Hi, and welcome to the forums!
You'll not find a better class of folks than here
, and with all the help and advice you can funnel down your throat.
Isolating your keys is a good start. I had a rattle that drove me nuts until I got a leather wrap around all the extra ones on the ring.
Other items to check...
- All the hardware on your front mud guard. And use some blue thread locker on ALL of them. You can get his from any hardware or auto parts store. If your dealer did a proper setup it may have already been done.
- Your front wheel axle pinch bolt for tightness. If loose it'll ring just as you described.
- Anything from the handle bars all the way down to the bottom of your axle.
And, as suggested, if you're relatively close to your dealer, take it back for warranty consideration.
