What is it? Kawasaki "High performance lubrication system"?

<<<A 125cc Kawakasi motorcycle has more Hp than a 700 cc mower engine.>>>

It's a tradeoff, isn't it? The mower doesn't need high HP, it needs torque. Hard for me to tell though because I don't see Torque specs on mower engines.

No it is all about cheapness
You could double the torque of a mower engine very easily but it is not done because it adds to the cost .
The big one is fixed engine timing which means that the spark is only ever correct at one particular engine speed

Aren't mowers typically off or run at full speed. All mine have been that way.,

If the timing was exactly right for 3600 rpm it would be near impossible to start
