Our catalog record on this one is brief - just the part number and description, with no material, size, or thread details given. The manufacturer tag on file says BSA, but the description itself doesn't name a specific model or bike, so we can't confirm exact fitment from what's in front of us.
If you're trying to match this to your bike, give us a call and we'll work through it with you before you order.
