This one's a piston for the BSA A10, not a Triumph part, so if you landed here looking for something to go in a Bonneville or a Tiger, this isn't it. The catalog entry we have is brief - it lists an 8.5 compression ratio and a +080 oversize, which tells you it's meant for a cylinder that's already been bored out that far during a rebuild.

We don't have much more detail on this one beyond what's in the description. If you're rebuilding an A10 top end and need to confirm this piston matches your bore and compression setup, give us a call and we'll sort out the fitment before you order.
