Our catalog entry on this one is brief, so beyond the compression ratio and the fact that it's a set of pistons for the BSA 650, we don't have more detail on file. If you're working on an A65 or similar 650 twin, give the shop a call and we'll help confirm what you've got before you order.
Worth noting the "L" in the part number may point to a specific size or oversize designation, but we can't confirm that from what's in front of us, so don't assume anything there without checking with us first.
Sorry if we got something wrong here. If you think this information isn't correct, .
