I have a rattle as well

Mine is getting a little worst, and seems it's moving higher on rpms.
First was there at exactly 5500rpm, now up to 6000, in basically every gear.
It feels to me like something not fixed properly that starts vibrating, even if it is not worrying me so much: I read it is common.
Must be said that I didn't lube the chain yet, at 400 km.
After doing so I will check again and report.

The bad thing here is that you can't check what it is while riding, and when you're off and could check you're not riding so the noise isn't there.
I am with ceebeearr when he sais it tends to get worse, but is seems just something metallic not properly fixed that, at certain rpm/torque/vibrations start ticking.
I don't feel it coming from the engine, anyway.
Someone should take it on a dyno and record it with a camera

I was suggesting to put it on a dyno and record it with a camera while running through gears to have a visual check of what can vibrate at that rpm.
I am still not convinced it's IN the engine, but that it's AROUND that. I clearly hear the engine running smooth, when I ope throttle and when I leave it, but the vibrating noise is there: that's why I am not complaining.

Second thing: the vibrating sequence is constant: if it was rpm-related, should have varied through rpm intervals: starting slower than becoming faster at higher rpms. I can't recall anything like that.
