It's at 50,00 kilometers now. The fairings are new and I put a lot of heat shield on them. From the hundreds of posts on the 'net from people that bought the bikes new - it sounds like it's pretty common.
One fellow with an '08 CBR 1000 RR actually cased it. Apparently they all
make that noise much to the annoyance of the owners. He cased it by replacing the entire timing chain assembly. The chain, the cam gears, the crank gear, the tensioner and all the guides. In short he kitchen-sinked it. But, it was widely regarded as the only one that didn't make that noise
Apparently when he sold it the prospective buyer noticed it right away as he had test-driven quite a few before settling on his.
I was tossing around the idea of doing the same thing - just replace it all. I already have a new tensioner and it would not be too hard to replace it all. Thing is, I had to order up a Carbon Fiber clutch as the OE one is really bad now. The good news is that Barnett is now making one (Carbon Fiber) the bad news is it ate enough money that I'm going to have to wait on the 5K timing noise until later
I'd really like to get rid of that damn whine/rattle - when I had the cams out for the valve clearance adjustment I did see a fair bit of wear on the backside of the guide where the tensioner pushes on it. I wonder if replacing that alone would do it but it would probably be better to just kitchen sink the damn thing and hopefully see exactly what causes the issue via wear on the old parts (most of which you can't see unless removed).
It was good to see that a lot of other people reported the same noise right from the showroom floor. There was also an interesting commonality though on the reports. Many people started reporting the noise immediately after the first oil change service from the dealer. That was a very common 'trigger' when people started complaining. Makes me wonder if Honda used a 'special' oil when they filled them at the factory. I've seen a lot of instances where GM and other OEM's have done the same.
I also thought it should be transmission but when I saw how many people posted about the same noise back when the bikes were new a lot of people said that's just the common timing chain noise - they all do it.
