Pistons for 125

[desmond197]

Which are the best brand of pistons for a 125 6 day Sachs motor?  I have Wisco, Mahle and Kolben pistons. I was wondering what  pistons were the best quality so I can put the best one in my race bike and put the lesser quality ones in my trail bikes.
Thanks

I prefer Mahle over the others.  I have never had problems with the others but Like the construction of Mahle. I think the secret is in the boring process and proper piston to cylinder clearance as per piston manufacturer.  Some pistons expand faster than others, thus seizure if too tight of bore.  I stick with .003 on everything I have bored with great results.  Just me!
