Good looking bolt-on brackets are simple to make and theres are no change of damaging the ROPS. Besides with brackets, they are movable, removable and adjustable. Gives you a chance to be creative.
That's more or less what I did, works great. Some folks get antsy about welding on your ROPS, but you'd have to be pretty bad to damage the one on a Kioti, it's a very heavy wall tubing.
