Motul Oils in 3100 series which come with M033MOTxxx JASO certification# are from France licence => perhaps pricier.
Motul Scooter expert 10w30 JASO-MB had Singapore licence & it was cheaper like local minerals.
Try to lean towards JASO-MA2(2011) for wet-clutch motorcycles. Not sure if 3100 are equivalent to 5100 series, but definitely not better.


enjoy the ride!
