PISTON SET STD 7-1 T120
Standard-size 7:1 compression piston set with rings for the Triumph 650 twin, also listed as 70-3610.
This is a standard-size 7:1 compression piston set for the Triumph 650 twin, sold under the alias 70-3610 as well as the JRC 650/L catalog number. Compression ratio and bore are both called out right in the description, so this set is built to the lower-compression spec rather than the hotter 9:1 pistons some of these engines got later on.

A piston set like this comes complete with rings, and covers all the pistons needed for a rebuild rather than a single cylinder. Because it's listed at standard size, it's meant for a bore that hasn't been machined oversize yet.
Our record on this one is thin beyond the description itself, so if you're matching it to a specific engine or year, give us a call and we'll walk through it with you before you order.
