Like Crager said, if you pull with the loops... They're only there for emergency purposes only and aren't designed for a steady pull. If you mounted the hitch properly with the included hardware (Grade 8 bolts) then you shouldn't have any towing problems. When you pull with the hitch, use the hitch ball as that's what it's for.

As for welding the hitch to the frame, Tone's model would require some modification as part of the fuel tank skid-plate is sandwiched in the installation. Also, for any frame welding you need to engage the services of a professional welder as the VX's frame is made from cold-rolled steel. Regular welding will severely weaken it, leading to sudden failure.

Grade 8 hardware used with backing plates and generous load spread will allow frame-mounted accessories such as the hitch to take a lot of abuse. But just bolting or welding things on without proper load design, also known as good ole common sense, is just asking for trouble with an engraved invitation.
