Here is the Owner Manual for Australia. see page 87 for a temperature and oil weight chart from Honda.
10w40 is what Honda recommends for these parts right up to 120 degrees F. So plenty of good motorcycle specific oils and brands to use in my bike.
I live in Sydney so it's warm in Spring and Autumn, Hot beach weather in Summer and doesn't get much colder than 60 degrees Farhenheit in winter where I am on the coast.
Our local Motorcycle Accessory Supermarket has never even heard of 10w30.
I have only used Castrol since 1972 in everything from the original CB's through to Harleys and now this beautiful machine. Never had an engine rebuild yet.
Full synthetic seems way too expensive at double the price of semi synthetic. Unless you race or thrash it, dont bother.
