Just like API here in the US, JASO has categories. For a reason. You can buy API oil in straight 30 weight that might meet API SE. But that is considered obsolete. Current designations are SL, SJ, SM, and SN. Manufacturers will state what is approved. For instance, they may approve an API SM oil, but not an API SN! Due to levels of certain additives either missing to too high to meet their standard.
For our purpose ( riding and maintaining motorcycles ) JASO has only to due with friction modifiers. Those components that lessen friction to meet energy conserving standards for one, and another type that can leave behind a coating or film on parts ( like Moly ).
The absolute worst thing that can happen with a non JASO approved motorcycle oil is you coat the clutch plates and they slip some. Even that is HIGHLY unlikely, as much as I deal with clutches I have yet to come across a confirmed case of that.
Then there is viscosity........
