Just fitted Nippy Normans to my 1150GS. I'm 6'7, bike has Adventure screen and Tobinators. I can find a sweet spot but a but limited. Read good things about the wings so decided to fit them. It didn't take long but I recommend the use of a heat gun, the type used for decorating. Whole job done in under an hour, if you're careful you can even heat them on the bike to adjust or make them even. Haven't been on a ride long enough to comment on their effectiveness.
