Metallic Sound when revs is going down

I'm hearing a metallic sound, like a coin hitting a metallic surface many times per second, when the revs is going down.
With the bike stopped, neutral gear, rev up until 4000rpm and let it down. It sounds like something is not tie enough.

It sounds like this one:

It is normal?

Never. Did this just start happening - or has it always been present.
If it's still under warranty, I'd take it back to the dealer. If not, have an experience mechanic check it.

The chain and sprockets are worn out. The sharp ticking sounds are coming from the person with camera which is also cutting out a bit.
Your chain is unevenly stretched, causing it to go tight, loose, tight, loose every time it turns, and I can also hear the chain snagging on your front sprocket.

If, as you said, itís doing it with the bike stopped in neutral, itís certainly not your drive chain but it could be the cam timing chain. Iíd check the tensioner...

There are other threads on this problem saying its the muffler. (kind of sounds like an old VW bug?)
Mine does the same thing and has since I got it at 13k miles. My mechanic said its not really a problem, its just annoying.

Yeah I suspected that, but they're both from Brazil, and I related to the supplied video with audio ... From the OP, first impression is also pointing to a deteriorating muffler/catalytic converter unit. I still have my original new and unused one available.

If the bike is stopped and sound is present, best to lift the V up butt first on a stand, rev it and listen closely for this strange sound. Suspect something loose in the exhaust.

Donít frown... Your initial diagnosis was good... Now we just have to find the guy in the video to tell him...
