We don't have detailed catalog history on this one beyond the description and its listing as a rear brake assembly component. If you're trying to match this up to a specific bike or drum diameter, call the shop and we'll go over what you've got before you order.
Given it's a billet piece, it likely turns up as a performance or replacement upgrade rather than a stock factory part, but we'd rather confirm fitment with you directly than guess at specifics we don't have on file.
