I purchased this quad for my grand daughter about 3 months ago, so far so good. We have a ATV park just a few miles away and it seems to be able to handle the trails ok, except for the low ground clearance.

Anyway I did notice that when she rides it 6 1/2 years old, rides like a board stiff.

So here is what I did, found all the front a arms to tight, better yet I placed grease fitting on all the a arms pivot points, didn't over tighten the bolts when I re installed the a arms.

I also did the same on the rear swing arm, found those bearings kind of dry, I also put one on the rear hub where the rear axle is.

Now it has some movement like I thing it should have.
Seems the take the trails a lot better.

Little bit of work but well worth it.

 

I plan on doing the same to all my quads. got me why no one puts grease fittings in.
