PISTON BSA B40/040
Piston for the BSA B40, listed in the 040 size.
PN · 41-0252
This is a piston for the BSA B40, not a Triumph part despite how it's filed in our system. The description we have on it is brief - it just identifies it as a piston for the B40 in the 040 size designation, which typically refers to an overbore size in these old British catalogs.
$99.49
