Okay now I've had three shields on the bike trying to see which would push the air up onto the top of my helmet and right now the ZG Touring is doing the best job. The shield material is not as thick as the Suzuki Sport Touring one but has a steeper angle which deflects the air. There is some turbulence behind the shield and I've not sure if that hasn't come from the tank bag. Anyways I'd like to try the Laminar Lip on the Suzuki Sport Touring shield and that might prove most effective. I also think if I had a Torbin and got lower they all probably would do the job for some distance running. Wardie
