Thanks for all those reply, i really aprreciate it. First i think im gonna removed them , inspect them and buy them OEM or all balls or at a bearing supply shop.
For your question HONDA NG GINGSA, my bike is only 14xxx KM i know it is very low to replaced a wheel bearing. I noticed that i had to change my bearing when I was pumping air in the tire, I noticed a sideplay between the wheel center hub and the swing arm. I lift my bike and took the wheel with both hands and I could move my wheel from left to right not a lot but a small sideplay.
