Seems more like an algorithm-generated bot site to me. A human being selling motorcycle parts would hopefully realize that the TW has a single shock and doesn't need to choose from one of many "shock sets"
I might be wrong, but nonetheless I wouldn't personally trust the "folks" over at partsnmore.com with my credit card information. I guess you could call them to feel them out, but oh wait! The only contact information they provide is email addresses @partsnmore.com!
Something tells me that the "more" in their company name might just be credit card fraud and identity theft. I wouldn't hold out a whole lot of hope for the "parts" aspect of their business model myself.
