G'day all

These are only observations.
To my knowledge, no 125cc was contemplated.

By about 1975-76 Victa had the larger 170cc Twin.
By 1977-78 Victa had the smaller 85cc engine.
With the 125cc and 160cc that made four engines in the line-up.

I feel Victa learnt something from this, or were forced to
take note from other lawnmower makers and the market in general.

It was this: you can have very successful market differentiation
at a much cheaper price if you focus on cosmetic changes, and/or
cheaper-to-make specification changes.

Today, we see this in lawnmowers ... but we also see it everywhere.
The mere change of dress cowls, colour, wheel sizes, options, etc.,
all could deliver a 'range' more economically than the economies-of-
scale loss in having to produce distinct engine sizes.

Being a cynic, I might also add that, today, identical products
can be packaged and marketed differently and to different classes
of consumer. It's all about deception and perception.

Interesting question
