I imagine everyone has their own opinion on how a bike should be broken in. My first couple of bikes I babied like the dealer told me. However, I've changed my approach and ride the bike like I would normally. I wouldn't live at the redline, but I also wont hesitate to push the bike like it was meant to. These have ECUs which adapt to your riding style, so IMO, you should ride it like you would normally.
As far as the dealer telling you a 600 mile service is necessary, I'm sure it wouldn't hurt to bring it in. And I'm sure they wont mind collecting a quick buck from you either.
