If you research SYN oils, the oils were delevoped to reduce friction-to allow more free running of the engine, run the engine cooler, which theoretically produce more H.P./torque.
So i would agree with "noticable".
On a different note- Has anyone noticed, when you changed your bike from Conven' oil to the SYN oil, of the change in exhaust smell ??
When I changed all my bikes to Motul 300V (green blood-as my kids call it) and the smell that aroused in the shop.. Sweet,aroma..
