Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance.

Im happy with the product although the wrist pin didnt come with the kit. when i opened the box full of parts the piston kit box looked like it was tampered with.
great piston increased horespower and increased engine feel, and not expensive at all
I thought this was going to be a tough job, but found out it was easy. All the parts fit perfect, even the ring gaps were within specs and needed no filing. Bike started right up and is as strong as ever. Great product and will use it again.
We just installed this item on our 08' YZ250F. Everything fit and worked very well. All items were in the box, so no mad dash to the Dealer for missing pieces... Very pleased, will buy again.
overall this is a great kit, the only issue i had was the lower oil seals would not seat, i actually ruined them trying to get them in, they did not need to be ground for proper fitment, just did not want to seat in the piston, i had to spend an additional fifty dollars on new ones but next time ill know to take a little more time seating them. other than that everything in the kit was flawless
after my 2001 yz 80 was rebuilt with the pro lite piston i noticed the bike had a different feel when runnin but the power was outstanding recomend to any 2 stroker
I bought this when I smoked the top end in my cr125, went in like a charm, runs excellent! This won't dissapoint you.
put this in my kx 125 and fit perfect gained alot of power and speed specially in powerband. get this if your looking for more out of your bike
This is a good piston, the circlips are really heavy duty, making it a little harder than normal to get them in.
The piston alone, out of the box looks badass, has black side skirts and deep curves.
It didnt give me any problems going in the cylinder, and once it was in the motor loved to rev.. It requires 93 octane, or it will tick and not work as well. As far as riding, i find myself running through the gears alot quicker, and flying.
My 4 year old battery didnt want to turn the motor at first becuase of the higher compression, so i had to get a new one. Bike sounds real crisp though.
I DO reccomend this piston to anybody running a 4 stroke.
installed this on my cr125 ran it and then rode it..great power and woke up my bike like crazy...puled the front tire on a 125 in 1-3rd gear without trying...however i messed something up im assuming the ring gap was not corret and after about anout 1.5hr ride time the ring caused scoreing on my jug destroying it.
it takes a while to put in but once its in it is really powerful and works way better than any other piston out there
Piston looks trick, and kit seemed complete. I don't like exchanging or going back and getting correct parts. The kit I bought came with the wrong piston pin unless they intended to have clearances that can be measured with a ruler. I had to put back in the used stock pin that was not in ideal condition. Next time I'm buying a different kit.
Big difference in low end torque, runs on pump gas and is made in the USA, what more could you ask for!!!
great product, gave my bike more power over the stock piston. easy to installe and kicked over first time
wiseco quality non the less. great piston, wished it came with 2 ring deisgn instead of the one ring, but love the piston.
The Pro-lite piston works really well in my 450r. It helped out pretty well on getting out the hole.

B) If your bike has stock bore than this piston will fit.
