Hi all,

I was hoping somebody with a a bit of JASO T 903:2006 knowledge will be able to help me on this one.

I have looked and looked but can't find any information on how motorcycle oil frictional properties are measured.

I understand Motorcycle JASO oils are categorised into Grades MA, MA1, MA2 & MB from their frictional characteristics but what i'm struggling to find is information on how this oil friction is measured/tested?

Is there a piece of apparatus that is designed to test the following of a given oil sample?

Dynamic Friction Characteristic Index (DFI)
Static Friction Characteristic Index (SFI)
Stop Time Index (STI)

Thank you in advance.

The SAE #2 Clutch Friction Tester is used to test for all three frictional characteristics.
