I have run a 'Lip on two bikes.
On bike one, Suzuki GS500F, the Laminar Lip did not work for me. It did what it said it would but set up a tremendous roar. I was able to return it for a full refund as it was not used long enough to get damaged or scratched.
On bike two, NT700V, I tried another one largely because the company had been good to deal with. The Laminar Lip works well for me. It moves the air flow higher, over my helmet, allowing me to run the windshield low enough to look over, even in the rain.
