So I was thinking about getting an actual ATV cover since winter is coming up and mines sitting outside with some plastic over it. What's your opinions on the pros and cons of putting covers on ATV's?

 

Mine also sits out in the winter with the plow on it and ready to push snow and in the summer ready to ride. In the winter I am trying to keep in dry; in the summer I am trying to keep the uv rays from fading the plastic. I have always used a cover, but haven't found a cover that will stand the elements for very long. Doesn't seem like anybody makes a good light-weight cover that will last. Wish someone would design one out of gore-tex.
I use the basic atvlogic black covers from Rocky Mountain atv and figure on going thru aleast two a year.
Out here in Wyoming, the dry climate and the uv will finally destroy them.
If you are asking for damage reason.......I have had no rubbing of body parts or any ill effects from keeping mine covered.

 

Two a year is a bit rough.
I've heard that the condensation build up from them will cause mildew, rust and things of that nature, but you haven't had any of these issues? Anyone else?

 

If you are wasting money buying 2 covers/year why not go out and buy one of those rubbermader plastic sheds that you can use for storing your ATV. You can buy a 6x8 pretty cheap.
