2011 Sportsman 400 body vibration noise

I hear the front and back body and racks and fenders vibrating and making noise when reving the machine up. Everything seems tight. Is this normal? Anyone else notice this? Mine has less than 30 miles on it.

I have the same ATV. I have about 120KM on mine now. I can hear my fenders vibrating too. I think it's normal for the newer bikes with so much plastic on them.

I don't notice it so much riding, just sitting still. I guess no biggie. Thanks!

I don't know about glngib but I really like mind. Can't waiting until the winter is over. To much snow to ride in up here.

This is my first atv. I did have a motorcycle. It is a good beginner machine for me. Glad I have the 4x4 but try not to use it no more than I have too. Had mine about a month now. Been pretty cold here plus working alot to ride it. I have to haul it to ride it. Friend has 180 acres about an hour away and another place that is closer has trails and charges $10 per machine to ride. Bring on the warm weather for sure. Oh, a mecanic at work told me to make sure the muffller is tight and not vibrating.

Don't know what it might be on the new models, but from 05-10, it's common for the back rack to vibrate against the fenders. A little bead of silicon on the bottom of the rack is a quick fix. Might work on yours too if you can find where it's vibrating at.

My 05 500HO vibrates when you rev in neutral and also when you are riding,I've tried to find where it is but haven't yet, I think it is something a person has to live with.Cold weather makes it worst.
