Automotive motor oils contain friction modifiers that are not compatible with wet clutch setups used on many motorcycles; hence the need for motorcycle specific oils. I plan to use full synthetic motorcycle grade oil in my bike. Each to his own but I have used synthetics for years in all my autos and never had an oil related issue. Synthetics are far superior to standard oil at handling heat and have far greater shear strength. While I am sure the Honda specific oil is good, I plan to us a 10W30 full synthetic made by Repsol, Amsoil, or Castrol in my bike.
