If you follow the forums you will find that no other subject seems to bring so many different opinions than that windscreens.
In my opinion we are all different sizes and have different riding positions so for a windscreen to be "all things to all people" it really needs to be completely adjustable in angle and height.
I have tried several including CHAD but find the Madstad system the best (and cheapest) by far.


As Mark says on his web site- www.robobrackets.com
" This is a complete drop-in system custom made for the Can-Am Spyder. The base is a black powder-coated aluminum adapter plate that replaces the stock windshield. A set of black RoboBrackets attaches to that metal plate and then a 20" windshield attaches to the brackets. With the windshield 'detached' from the fairing you now have control over the height, angle and depth of the shield. The results? Smooth airflow placed exactly where you want it. There's no longer a need to hide behind a gigantic fixed touring shield that robs you of mileage and spoils the open air motorcycling experience.
