The markings on the box indicate this is a kinetic cylinder. The first one I got was the machined off- center, so it didn’t sit square in the case, and more importantly, one of the cylinder stud holes was drilled into the exhaust passage. The excellent Treatlander customer service people Sent me another one...same issues. The transfers are also significantly smaller and shaped slightly differently from my stock Vespa cylinder. I’m returning them and getting the 50cc DR kit instead. Maybe you’ll be luckier than me.
Quality control lacking
