We don't have much more detail on this one in our records beyond the description and the oversize spec. If you're piecing together a rebuild, give us a call and we'll confirm what's actually in the box before you order.

Note this one is filed for the BSA A10, not a Triumph twin, so double check it against your own parts book before ordering if you're not sure.
