I don't really have direct answers for your questions but our bike (GSX-s1000), at least in North America, isn't really popular. So aftermarket is going to be a little difficult unfortunately. Coincidently, I have an order in with you guys for a windscreen right now. I ordered Aug 20 and am still waiting patiently. I realize that the product I ordered is basically a one of a kind, as I have not seen another one in the style/color. Would I have liked to have it by now, of course. But you guys were honest with me from the start in letting me know there was going to some waiting involved.
I believe some of the difficulty has to do with the companies that make products for our Hondas, Yamahas, Suzukis etc are European based. ie, Ermax, Pyrimid Plastics, Hepco, Puig etc. So, its a guessing game what to keep in stock. All of this is obvious I'm sure. So customer service is key in this difficult business model. Just my 2cents.....
