There are alot of options out there, personally though, I would stay away from the 160bbk on the 125 based engine, as stated,you will go through top ends about every five tanks of fuel.

Why do you think that? Just curious I have one on my bike and havent ran it yet

The key to getting the most out of this kit, is, always keep fresh oil in it, always let it warm up to operating temps before putting it under a load , and when doing the warm up do not rev it alot.



These pitstons do not have enough surface area for lubrication , they also rely on the sides of the piston as well as the minimal skirt for support, so they need to expand completly .

Take the extra time and you will get the most you can out of it.
