It works at the center of the clutch assembly to set the free play on the pushrod, letting you dial in the clutch action so it releases cleanly without dragging. It's a small part but one that gets adjusted and re-adjusted over the life of a clutch, so it's worth having a fresh one on hand rather than fighting with a worn or buggered-up original.
We don't have more specific model-year fitment tied to this catalog entry beyond the span above, so if you're matching it to a particular bike, give us a call and we'll confirm before you order.
