Brake torque stay
A rear brake torque stay (83-1780, formerly F11780) that anchors the brake backplate against rotation.
This is a brake torque stay, listed under 83-1780 with the earlier factory alias F11780. It shows up in the swinging arm, suspension units and chainguard section of the parts book, which puts it at the rear end of the bike where the swinging arm and rear brake assembly live.

A torque stay's job is to anchor the brake backplate or drum so it can't rotate with the wheel under braking load - it ties the fixed part of the brake to the frame or swinging arm. The catalog only shows this one on a single listing for the 1974 model year, so we don't have a lot of cross-reference data to lean on beyond that.
If you're trying to match this up to your bike, it's worth checking it against your actual rear brake and swinging arm setup before ordering, since we only have the one catalog entry to go on. Give the shop a call if you want to confirm fitment.
