Use any oil that meets the spec in your owners manual. I've used "car" oil in all my bikes for years. Wet clutch and dry and I've never had a problem except I've saved a crap load of money. But many will tell you that if there isn't a picture of a motorcycle on it and it doesn't cost twice as much you will die in a fiery engine explosion...
