I have A GTV300 with only 500km on it.
When i turn the gas en let it go to idle, it makes a rattle sound.
Does someone have A idea what this could be, and if it is A problem?

Probably the variator, have the rollers checked.
However it comes from the transmission group.

It's the rollers and it's normal.

Thank you both for the answer.
I think that the sound is A bit loud. Would DR pulley sliders make less noise?

I think it does this because the driving wheel turns without traction and the rollers slam into the guides, falling into them.

Dr.Pulley sliders wont stop that noise, it will be slightly less. When I ride and see a red light I tend to cut the throttle out and let it just roll, when I do that, it takes a few seconds for the transmission to disengage & there is that sound ever so noticeable. I have sliders on, what Ill say is this sliders help cuz besides pick up etc, they dont engage in the growling seal noise that one gets with rollers.

Confirming it's the rollers!
As the other guys are saying, don't worry about this noise. It's completely normal and is present on most scooters with CVT transmission. Just enjoy the bike. By the way, as the rollers wear the noise can get a little louder. You can notice it on every Vespa bike.

It sounds like the theme tune to Scooby Doo to me.
