Towing a 7x12 trailer hauling Goldwing

I have towed my motorcycles all over on a home built single axle trailer without brakes and never had an issue. Initially we got it used and after a time made some upgrades. Had a spring hanger break in Louisiana got to shreveport and took to a shop where the guy was actually a blacksmith. He redid the hangers and never had another problem. Also added some shocks to control axle jump. I ran car tires and they held up well, just dont let them get too old. Your gw is only 900 lbs so if you get too much trailer/springs you will not have enough weight to actually load the springs and it will bounce on ya. Just like trailer pulled behind mc's. Some have 2 leafs and they bounce as they are set up for more weight than is carried. I took 1 leaf out of mine and it was much better. Most trailers do not require brakes until they have a gw of 3000lbs in most states, some may be 1500 but all depends on where it is licensed. Just some thought to consider
