|Windscreens for BMW R1100RS
You have probably heard it if you have spent any amount of time aboard
a faired motorcycle. It may be better or worse depending on the motorcycle.
It may be quieter or louder depending on your height. It may be very annoying
for some riders, and not at all for others. But it is always there. At
its best, it sounds like the gentle flap-flap-flapping sound of a hankerchief
fluttering in the late afternoon breeze, sending off loved ones aboard
the Titanic. At its worst, it sounds like the angry FLAP-FLAP-FLAPPING
of bed linen on a clothesline as Hurricane Gloria is rolling in. (Oh, you
think that's bad writing? Read this!)
"It" of course is turbulence.
I don't like wind noise. On long rides it makes me more tired. On race
tracks it distracts me. And over time, it will reduce my hearing acuity
to the point where I can't tell
Lola Run from Segovia.
This is a summary of my ongoing search for the perfect windscreen for my
motorcycle, a 1994 BMW R1100RS.
The stock wind screen has a small flip
up at the top. This is probably BMW's compromise to provide more wind
protection without increasing the size of the windscreen. Unfortunately
it also makes for very turbulent air coming off the top of the windscreen.
At my height (5'6") and with the adjustable seat in the middle position,
this turbulence is right at ear level. I can tuck in a bunch, or I can
stand up on the pegs a little to reduce the noise level. Neither of these
is a long term solution.
||My first attempt was the low budget approach. I used masking
tape and a marker pen to mark a line on the windscreen where the curvature
changes from concave to convex. Then I used a coping saw to cut off the
flip up part. The airflow is much smoother. However, wind protection is
also greatly reduced. This is actually good in the summertime, but not
so good when fall rolls around.
||Next I bought an Aeroflow screen from San Jose BMW. This
screen also has a flip up at the top, but it is also significantly taller
and wider than the stock screen. Wind protection is much more, wind noise
slightly less. Overall, this is an improvement compared to both incarnations
of the stock screen, but not it is not perfect. From some angles, this
flat-ish screen looks like a tombstone. Probably OK for a Harley, but slightly
odd on a BMW.
13,000 Mile Update
||My current screen is a Wudo from Cascade BMW. This screen
resembles a classic racing bubble, being curved front to back as well as
side to side. I happen to like this shape best. It also creates the least
turbulence of the four screens I have tried. And it has a bit more coverage
than the stock BMW screen. On the downside, the mounting holes took some
fiddling to line up. The easiest way was to raise windscreen height adjustment
before installing it. As of this writing (21 August 2000) I have had this
screen for a year and 5000 miles, and I still like it.
The Wudo is a keeper! The screen has held up well. Not
many scratches -- and I'm not particularly good about taking care of it.
I have never raised the screen adjustment above its lowest setting.
With fresh ear plugs on, the ride is about as serene as anything short
of a Buick. Here's some more
