Ztechnik Vstream Windshield

My new to me K130GT has a Ztechnic Vstream windshield. I like it but it doesn't provide enough buffeting protection for my copilot. Got to keep her happy so I am thinking about trying the Aeroflow windshield with the laminar plate. Rather pricey at $400 but gotta keep the wife happy. First I have to sell the Vstream windshiild... Excellent condition. No scratches. A description of the windshield is on this website... National Cycle: Products: My Order. Price new is $239.95 plus shipping, I will sell mine for $175.00 and I will pay shipping to anywhere in the lower United States. Send PM if interested,

Re: Ztechnik Vstream Windshield

Just a quick note to say how much I like the Aeroflow windscreen. I also have the Aerogards that attach to the side.

I live near Aeroflow, so I got to try both the standard and tall Aeroflow screen before deciding. I am 5'10" and prefer the tall screen. When fully up, I need to sit straight to see over it, but it is still comfortable. Generally, when fully up, I still have 1/2 inch to go. It works perfectly for me.

With the Aeroflow shield and Aerogards, there is a very still pocket/bubble of air behind the windscreen indeed. There is no noise at all, other than engine noise.

Issues:
* Your fuel economy will drop a little with the Aeroflow screen and Aerogards. Mine dropped by about 2 mpg.

* In serious humid summer heat, you will find yourself wanting a little more air flow. Living in Southern California, I switch out the Aeroflow shields and Aerogards, and put the stock BMW shield back. In the winter, I put the Aeroflow shield and Aerogards on, and enjoy them very much.

I have ridden with the Aeroflow shield and Aerogards in 22 F dry weather, no problem. They made all the difference.

Re: Ztechnik Vstream Windshield

Given the aggressive (for BMW) design of the K1300GT and the seat height difference between rider and co-pilot it would seem that you will always experience some buffeting and certainly more than on a touring bike.

The Vstream is a fairly large shield when compared to stock and is likely already putting strain on the shield struts, will the Aeroflow increase the stress or decrease?

Maybe you are riding the wrong bike for your co-pilot's expectations. Please post your findings once you have made the change.

Re: Ztechnik Vstream Windshield

Al,

I may be interested in the V-Stream. I'll have to ride over and check it out. I have a stock shield that is rather nasty to look through.

I owned an LT for several years and currently have a GTL with a Cee Baileys wide windshield and Aerowings, so I don't think my co-pilot has expectations that there is a windshield that will make the K13GT comparable to those bikes when it comes to buffeting. From reports I have read on the Aeroflow windshield I am hopeful it will reduce the buffeting some.

Re: Ztechnik Vstream Windshield

As I said in my earlier post, I hope you report your results with the Aeroflow. I have a good riding buddy that purchased a K1300GT and his co-pilot has expressed similar concerns. Like you he is currently using a Vstream that is not doing an adequate job.

Although the K1300GT has a passenger pillion the bike never seemed to me to really offer a positive two up riding experience (few bikes really do).

Re: Ztechnik Vstream Windshield

Get the top rack before you head out to CCR. It will be a real asset. I found that out last summer when Jan and I rode up to Connecticut. I have a top case bag and put all our rain gear in it.

I haven't sold the VStream windshield yet but Jan is really wanting to try the Aeroflow. We are thinking about getting it and the Aeroguards as an early Christmas gift to ourselves. I may be posting a report on it shortly. From things I have read, the Aeroflow windshield with the laminar plate is supposed to be really incredible at reducing buffeting for the rider. I am curious to see what it does for the pillion. I had a laminar lip on my GS windshield and even though I could look over the windshield it really helped because it pushed the wind current above both our helmets.

BTW... I have reduced the price of the VStream windshield I am selling to $125
