The design engineers want insure you don't go buy Supertech 20w50 and run it like a lot of guys do with other bikes and then turn in a warranty claim when it blows . So they spec an oil that is only made in real high standards usually synthetic and not openly distributed. Then they stock it at their dealers with a nice mark up.
