The Zero Gravity Double Bubble windscreen offers better protection than the stock. The Duke and Mike windscreens are a bit too much like the clear “barn door” style I have seen on most cruisers for my tastes. I have no doubt that the Duke and Mike windscreens would provide very good wind protection, likely better than the Zero Gravity Double Bubble and vastly superior to the stock windscreen. The Double Bubble does provide a nice air capsule but not a “Wing” or “Connie” sized capsule.
The top of the "air capsule" seems to hit about the shoulders/upper chest at highway speeds on my 5' 10" frame. It is comfortable to me but then I am an avid road cyclist and during cycling season I ride a road bicycle about 15 to 25 miles a day, much of that in a tuck. I do not have an aversion to tucking on the Ninjette because that position is not alien to me. I tend to do a partial tuck at or close to 70 MPH to give the bike as little frontal area as possible in order to help fuel mileage.
The Zero Gravity Double Bubble offers me what I feel is a good compromise. I can tuck to increase fuel mileage and effectively punch though the stiff Texas winds. Additionally, I can also sit in a more upright and relaxed position and have enough wind protection that I do not feel as if I am going to be blown off the motorcycle. The Zero Gravity Double Bubble smoothes the air flow around the rider but still allows you to feel as if you are on a sport bike.

I had ridden over 5,000 miles with the stock windscreen on the Ninjette II before Zero Gravity introduced it's line of aftermarket windscreens for the 2008+ Ninja 250Rs. The "stocker" was pleasant to ride behind with the air capsule striking me about shoulder level leaving the helmet fully in the wind with minimal turbulence. I did note that with the stock windscreen I would often return from a ride with quite a lot of "bug splat" actually on the tank (a very rare occurrence on the 2005) indicating a sizable amount of air was being deflected into my body and down, not over my back.
The Double Bubble for the 2008s and above provides a slight expansion of the "air capsule" that seems to hit about the bottom of a full face helmet on my 5' 10" frame at highway speeds. The Double Bubble is therefore slightly noisier but provides more protection and provides easier tucking than the stock screen. The slightly taller air capsule appears to have just as tight and smooth an upper boundary as the air capsule formed by the stock screen. Preliminary statistics indicate a slight improvement in fuel mileage when tucked.
The Sport Touring series for the newer 250Rs throws the "air capsule" well over the shoulders and down the back. It is no noisier than the Double Bubble and provides greater wind protection for the upper body. Tucking behind the Sport Touring is the quietest of the group. It should be noted that one tends to spend a lot of time looking through the Sport Touring windscreen and not over particularly while riding tucked, therefore the dark smoke color is not recommended. The increased wind protection is an asset during winter riding. The Sport Touring would also be a good choice for touring with luggage or daily commuting.
During the Summer months I prefer the Zero Gravity Stock Replacement windscreen due to increased airflow. The Sport Touring windscreen gets the nod during the winter months due to the increased wind protection.
