ROD INSERTS BSA A65 STD.
Standard-size big-end bearing shell set for BSA A65 (and related A10/A50) twins, part number 67-1430.
This is a set of standard-size big-end (connecting rod) bearing shells for BSA twins, not a Triumph part despite what our own manufacturer field might suggest. The canonical description ties it directly to the BSA A65, and other catalog listings for this same part number extend that to A10, A50, and A65 models as well.

The big-end bearing shells sit inside the connecting rod, riding on the crankpin, and are one of the parts most directly responsible for how smooth and quiet the bottom end runs. These are standard size, meaning they're meant for a crankpin that hasn't been reground undersize.
We don't have much more detail on file for this one beyond the description and its cross-listing under other rod-inserts part numbers in the same family. If you're not certain which of the related standard/undersize numbers matches your crank, call the shop and we'll sort it out before you order.
