I went through this building a trailer hitch for one of my motorcycles. In my case, no one built a trailer hitch for that motorcycle. It ended up costing me about $160. About what a manufactured hitch costs for more popular bikes. (Mine tend to be on the quirky side.) On the positive note, the hitch worked perfectly. Outside of acceleration and breaking differences, you don't even notice the trailer, even in the twisties. Very stable.
