BSA BIG END B40/SS90
A BSA B40/SS90 big end part, cataloged under Triumph-style PN 41-0234 — confirm fitment before ordering.
This is a big end part listed for the BSA B40 and SS90, not a Triumph component, even though it's filed in our system under a Triumph-style part number. If you came here searching a Triumph parts book number and landed on this page, double check what you're actually working on before you order.

We don't have much detail beyond that description on file. Big end parts generally live inside the crankcase where the connecting rod meets the crankshaft, but we can't tell you more specifics about this particular piece — size, fit, or which B40/SS90 years it covers — from what's in front of us.
Call the shop and we'll confirm exactly what this is and whether it's right for your bike before you order.
