I saw a nice selection of official BMW Motorrad bags on the UK Store, U.S. site should also have them listed. I always try to go for the official stuff first before aftermarket, kind of cool having it all matching...looking like it just rode right out of a catalog 
Any idea of what size bag (in liters) you're looking for, or what you plan to carry?
Seen a 55 liter.
