So far so good
Sprocket fit great and had no factory defects. I have three races and multiple practice days on it now and it is showing no signs of wear.

Renthal Rules!
Bought this a month ago to replace the sun star sprocket that came with the bike from factory. Have several rides on it now and it still looks like new. Worth every penny!

does this come with mounting hardwear
No you have to use your own sprocket bolts. Just remove old sprocket and reuse the bolts to install this one.
