Grease nipple
A grease nipple for lubricating pivot points on the frame and swinging fork assembly.
NW100 is a grease nipple, the small threaded fitting that lets you push grease into a pivot point with a gun rather than pulling something apart to lubricate it. It shows up across a long run of catalog entries tied to the swinging fork, suspension units, and frame, so this is one of the fittings you'll find at the swinging arm pivot and other grease points along the rear end and frame of the bike.

Because it turns up in so many figures over more than a decade of catalog listings, this is a part that gets specified again and again rather than one unique to a single spot - if a fitting on your frame or swinging fork looks worn, chewed up, or won't take grease anymore, this is the number to check against.
Later parts books list this same fitting under 28-2080, so if your book or an older parts diagram shows NW100, know that it's the same physical part carried forward under the new number.
