The book doesn't call for it but it is a good idea. Generally an oil change after break-in (1000 miles) and then every 3,000 miles. The manufacturer doesn't really care if the bike last more than the first year. They will sell you another when this one wears out.
I change my oil about three times a riding season, or more if I feel it is necessary. Just keep an eye on the color and condition of your oil. If it's really black, then change it.
