Good idea, it is 3.5" long so it doesn't look like the long portion of the arm is going to be long enough.  I think that's going to be the problem with all of the special mounting kits that MRA sells.

OK. Last questions.
What is the exact diameter of the arm?
And how is it maintained on the ball?
The other option could be that I take the HKSI, and make longer arms (I can find a way to bend them)...

The arm is exactly 9mm in diameter using my digital calipers.  I don't know how the plastic ball is attached to the rod.  It could be glued or it could be threaded.  Personally, I think I would try heating up the straight arm and bending it.

PS - another option would be to cut the long portion of the rod and use a die to cut threads on the ends of the cut pieces and then use a threaded coupler to gain the additional length needed.

Good idea! But 9mm is not a common diameter. I have taps and dies in 8mm and 10mm.
I have now to find 9mm inox bar,  tap and die, but it appears that it is more expensive than buying an additional HKSL kit with long arms !

Right there's no easy solution.  I suppose you could cut 8mm threads in a 9mm diameter rod.

I've now been commuting for about a week with the new windscreen so I thought I would wrap up this tread with a brief summary.  The bottom line is I like the MRA windscreen a lot.  I think it is an excellent option for the Zero FX/S model.  It's not perfect, but I don't think any windscreen will be.  The addition of the X-Creen provides decent wind protection for taller riders.  I'm still having a little bit of an issue with the windscreen wanting to rotate due to wind or bumps.  I added a star washer between the handlebar clamp and rod clamp which helped some but the teeth on the washer I used aren't very aggressive.  I think if I used a more aggressive serrated washer it would be fine.  Here is what I ended up using.  All parts came from Twisted Throttle with free shipping and no sales tax (to Ohio anyway).

I have received today a MRA V-Flow Typ C, and the standard HK mounting kit.
I have mounted it quickly (the two arms are not perfectly on the same level and I have to adjust them a little bit later) and have taken some pictures.
I want to try first without the X-Creen. If the protection is sufficient, I will keep it like that.

Looking good there.

After some days of experiment with the MRA V-Flow Typ C (without the X-Creen), I am quite satisfied.
The screen did not rotate. But in the bumps, it moves a little bit, and consequently it can hit the bike if it is mounted too close from the bike.
Wind protection is good for me (I am 170 cm tall). Last day I was riding in the cold, and I opened the visor of my helmet a little bit to remove the fog inside. 20 kms later I realized that I was still riding with the opened visor, and, despite the cold weather, I was not feeling the wind at all!

have you noticed a decrease or increase in range with the windshield?

[gt13013]

No, I have no regular travel, and consequently no way to detect some change concerning the range.
