A millon opinions are coming!
PS but on a sidenote, any fully synthetic or conventional motor oil is going to be good enough. Just make sure you change your oil regularly along with the filter. I have used everything from full racing synthetic to conventional to the dealership synthetic. Just change every so often. I do every 3k but you cna change ever 500 miles to every 15k miles. Just depends how long you want your bike to last.
