Our catalog record for this one is thin, just a single appearance tied to the 1970 model year, with no other details on hand. Given the BSA tag on this listing, it may belong to a BSA machine rather than a Triumph, but we can't confirm that from what we have.
If you're trying to match this up to a specific bike, give us a call and we'll go over the fitment with you before you order.
Sorry if we got something wrong here. If you think this information isn't correct, .
