I just ordered & installed a Calsci large windshield for my new 2012 C14 after having used the stock one for nearly 900 miles, both one and two up. I'm 6 ft tall with a 32 inch inseam. I had no idea how bad the stock shield was until I rode with the Calsci. The difference is amazing. The stock shield was extremely loud when all the way down (much louder than being in clean air), but flowed decent air on hot days. Raised up to where it was quieter, the stock shield buffeted my head badly, nearly blurring my vision, and there was a lot of back pressure. The Calsci is much quieter all the way down, yet still flows air to just below my neck. It will definitely be hotter this summer, but the trade off otherwise is worth it. Raised all the way up, the Calsci created a completely quiet cockpit with no back pressure, & I was still looking over it. The wife noticed the improvement immediately, as the stock shield buffeted her badly. At max height, she said the cockpit was almost totally quiet for her too. We both agreed this was an excellent purchase.
