For the full crank engines, as far as the 125 being a 'better engine', it was of course not as powerful as the 160, but it was more durable.
A 125 could usually have several replacement sets of piston rings before needing a rebore. The 160 bores tended to wear oval, so if the rings were gone, it would almost always need a rebore.
G'day Gadge,
yep, that is what he must have been getting at, I think, although he seemed to also imply they were better all round too. It was too good for a limited lifespan for future sales. It was quite a fascinating thing to hear, considering they were positioned for the entry level models. One of the mowers that captured my imagination was the 73-74 VC 125 mark III for it's sound and styling. I also liked that lip it had in the black cowl to accommodate the decompression valve inside.
P.S Does the powertorque fare better with it's bore? At least it has (slightly) extra grunt on offer over both full cranks, but has it's half crank design to jeopardise durability.
