Interesting question or not, I'm not too sure??
So the factory recommended motorcycle oils now are very frequently ester based, they are also significantly lower SAPS content than older oils due to the fact modern bikes have catalytic converters fitted.
One can only assume that ester has been used partially to improve lubricity, perhaps to compensate for the reduction of SAPS required to not poison a catalytic converter?
If this is true, how might a low/mid SAPS ester oil compare to a full SAPS traditional 'fully synthetic' oil?
