What is the best brand of 15w40 engine oil for a motorcycle?

Some of my friends have said Royal PurpleWhat is the best brand of 15w40 engine oil for a motorcycle?
anything that is not ';energy conserving';


energy conserving oils will hurt the clutch and cause it to slip due to the friction modifiers.





may i suggest motul 5100 or shell rotella TWhat is the best brand of 15w40 engine oil for a motorcycle?
Do you specifically need 15w-40? I would imagine 10w-40 would be just as good.





Best oils out there are Amsoil, and Maxima.
Air cooled bike or water cooled bike? It makes a big difference.
