Yesterday was my first long ride with a new silver top case for the 2007 Norge I scored off wildguzzi classifieds. A PA dealer found old/new stock in a box.
They must have used the wind tunnel in design because it works great. No buffeting. None of the dreaded back wind pressure pushing the back of my head forward like on my BMW, even at 90 mph. And it looks great (for a top case.)
An aside, rode Lake Davis loop first time this year and it brought involuntary grins.
