To be honest I haven't done many miles with it yet though it does seem to do the job, certainly better than the original, I'm 6'2" so buffeting was a bit of an issue. I'm just planning a trip to the Ardennes so will give it a good test then.
Here's a picture including one of the panniers. I have also fitted a Corbin seat (brilliant) a Puig touring screen, heated grips (Oxford) and a Kaoko cruise control.
