Flanged bolt
Flanged bolt used inside the telescopic front fork leg, also known as the fork restrictor bolt, PN 97-2126.
This is the flanged bolt used in the front fork legs, catalog number 97-2126, also seen listed as H2126. The parts book places it in the telescopic front fork figures, including the versions drawn for T90, T100S, T100T and TR6R, T120R front ends, so it's a fork internals item rather than anything on the outside of the leg.

Other catalog listings for this same part number identify it as a restrictor bolt, tying into the shuttle valve/damping arrangement inside the fork leg. It carries a UNF thread per those listings. If you're rebuilding a fork leg and pulling the internals apart, this is a good one to inspect for wear or damage before you put things back together.
Given the age of the part and how it's tucked inside the fork assembly, check the condition of the bolt and any associated sealing washer while you have the leg open. Confirm which fork figure matches your bike before ordering, since the catalog shows this same number appearing across several different front fork drawings.
