Kickstart quadrant, B50 (1971–72, 3/4)
Kickstart quadrant for the B50, 1971-72, 3/4 version, also known by the older T4341 reference.
This is a kickstart quadrant listed for the B50 in the parts records, covering 1971 to 1972. The catalog description marks it as the 3/4 version, which tells us there was more than one variant used across that span, so it pays to check what's currently on the bike before ordering.

The kickstart quadrant is the toothed segment that engages with the kickstart shaft assembly, translating the swing of the kickstart lever into rotation that turns the engine over to start it. It lives down in the gear cluster and timing cover area of the engine, which is where this part shows up in the parts book figures.
This one also carries the older T4341 reference from the earlier numbering system, so if you're working from a vintage parts book and see that number, it's the same physical piece as 57-4341. Because the catalog only ties this to the B50 across a narrow year window, and there's more than one version noted, give us a call if you're not sure which one your engine takes.
