Laminar

We used to say if you ride a Goldwing or some other motorcycle that requires you to look through the windshield then you don't need a LIP. If you ride a fairing-equipped bike and you look over the top of the windshield, then perhaps a LIP would make your riding more pleasant. We have found that even riders that look through the windshields and their passengers can have a more pleasant ride with a LIP.

The design of some fairings allows the wind to flow around one side then the other creating buffeting at the rider's helmet. LIPs are designed to trap the air from flowing around the sides of the windshield and redirect it to flow over the top, lessening or eliminating this buffeting.
