Plan to replace my noisy windshield on my 09 K1300GT and need some input from the guys who've replaced theirs. Who makes the quietest - least turbulence - windshields? Thanks in advance for your input.

See post #4 in this thread for a pretty complete description of the aftermarket windshields available for the Slant/4 GTs.

In my opinion...Aeroflow.

I have owned and tried BMW tall, Calsci tall, and Aeroflow tall. Aeroflow definitely is the quietest and do not have to look thru windshield. I'm 6'1", with a 32" inseam. Calsi tall quiet only if fully raised and looking thru windshield. If dash plate removed, then might be quieter. BMW tall is very noisy at any setting.

Greetings,
Although my moped is grounded due to icy road conditions , I drove the normal height Calsci windshield for a week or so.
When up the turbulence is mostly gone, it is that good that I do not use earplugs anymore.

It is not perfect but I did not want to put on a huge windshield as the aeroflow which might be perfect for the noise but a little tricky at higher speeds.

Do not think that the beamer engineers skipped the wind tunnel testing, I'm sure that their requirements for aerodynamics needed to match good behavior at top speed !!
That is why I opted for the Calsci, With the aeroflow I would be afraid of having the shield in my face when redlining the bike

I've ridden full tanks of fuel at triple-digit speeds, and maxed out the GT many times. The AeroFlow handled it just fine . . .
