The V-Stream Windshield
ZTechnik revolutionizes windscreen performance
with its new VStream® windshield. While creating
a comfortable ride for the BMW sport touring
rider, ZTechnik introduced QUIET into the equation.
To create COMFORT, other manufacturers
will offer taller windshields and spoiler tops to lift
the air stream. ZTechnik designed, for the first
time ever, a windshield with airflow calculated
and adjusted to quiet the rider’s environment. In
addition, VStream windshields are designed with
an unprecedented area of protection and an outstanding
level of DURABILITY and OPTICAL
CLARITY that is only available through the use of
Quantum™ coated Lexan® polycarbonate.
QUIET
The typical airflow pattern of the wake from most
windshields is called a van Karman vortex. At
speeds of 50-90 mph, the air swirls off the windshield
in an approximate 90-degree segment of
rotation, i.e. it rolls off the windshield, hits the
bottom of the rider’s neck on the way up, and
curves off the shoulder at approximately 45
degrees. ZTechnik gave the VStream its name for
the shape it takes at the upper edge. The “V”
shape is so outstandingly quiet because it pushes
this vortex out and away more than 4 inches
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.
COMFORT
The advanced, patent pending “V” profile and
three-dimensional contours of all VStream windshields
create a calm and quiet air pocket for the
rider. This improvement is notable for the passenger
as well. Every aspect of finishing a shield will
contribute to the comfort level. That’s why ZTechnik windshields have smooth radiused edges on 4.5mm-6.0mm thick material. These features and more make V-Stream the most comfortable windshield you can ride behind on a sport-touring BMW® motorcycle.
DURABILITY and OPTICAL CLARITY
Thick Lexan® polycarbonate with our exclusive Quantum™ hardcoating – nothing
can beat it... not even a hammer! See the next feature to learn why.
We manufacture our windshields from thick
polycarbonate material. There is simply nothing that stands up to its strength and durability. Compared
to standard acrylic windshields, polycarbonate is 20X more impact resistant and 23X more crack
resistant. That’s performance you can feel comfortable riding behind!
When our exclusive Quantum™ hardcoating is added, you get an unbeatable combination. This special
hardcoating is a quantum leap beyond regular FMR hardcoated polycarbonate (it’s 10X more abrasion
resistant) and it’s light years beyond standard acrylic windshields (30X more abrasion resistant)!
What does this mean to you? Think about
riding into the sun or at night and not having
to look through the glare of fine scratches
that eventually show up on your screens.
Quantum coating gives your windshield
much better optical clarity and scratch
resistance, and your windshield will stay
that way a lot longer. The longer you ride
and the longer you own your Quantum coated
windshield, the more you will appreciate
this new coating.
