Our record only ties this part number to one catalog appearance, tagged to 1971, and the description doesn't spell out which specific bike it was fitted to beyond that. If you're matching this up to a machine, check your own sprocket count and chain length before ordering, since final drive chains vary by model even within the same era.
Keep an eye on chain condition and lubrication generally — a stretched or dry final drive chain wears sprockets fast and can throw the whole drivetrain out of alignment.
