This is a piston ring set for the Triumph 750 unit twin, sized at +.040 over standard bore. The catalog lists it against the T140 family, which puts it in the 750cc unit-construction twins rather than the smaller 650 or 500 twins. Ring sets like this go in when a cylinder has been bored oversize to clean up wear or damage, and the +.040 marking tells you exactly which bore size these rings were ground to match.

The set is made by Goetze, manufactured in Italy, and comes through under a JRC part number with a couple of alternate reference numbers on file as well. If your parts book or an old invoice shows WW97081R or R26490/040, that's the same ring set.

We don't have much more background on this one beyond what's on the box. If you're not certain your bore has already been taken out to +.040, get it measured before ordering — ring sets are ground to a specific oversize and won't split the difference.
