Piston Complete C.R. 9:1
A complete 9:1 compression ratio piston listed in Triumph's crankshaft and connecting rod parts records for 1967.
This is a complete piston, listed in the catalog as a 9:1 compression ratio piston. It shows up in the crankshaft and connecting rod section of the parts book, which tells you it's part of the reciprocating assembly down in the bottom end rather than a top-end-only item, though a piston naturally works with the bore and head above it too.

The catalog carries this one under 70-6897, with E6897 as the earlier alias form of the same part. Appearances in our records are limited to 1967, so that's what we can confirm from the books we have.
Beyond the compression ratio called out in the description, we don't have bore size, material spec, or model fitment nailed down in our records for this one. If you're rebuilding a bottom end and need to match compression ratio and bore together, give us a call and we'll confirm fitment before you order.
