1olbull,
I built two R3's up, pretty much twins, both had modified frame mounted Harley FXRT fairings, and both had those racks on the rear since we both ride solo.
I built the racks and mounted a Givi plate to each. The original "Blackie" I still ride:
After that trip my wife decided she wanted something lighter to ride, so like a fool I sold "BlackieII". Unfortunately only 3 weeks after the new owner had it he was in an accident and totaled it, Only one "Blackie" now.
