The Windscreens for F800S & F800ST are small and sporty. So they don't give a good wind protection. Our Vario touring screen, has a spoiler at the top of the airfoil. The spoiler can be adjusted for height and angle in seven positions. The air current deflected behind the spoiler reduces the otherwise annoying turbulence. The Touring screen has the same shape like the F800S & F800ST's original screen, with an additional upwardly tilted airfoil over its entire width to deflect wind pressure away from the rider, ensuring an easy, relaxing ride, even on long trips. The V-Stream sets new standards in design, technology and comfort for the rider. The unique V-shape makes sure a brilliant aerodynamic and reduces the noise level. The screen is available in flat with 42 cm and in high with 49cm. A transparent and aerodynamic wind protection with a spoiler as air deflector and a black edge protection gives our High Windscreen. Compared to the F800S screen it is 17cm higher, and compared to the F800ST screen it is 7cm higher. Just as important as the optimal wind protection is the right maintenance of your windshield. Therefore, we offer you the National Cycle RainZip Rain Repellent and the National Cycle Shield Wash Windshield Cleaner. The RainZip Rain Repellent ensures a quick drainage of the rain water and reduces the annoying drop formation. The Windshield Cleaner removes the dirt of the windscreen gently but effectively with the delivered microfiber cloth.
