I was looking to buy one for the s4r but I couldn't find one that had some ventilation, visibility and kept the structural integrity. Form and function.
Actually, two out of three. Original function was to provide total environmental closure; the screens are open to the environment.
But, consider this nit pick is coming from someone who runs SpeedyMoto Leggeros which are mucho more open to the environment.
Nice job! I will be very surprised if your design is not copied.
BTW, what type of paint is that on the belt edges? They are painted, right?
