PISTONS TRI 650 10:1 .010

A .010 oversize, 10:1 compression piston for the Triumph 650 twin.

PN · R1611/010
Available in 7 sizes (rebore oversizes):

This is a piston listing for the Triumph 650 twin, ground to a 10:1 compression ratio and sized at the .010 oversize step. That oversize marking means it's meant to go into a cylinder bore that's already been rebored .010 over standard to clean up wear, so check what your barrels have been machined to before ordering.

We don't have much more written down on this one beyond the basic listing, so if you're piecing together a rebuild, give us a call and we'll walk through bore size, ring pack, and gudgeon pin fit with you before it ships.
