The catalog doesn't tie this specific listing to one named model, so if you're matching it to a particular bike, best to confirm the link count and pitch against what's currently on your machine before you order.
As with any rear chain, keep it adjusted and lubricated, and check sprocket wear at the same time since a stretched chain will chew up sprockets fast.
