Gearchange quadrant
A gearchange quadrant from the gearbox outer cover assembly, part of the mechanism that converts pedal movement into gear selection.
The 57-4069 is a gearchange quadrant, the toothed segment that pivots inside the gearbox outer cover and translates the motion of the gear pedal into rotation of the selector mechanism. It's listed under the GEARBOX OUTER COVER figure, which puts it right where the gearchange shaft comes through the cover to meet the rest of the change mechanism.

Older parts books list this one under the T4069 number, so if you're working from an early catalog or a bike with the earlier documentation, that's the same physical piece.
Our catalog record on this one is thin - just the single listing - so we can't speak to which specific models it turns up on. If you're trying to match this against what's in your gearbox, give us a call and we'll help confirm before you order.
