Getting back where this thread was going before the "manly" talk started....
I put a Slip stream spitfire S-06,smoked,on my 550,I was riding a BMW r80rt,and got used to the protection,the Spitfire is fairly small and keeps alot of the wind off my chest,blows most of the bugs up over my head and I get no helmet buffeting
I put a small stainless bracket on the headlight bucket to anchor the lower part of the windshield,it took a few minutes to align everything ,but I do not remove the windshield at all
