Motorcycle specific oils are pumped up with five times the anti-wear, anti-scuff and extreme pressure additives of regular motor oil. As an added plus, motorcycle oil does not include molybdenum disulfide and other friction modifiers that wreak havoc on clutch performance.
I'm still forced to wonder what's the difference between "5x anti-wear, scuff and pressure additives" and any "friction modifiers" you wold find in automotive oil. You would reduce "wear and scuff" by lowering friction right? As far as pressures go, I'm not sure a motorcycle would run with pressures so high (relative to a car) that any additive would make a difference. You can run Mobil 1 in a 911 Turbo and not in a 200cc thumper just cuz' it's a motorcycle? And why wouldn't 5x anti wear additives give 5x the same problems on the clutch as synthetic if it's all designed to lower friction anyway? Those anti-wear and scuff additives still get on the clutch plates right? It's not like the motorcycle additives have a "magic" way of only being used in the head of the engine.
