ZTechnik┬« revolutionizes windscreen performance! The advanced 'V' shape and dimensional contours push the wind vortex out and away from the rider's helmet, resulting in a peaceful, quiet environment. This improvement is notable for the passenger as well.
VStream windshields are made from tough FMR hardcoated polycarbonate. This high-quality material, along with state-of-the-art manufacturing techniques, provides these windscreens with outstanding clarity and strength characteristics unmatched by any windscreen maker worldwide. Optically, the VStream windscreen is clear with virtually no distortion (unlike the hallucinogenic views you get from the stock screen).
VStream Windscreens are 30X more scratch resistant and have 20X greater crack and impact resistance than other aftermarket windscreens on the market made from commonly used acrylic or "aircraft plastic".
Also reffered to as windshield, windscreen, shield, screen.
4.5mm FMR hardcoated polycarbonate.
The windscreens only fit in combination with the original BMW LED indicator lights or with the longer original BMW indicator lights with bulb (version USA / Canada). If you have installed the small BMW Sports windshield (e.g. on the white R1200R LC with the red frame), you have to remove it.
The back side of the speedometer aluminium mount/bracket can for example be covered by BMW part no. 46638392893 288. However, this is just an optics and taste issue, the windshields are black at the front at this point, so that you have no direct view of the speedometer's back side.
You can see the corresponding pictures in the installation instruction at the bottom of page 3.
