FWIW I have always been on the conservative side of the OIL subject, for well over a decade I have been using Motul oils both semi and full synth.
I used full Synth in my last Gixxer and only use semi synth in my Sprint........52,500kms and great gear shifts in every bike I have used it in.
Which IMHO is always a sign of a good M/C oil.
