NOPE. THEY HAVE BEEN AROUND FOR A WHILE THOUGH. I BELEIVE THEY ARE CAST LIKE STOCKERS . THEY USED TO MAKE A SET LIKE THE VITO SUPER STOCKS ONLY CAST INSTEAD OF FORGED. I NEVER CAME ACROSS ANYONE THAT HAS RUN THEM. WHEN IT COMES TO PISTONS WEISCO FOR FORGED OR PRO X FOR CAST. I WOULD NOT TAKE THE CHANCE WITH ANYTHING ELSE. KEEP US INFORMED WEATHER YOU DIG THEM OR NOT

Hello,

 

I experimented with them about 5 years ago. They're a copy-cat version of Vito's super stock pistons. The only difference is they are cast.

 

The Namura pistons turned out to be a total BUST. Literally! One customer of mine tried them and the exhaust port side broke off and ruined his top-end.

 

I ran them in two different bikes and within a few days the intake bridges were cracked.

 

They might be "okay" on a bone stock engine, but I wouldn't take any chances.

i have been runnin them in my 2 banshees for 2 years now.both engines are ported and piped.i have had no problems with them. its all in who does a good bore job and making sure your rings and pistons are fitted properly.like i said 2 years and no problems.i have not even seen a drop in compression readings yet.but i dont hold my shee wide open for 30 seconds at a time either.but i do run em hard.i do all trail riding.so for drag racing in the dunes or runnin wide open all the time,i cant give any feedback there.

It is Namura, not Numara. A friend of mine use them on his Banshee and he told that they are forged too and have a better price than Wisecco.

ive had them in my banshee for two years now and they run great mine are 80'over and the bike is running a motofast 2into1 pipe and i have no complaints i would use them again no question!all i do is trail ride but run them hard.

What size where the wiseco's you took out, and what size are the namura's that you put back in?
