in corners even in low speeds it feels like the rear tire is sliping, like i'm about to do a burnout drifting but in really low speed.

 

Have you checked pressure? You also might have gotten into some slime or chicken **** on the road, I've experienced the latter almost crashing my ***...

 

Check your rubber motor mounts.

 

.. and your spokes if you have them.. .also your swing-arm bearings.. as well as your axle adjusters.. start with tire pressure first as LFE mentioned.

 

Yep... and also check the wheel bearings...

 

Welcome to the forum.

 

One more thing - make sure your seat is properly installed. The metal prong up under your tank and the screw tightened in the back. A wiggly seat will make it feel like the tires are falling off.

 

This happened to me once, thought my rear end was sliding around, turns out I just forgot to put my seat screw back in......
