If anything, it is NOT Sanye keeping a finger on the pulse, at least not the Sanye that used to produce those engines.
If the "about us" page is anywhere truthful, this is a new owner and a new company basically taking over part of the name for recognizability.

Given that they started with the 52, they seem to absolutely do some research, AFAIK that was basically their highest volumes selling engine.

The 80, twin and radial all used the same pistons and liners, so that were logical restarts as well, especially the twin also being a pretty decent selling piece of kit (and based on my personal experience a deadreliable very hard wearing and durable engine).
