About 3 years ago a lower rear rack was made and sold by Beaudry BMW in Idaho. It mounted behind the rear tire and extended out about a foot. I have one. The mounting system was crap! and the welds broke in about a month. I've since mounted the rack portion to a trailer hitch..works great.
I'd like to find another one (rack pieces..not mount). Does anyone have one that they would like to sell?- Thanks
