Wind protection is much better than naked. Before I put the fairing on, the bike would only do 140ish, after the fairing I managed just over 150 'indicated' in a full tuck. Nowadays, after removing the SAI, custom map, etc. the bike will do 140+ ACTUAL in a full tuck with no fairing. I'll be getting a Puig Alien Streetfighter screen hopefully in the next month to finish off my front end swap. Thats why I'm selling the Roadracing screen and already sold my headlights.
Wind noise is noisier with the Roadracing screen, but this is because it deflects the wind up to your face shield and top of the helmet when you're sitting upright. A slight tuck gets you under the wind. I can't remember, but I don't think you can use clip-ons with the Roadracing screen as the bars would hit the sides of it.
The overall build quality is good, the shaping of the aluminum pieces of the fairing is obviously stamped out using a die as I don't know of anyone who can make such perfect compound creases in aluminum by hand. The only piece I thought could be nicer would be the support bracket. It doesn't come with an integrated mount for the guages (mount is separate and mounts to the underside of the top triple clamp). The welds weren't as beautiful as I'd like, but overall the thing is solid and suits the look of the bike. It is a complete replacement for the stock headlight/cluster bracket.
