AIR FILTER K&N 900 OFFSET
A K&N 900-offset-pattern reusable air filter, listed under PN 83-1537KN.
This is a K&N air filter, listed in our records as the 900 offset pattern, carrying the number 83-1537KN with an alternate catalog form of 633-RC33. K&N filters like this one use a reusable cotton-gauze element in place of the stock paper cartridge, and owners running one typically service it by cleaning and re-oiling rather than replacing it outright.

We don't have much beyond the catalog listing itself on this one, so we can't speak to which carb setup or airbox the offset shape is meant to clear. If you're trying to match this to what's currently on your bike, give us a call and we'll sort out fitment before you order.
Worth keeping in mind that "offset" in the name usually points to a filter shaped to clear something nearby, like a frame tube or carb body, rather than a straight round element — but confirm that against what you're replacing before you commit.
