I can't exactly answer your question. Just yet.
I have the Klock on my 17' RGU. Finally got some real road miles behind it this last weekend. I really like the looks of it and by myself its tolerable. Without helmet. Helmet and I get blurry vision unless I slouch. I'm ~6'1'. It will be pulled and replaced with the 12" LRS tomorrow. Around town and its just me, the Klock looks and works ok. I can ride with a ball cap no problem. It gives my passenger no happiness.
The thing is, I have the hardtail chopper, and around town the RGU gets as many thumbs up as the GSXR. Nor does it get any post cards.
I will say after ordering the LRS, they did follow up with communication asking if i was happy with it. Something to be said about that. If this shield I have from LRS does not cut it, I will not hesitate to order a taller one from them.
