Noise from the rear end of out 2017 rzr 4

We took our 2017 xp 4 1k out today for the 1st time with less than one mile on it and notices a weird noise from the rear end when driving below 2800 rpms. sounds like a belt slipping. any idea what it could be? Starting to think its a vibration noise now.

Mine does it too. I consider it normal. I believe it to be belt squeal. The belt and clutch sheaves are breaking in and imo will go away soon. Might be a bit of oxidation on the aluminum from sitting awaiting delivery to you. Non-issue.

I have a 2017 also, about 350 miles on her and she definitely makes that kinda "whining" or "whirring" (best I can describe it..sorry) sound at low speed/RPM. Not sure exactly if it's normal or will ever break in and go away?? Haven't had any problems yet so I'm keeping my fingers crossed.

Does it change in pitch when you tip in and out of the throttle?

It doesn't really change in pitch it just goes away above 3,000 RPM (approximately).

The belts make noise. The plastics vibrate and make a (squeaking/squeal) type noise, the splash shields make noise, the clutches themselves make noise, the engine clicks and ticks, the fuel pump whines and changes pitch based on engine load and battery load.

Lots of drama and ruckus from back there. It's best to just drive fast enough that you can't hear any of it.
