BIGEND,B50 BSA STEEL CAGE
Big end bearing assembly with steel cage for the BSA B50 single.
This is a big end assembly for the BSA B50, built with a steel cage. The big end is the bearing that connects the connecting rod to the crankshaft, and it takes the brunt of the pounding every time that piston fires. We don't have much more in our records beyond the description itself, so if you're not sure this is the exact version your B50 needs, give the shop a call and we'll sort out fitment before you order.

This is a BSA part, not a Triumph part, so if you came here through a Triumph search you're in the wrong place — B50 is a BSA single, not anything in the Triumph twin or triple lineup.
Given how little detail we have on file for this one, treat this page as a starting point rather than the full story. Call us with your engine details and we'll confirm before you commit to ordering.
