WINDSHIELD HEIGHT: How to choose your height/width
1. If you have a stock , non-adjustable windshield, go to step #2. If your stock shield is mechanically adjustable, lower it to the bottom or lowest position. If your windshield is electrically adjustable (RT, LT, FJR, Connie 14) extend it about a quarter (25%) of the way up.
2. Get a measuring tape, straight edge, or two yardsticks.
3. Move your bike to a level spot.
4. Tape the yardstick to the center of the windshield using masking tape.
5. Sit on your bike in a normal riding position. From between your chin and no higher than your mouth use a straight edge or additional yardstick pointing towards the shield. Measure in a level line parallel with the ground to the yardstick taped on the shield. As an example if the straight edge from your chin to the taped yardstick on the shield measures about three inches above the top of the shield and it’s level, you would be best suited by a +3” taller shield. Simply put the top of the shield should be even with or just below your mouth. You can do this yourself but having an extra set of eyes is very helpful. Width is dependant on your body type, more robust riders will want more width for better torso protection, while a smaller rider may find that the stock shield works perfect. This is general rule of thumb and is effective for the majority of riders & bikes.
