It sounded in your first post like the bike isn't new, so you are well past the break-in period.
My (2006) 650R had a slightly narrower oil change interval, but I wasn't militant about it. The oil never had any metal particles in it, nor any sludge, and it never burned oil. I'd advise that you keep an eye on the condition of the oil, but you should be fine changing the oil at the intervals advised by the manufacturer.
Focus on enjoying the ride - I've only been without mine for a week and I already miss the rush between 7-10k RPMs.
