PRIMARY CHAIN, BSA, A50 A65, TRIPLEX, 80 LINK, ENDLESS, BS, 19-8639, ENG0054

Replaces BSA OEM Part No: 19-8639

Triple row primary chain, 80 links, endless.

This is a British standard measure OEM spec chain, made to meet or exceed Renolds breaking load specifications...Same quality as Renolds for a fraction of the price!

This chain is not metric. The use of metric chains such as DID and RK etc on British motorcycles will result in premature sprocket wear.

FYI: Duplex and Triplex primary chains are endless. This means there is no connecting link. The connecting link is the weakest link in a chain. Avoid using connecting links in your primary case whenever possible. The damage caused by a chain breaking inside the primary case can be avoided by the use of an endless chain.

Please use your parts book to verify correct fitment for your model.

These are not inferior chains as sold elsewhere. Made in Japan.

Brand new. Superior OEM quality.
