Anybody know anything about Namura pistons? Anybody running one or have experience with them? They are on eBay and a piston kit is $65....

If you don't crash once in a while, you're not going fast enough.

Actually Namura pistons are manufactured in the same factories and to the same standards as stock pistons. I used to sell 1000's of them every year. We had a ring pin come loose once and rebuilt the customer's engine free of charge to repair the damage.

That was the one and only failure I ever saw.

You also see far fewer cold seizures with a cast piston than a forged.



Empty a bag of skittles into the toilet and then flush. It's like watching a five second long nascar race.

I always go OEM for pistons, rings. Especially on a two stroke.

I have seen one look like a a bunch of rocks it broke up so bad in a 2008 rm 250 2 stroke cheaper is not better I have seen more cast pistons break more than forged . I would prefer to spend alittle more on a stronger part and not have to worry about it
