my trike can handle as far as rider(s) and gear increase, decrease, or stay the same? I understand that some or all of the weight increase is handled by the rear outrigger wheels.  What is the weakest link in the weight capacity formula?  The bike frame?  Powertrain? 

I weight 330 alone, so this is of concern if I wanted to take a corider.  Thoughts please?
