Im going to venture to say its a bit different.. Puttys trailer is a dirtbike trailer. Based on the specs of the one posted for max hauling weight I would say that this one my be tailored a bit more for sportbikes. maybe not. The one thing to take into consideration is that if it is a DB trailer, you will want the middle ramp to be pretty far forward as you dont have much clearance when hauling 3 sport bikes due to their width.. they need to be secured extremely well or they will bounce into each other.. We would actually secure the outer bikes with them leaning slightly away from the center one. Trust me, I towed putty's trailer to the gap with it loaded to the hilt and mine in the bed of my truck on more then one occasion.
