I don't think the specific brand of oil matters much. Use any synthetic designed for motorcycles, and change it regularly, and you'll be fine. Use the weight of oil your manual recommends, maybe switch to a lighter weight in the winter if you ride when it's cold out.
I change mine very 5K to 6K, which for me is 2 to 3 times a year. If you only ride 2K a year, change it at least once a year. If you have to store it for the winter, change the oil at least once, either just before storage, or just after taking it out (I prefer the latter. If you're persnickety, do both).
By this method, I've gotten over 80K on three previous bikes (1989 Honda CBR600, 1979 BMW R65, and 1960 Heinkel Tourist 103A1), and my current bike is at 237K so far, without an engine rebuild ever.
