If an oil's label says it meets JASO MA or JASO MA2 standards then it is okay for wet clutches whether it's conventional or fully synthetic.
The JASO MA and MA2 standards are made up of a series of tests that check for certain frictional characteristics of the oil which have been determined to help ensure compatibility with wet clutch motorcycle transmissions.
Most oils that say 4T (meaning four stroke motorcycle engine) on the front label will also show JASO MA or MA2 on the back label fine print.
