He also told me that PBR produces two similars sprockets in a different price range. But the more expensive has more specialized hardening (like the one I bought)I have run them on last Gixxer 11 , they were fine on that bike , your one looks even better anodized color to what I remember .
I say this because I saw it on ebay similar sprocket pbr for about $ 50. It's not the same sprocket..
