Pivot bolt
A pivot bolt used in footpeg and exhaust-bracket fittings on the T100C, catalog number 21-1971.
This is a pivot bolt, catalog number 21-1971, also listed as S1971 in older references. It turns up in the exhaust pipe and footpeg fittings for the T100C, and also in the general engine unit fittings and footrests listing, so it's doing pivot duty somewhere around the footrest or exhaust bracket mounting rather than deep in the engine itself.

A pivot bolt like this gives whatever it's fitted to a mounting point that can swing or rotate slightly, which on a bike usually means a footpeg, a bracket, or a lever assembly rather than a fixed structural bolt. Given the two figures it shows up in, it's most likely holding a footpeg or exhaust-related bracket in place while letting it pivot as needed.
Our records don't spell out thread size, length, or material for this one, so if you're ordering to match an old bolt, bring it in or have your parts book handy so we can confirm you're getting the right one before it ships.
