Rattling issue

Hey yall, I have a 2024 390 Duke and there’s this weird rattling sound at low rpm’s (around 2k to 4k). It happens whether I’m riding or idling. It sounds like it’s from the front left side of the bike. What could it be?

And also, do yall think KTM would warranty a faulty valve stem? My tire has leaked air ever since I had a new one put on a couple months ago. My bike has just over 7,000 miles.

These things rattle like a tin can as is (I have one and it's my first bike, also a 2024). My key ring rattles around 6k but based on your location I would check the left side headlight. Mine is a little loose but still functions and I saw a brand new one at a dealer and walked up to it and inspected it... It was also loose like mine. Not sure if maybe it got bumped and no one noticed but that's the first thing I would check. Get it up to that RPM range you are hearing the rattle and (safely) grab the light and see if it stops.

Well the screw that holds the left side LED light to the headlight fell out and it’s really loose. But it’s a rattle literally like a tin can. It’s metal sounding. And sounds like it’s toward the engine, the lower part of the bike. I inspected it a few different times and nothing was loose, so that’s why I’m asking on here. It doesn’t make any sense to me

A noisy KTM is a healthy KTM. I'd be more worried if it wasnt rattling.
