BMW G650GS Sertao Windscreen VStream Touring Windshield Ztechnik Z2471

The new windshields are available in three different heights and tints. The additional wind protection provided by the VStream calls for a strong mounting system. The tubular frame provided ensures stability and offers an additional mounting point for ZTechnik’s Z6010 Accessory Mount.

VStream windscreens are made from tough 4.5mm FMR hardcoated polycarbonate. This high quality material, along with state-of-the-art manufacturing techniques, provides these windscreens’ outstanding clarity and strength characteristics unmatched by any windscreen maker worldwide. They 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”.

National cycle V Stream benefits:
VStream® — Experience the Aeroacoustic Difference

National Cycle's VStream® is revolutionizing motorcycle windscreen performance! While other manufacturers offer taller screens or air spoiler tops, National Cycle designed, for the first time ever, a windscreen with airflow calculated and adjusted toquiet and comfort the rider's environment.

PERFORMANCE
The typical airflow pattern of the wake from most windscreens is called a van Karman vortex. At speeds of 50-90 mph, the air swirls off the windscreen in an approximate 90-degree segment of rotation, hits the bottom of the rider's neck on the way up, and curves off the shoulder at approximately 45 degrees.

We gave the VStream its name for the shape it takes at the upper edge. The patented “V” shape is so quiet because it pushes this vortex out and away from the side of the rider's head. The rider’s helmet then resides in still air, and the passenger's environment is greatly improved as well. Of course, with small sporty screens of different sizes, the effect on the rider will vary, but there is always a notable difference in quietness and comfort!

Experience the VStream windscreens at a dealer near you and see why they are the most comfortable windscreen you can ride behind.

STRENGTH
VStream windscreens deliver unprecedented durability and optical clarity through the use of 4.5-6.0mm thick Lexan® polycarbonate with FMR hardcoating or our exclusive Quantum™ hardcoating.

What are the Benefits of Hardcoated Polycarbonate?
Outstanding impact strength! Nothing else comes close to matching the impact strength of polycarbonate, making it the ideal material for motorcycle windscreens. It is 10X stronger than H.I.A. and 20X more impact resistant than acrylic plastic (Lucite®). Real world testimonials, like the one from a customer who met a ball peen hammer at 75MPH attest to the outstanding impact strength of polycarbonate.
