I have an aerflow still in the box--it looks like a quality item, but I have not put it on, so I have no clew how well it works. If you could go back in time, or back into eBay, you might find an old SAENG fairing. I must have put 30 K or more on my Saeng, and always found them to be good protection in the winters here in Md. If you did find one, be sure that it is set up to fit your model bike. The handlebar mounts were all custom made to each particular model, so they won't go from bike to bike easily.
Just one opinion....Ed out.
