A friend of mine has it, and I don't like it at all. My MRA windscreen gives much better wind protection and it is much cheaper. And I think it looks better Zero Gravity is also an option
My dealer actually recommended the Zero Gravity over the genuine screen when I bought the bike. Not sure of the price differential as I didn't ask but the Zero G Corsa in dark smoke from my dealer was £80. I was very happy with it until the unfortunate incident with the defective paddock stand ended up with the bike on it's side with the screen split almost in two.
The stand manufacturer will be replacing it and I'll be going for the same model again. Unless they're out of stock.
