GL1800 Laminar Lip

This is a Laminar Lip. This clear acrylic panel is designed attach to the top of the stock factory windshield to reduce the amount of wind turbulence behind the windshield. This is made for the riders who like to look over their windshield. If you have your windshield set to look through it, then you don't need a LIP. And since this will actually be a second layer that you would be looking through, we don't recommend this because of the extra distortion. However, if you look over the top of the windshield, then a LIP will make your riding more pleasant. It attaches easily with high strength 3M Dual Lock fasteners. This will fit the stock windshield on all 2001-2017 Goldwing GL1800's.

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.

The LIP is an inverted airfoil located above the top edge of the windshield, attached to the front of the shield. As air flows between the windshield and the LIP, it follows the underside airfoil of the LIP and is redirected more vertically. This air eddy then diffuses the oncoming air, in effect, to raise the blast of this oncoming airflow. The end result is that there seem to be three different air speed zones as you ride along at a set speed:

1. Behind the windshield - very little wind speed
2. Above the windshield for 6 to 8 inches or more - a wind pressure well reduced from actual speed
3. Above this height the blast that was at windshield height before the LIP was installed

Another feature of the inverted airfoil is that it increases down pressure on the front wheel. As a motorcycle proceeds down the road, air pressure (effectively from the front-- although the air really is not moving, the bike is) tends to rotate the motorcycle around its roll center lifting the front wheel and loading the rear. The LIP opposes this action to some degree.

The LIP does all this without your having to add a larger windshield. In many cases it works better than the taller replacement accessory windshields, because although they may be taller, they do nothing to control airflow.
