PISTONS AJS TWIN 9:1 +010
A 0.010 in. oversize, 9:1 compression piston listed for AJS twin engines, not a Triumph part.
This one is out of our usual lane. The catalog entry reads PISTONS AJS TWIN 9:1 +010, which points to a piston for an AJS twin engine, not a Triumph. The +010 marks it as a 0.010 in. oversize piston, and 9:1 is the compression ratio it's built for.

We don't carry deep stock or history on AJS twin engine parts, so we can't speak to specific model years or bore sizes from what's on hand here. If you're rebuilding an AJS twin top end and this number matches your parts book, it's worth a call before you order so we can confirm what we actually have and whether it suits your engine.
Given the numbering (R1035/010, also seen as R1035.010), this looks like a sized variant within a piston set numbering scheme, but we're not going to guess beyond what's printed. Ring us and we'll sort out the details together.
