Made here in the USA, Zero Gravity's(®) new lineup of 2011 Kawasaki ZX-10R windscreens is now available in four distinctive shapes. The SR Series™ (20-263), which approximates the size and shape of the OEM windscreen, adds flare to the bike's look in Smoke or additional clarity over stock when ordered in clear. The Double Bubble(®) (16-263) is Zero Gravity's version of the now popular "stepped profile" design pioneered by Zero Gravity Racing in the mid-90's. Sculpted to the ZX-10R's distinctive race lines, the Zero Gravity Double Bubble enhances the bike's race look while providing added aerodynamics. The "Corsa Series™" screen (24-263), shaped to emulate the factory race bikes campaigned on the World Superbike circuit, is approximately 1.25" (31.75mm) taller than OEM screen providing additional wind protection while tucked in at speed. Last, our tallest shield, the Sport Touring Series (23-263), which is 1.5" (38.1mm) taller than stock, provides additional wind protection for street or touring applications.
