Honda CBR 125 RW9 how often to change oil?

How often to change the oil on a Honda CBR 125 RW9? Can't seem to find anything in my owners manual.

With all my bikes, I do it once a year or every 3000 miles, which ever comes first. I also do the filter along with it.

Every 3-4,000 miles is a good policy, I change the filter every other oil-change.

Between 2500miles or 3000miles.
