An outer gearbox cover like this bolts over the gearbox to close it up and keep road grime and water out while giving you a place to check or top off the oil without pulling the whole case apart. Beyond that basic function we don't have more detail on file for this specific casting.
If you're matching this up to your bike, give us a call and we'll confirm fitment before you order. With gearbox covers, small casting or mounting differences between years can matter, and we'd rather check than guess.
