BUSH,MAIN BSA A65 -.010 KWPM
Main bearing bush for the BSA A65 twin, .010 undersize (KWPM).
This is a main bearing bush for the BSA A65 twin, machined .010 undersize. The catalog entry marks it as a KWPM part, and the -.010 designation tells you it's ground for a crank or housing that's already been taken down that amount during a rebuild, not a standard-size replacement.

Our records on this one are thin - it's a single terse catalog line without the usual figure references we lean on for the fuller story. If you're rebuilding a bottom end and need to confirm this is the right undersize for your crank, give us a call and we'll sort out fitment before you order.
Note this is a BSA A65 part, not a Triumph piece, despite how it's filed here.
