I have one mounted. I bought it through Ebay. It ws on an 87 Goldwing so I had to contact the manufacturer (Champion) to get the bike-side mounts - $675 plus shipping, oops they forgot the steering damper, that will be another $35 plus $25 for shipping and I still had to beg for installation instructions. But hey - it only took 7 months to get everything from them. Great sidecar - too bad Champion doesn't offer customer service.
