This hitch fits BMW MOTORCYCLES ...all Airhead Models from 1970- 1995. R65, R60, R45, R75, R80, R90, R100.
It is set up for a receiver now but the receiver can be cut off and use as a "ball" hitch. I have a one wheel trailer that I pulled and it needed a receiver type hitch. $150 plus shipping. I would think that would not be cheap as it is long , odd shaped and heavy. Pick up for free in Menifee, Ca 92584
