This is my technique. During your break in period, change oil and filter before reaching 500km in your odometer (mine is 300km). After that, ride your bike for a long period of time (e.g. 4hrs non-stop riding) so that the new oil will penetrate thoroughly to the engine as it gets hotter. When you reach 1000km, change oil again and change filter and do a long rides again after that. When you reach 2000km, change oil and filter again and by that time, your engine is properly breaked-in. So your next succeeding change oil and filter will be 1500km-2000km. It sounds effective but it will help your engine runs better for life.
Hope this helps.
