It's the stock screen from the B1200 Sport. Same screen for the 2v, and 4 valve. I picked up one and mounted it on my B1100. I like it. It works well for it's size and looks great.
I was lucky to pick up the whole kit off a totaled B sport for far less. It helps to develop a relationship with a quality dealer/ service shop.
