Hey guys, I am new here, just purchased a 2016 KTM 450SXF from my local dealer. The very first day I brought it home, before even unloading it out of my truck, I noticed an audible ticking sound coming from the engine compartment at idle. It sounds like a valve train tick. The ticking is consistent with the RPM and does it riding or idling. The sound seems to be at the top of the engine. Anyone else with the new KTM have this ticking? I called the dealer and sent them a video, he said everything sounds normal. My gut is telling me it is not normal. I'm trying to get this figured out before my 30 day "warranty" is up. Any help would be awesome!

You can hear it the best in this video.
Here are two more links:

Maybe check your oil level, valve clearance and timing change tension. If it's running fine fine and everything checks out, you should be fine.
I dont know for sure but my 2016 250 sx-f did same thing. But i didn't pay attention(big mistake). And it got worse way worse. Then i went to the dealer and they said its sand damage(sand getting into engine). I was pretty sure it wasnt sand, not the first bike. I know how to wash filters. And i had a recall to my bike also. Dealer did not inform me. Now i am 1500 eur poorer. Dealer lying, Austria KTM dosent giva a f.... (Happend in Estonia).
So my advice. Take it back or make somekind of deal if it get worse. It will have warranty. There have been problems.
But last thing. KTMs do have a little ticking sound.(thats the reason,why its hard to say. Video will disort the sound)
Dont want to scare you, but just had very bad experience and dont want anybody else to have it.(sorry for my english)
IMO something is wrong with the engine. I am not familiar with KTM 4 strokes so I cant say what it might be. If my brand new bike was making an abnormal noise, I would have taken it straight back to the dealer without riding it another second. In fact, I would have started it at the dealer with a technician standing beside me before I rolled it up the ramp into the truck bed. Looks like you have continued to ride the bike a couple of hours and performed the first oil change yourself. Hopefully your dealer is a stand up company that doesn't take issue with that. Many dealers in my area would probably say "sorry, warranty has been voided." Good luck!

Take it back do dealer. Its brand new bike and cost you a lot of money.
If you don't find any loose parts, take that thing in to the shop you bought it from and have them listen to it.
They probably have another low hours 2016 sitting there. Ask them to hear another same model/year run to reassure you that they sound the same.
The clutch sound other guys are talking about is in every single bike made, but way more audible in four strokes. It is due to designed backlash between the primary drive and driven gear (crank and clutch basket). There is a torsional vibration as the engine decelerates in compression stroke and accelerates in power stroke. Since the clutch assembly has a bunch of inertia it wants to run at a constant speed and the gears bounce across the backlash gap. Pulling in the clutch lever reduces the inertia of the clutch assembly by decoupling the steel driven plates and the hub/pressure plate/spring assembly.
Thanks again fellas.
get a nice manual cam chain tensioner and I bet your sound goes away.
Off topic, but does anyone ride around the Southeast Texas, Southwest Louisiana area in here? I'd like a few more people to ride with locally. I usually make the drive to Three Palms in North Houston, but it's getting harder and harder to motivate myself to drive three hours to ride by myself..
What area are you in?
