If the Pioneer/Partner chart is accurate, the first sub-55cc saw was the 5000 so whatever it is, it's likely be at least 55cc.
While the chart is Handy, it is missing some information. A few of the R series are left off of it completely. R15, R18, R19, R22, R30. Those are what I know off the top of my head. I'd like to be able to fill in more of that information. I will be picking up a nice looking R22 next weekend so I can add that information.
