For my new KTM 690 the manufacturer says not to exceed 6krpm for the first 1000km (first service) and then not to exceed 7.5krpm for the next 1000km - and that is all. I was surprised that it was 6k not 4.5 or 5 but riding the bike it seems right. I'm just riding normally using all the gears, engine braking etc. just not wringing it through the gears. Oil is fine for the first 1000km. Even though the rings are not bedded you get very little petrol contamination in a new engine. Any 'swarf' that may find its way into the oil will be filtered out.
Race engines need much less running in as the 'blueprinting' process ensures that everything is within very tight tolerances from the outset and bores and rings are finished to a much higher spec than a mass produced engine.
