I just bought an 08 GSA and was told by the previous owner that the BMW Side Luggage is not water tight and that this was common with all the luggage. Is this right? My last BMW had Jesse Luggage and I don't remember it letting any water in, but then again I don't think I ever rode through any rain storms either. If this is the way it is what do you use for Dry bags for the side and top cases that fit the bags. Thanks. Pic of my bike in my garage..
