PRIMARY CHAIN 250 TRI/BSA JAPAN 70L - Replaces 19-8613
70-link, 250-size primary chain for Triumph and BSA, replacing 19-8613.
This is a 70-link primary chain in the 250 size, listed for both Triumph and BSA applications. It's the drive chain that runs in the primary case between the engine sprocket and the clutch, transmitting power from the crank to the gearbox before the final drive chain takes over. The catalog notes this number replaces 19-8613, so if your parts book or an old chain still shows that number, this is the current equivalent.
