Pistons: Whose are best?

[barty5]

ok the yz426f gettin rebuilt have to get genuine crank as no one dose after market (sux) anyway now im down to the piston and would mind some feed back choices are wiseco, athena, prox, or genuine anyone got any thoughts or used any ive had wiseco in my cr250 and my jetski but then ive heard some bad rumers

[pete376403]

Genuine Yamaha first, Wiseco next and then whatever you can find that fits

[Motu]

ProX are suposed to be genuine old stock....my ProX looks identical to the real thing.

[scott411]

my choice is genuine first, then pro x,

i have never really liked wesico, just had some bad experiences with two stroke's and customers who don't warm their bikes up, to be honest i have never fitted one to a 4 stroke

I've had no problems with Wiseco myslef, but you know the story, 2 people would have had troubles, probably installed them shitty and then complained.....

What is the price difference in tham all?

[barty5]

price not so much of an issue i can get 25% on genuine but they dont come as complete kit so end up around the same although i can get the athena for around $160 complete kit genuine is $188 plus rings $72 plus what ever the pin is worth less the 25% wiseco is $298

hes putting order for my piston and gasket set theyll be in next friday ive gone for the athena forged piston as it should stronger

[NordieBoy]

ProX are cast and Wiesco are forged (or is it the other way around?)

Wiesco of preference but I've got a 2.5mm OS ProX in the '79 XR250 and it goes fine.

[Motu]

Wiesco are made from ear wax.....Wiseco are forged.

Forged pistons are noisier when cold from piston slap....and I've got a Wiseco with a busted thrust skirt.
