put it in my kx125 04 and it seized up and burnt the ring to a crisp. all measurements were on point, it was broken in, oil holes were pre drilled not sure what happened but it ruined the piston and the new nikasil cylinder. it does come with bearing and all gaskets for topened. i would not purchase if i have a exhaust bridge in the cylinder.

Installation was easy, all parts and gaskets came in the kit. Good quality made gaskets. The pro lite piston kit bumped up my compression a tiny bit. And while swapping out reeds i was able to check how the wiseco pro lite piston kit is doing, and it looked perfect after the first track day. About 1 hr on the new top end so far.
Cant go wrong with a wiseco forged piston, and the dual rings is a plus instead of the single racer ring.
10/10 in all aspects
Excellent quality as expected. Wouldn't expect anything less.
The kit came in fast, and it was all packaged great! Everything went together smooth and fit perfect I couldn't of asked for a better product. The power my bike has now is remarkable! I am definitely buying this kit
This was the first time I've ever changed the top end of a bike before but I knew enough to go with the Wiseco kit. The shipping was fast and free and the packaging was extremely organized, all the parts were unharmed! The first thing you'll notice is how pretty your piston lookes and how strong it feels, second you'll notice how light that sucker is and how strong all the parts look. Everything bolted and slipped right in and I had the entire bike back together and started first kick in about 45 minutes. (remember this is my first ever top end change) Immediately after starting your bike your going to notice a little bit of a sound difference, or at least I did. The bike is going to sound like a lean mean torquing 2-Stroke machine and the preformance is nothing but the same! This kit brought much or my torque back and make the bike run better than brand new! I would be dumbfounded if I heard someone did not buy the Wiseco kit. Too bad I forgot to take pictures to upload in this review because you got to see how sweet this kit looks!
Have had great success with these pistons. Have used them on 125's, 85's, 80's, and 65's. Never an issue. motorsport.com is what works best for me. Quick shipping, ease of ordering on there website is the best.
I just threw this booger on my newly aquired and abused RM125. The freshened top end woke it right up, idles and revs smoother and fit perfectly. I wreckon I'll be buying this one again.
Please see attached picture of my piston
Nice kit for sure. Comes with everything you need and quality is top notch.
Nice and easy to use can't ask for more than that.
Excellent product easy to install works like brand new again not to mention the fast and reliable shipping this place is the best will buy all my parts from here on out
Great kit my kx125 is runnin better than ever
This piston is great for your rider with just the swap from oem to the wiseco piston you or your rider will be ripping more competitively than ever. I got it for my 2008 kawasaki kx65 and i'm 17 and the bike still have so much bottom end with this piston its great.
Thanks to wisco my bike is running better then ever before and motosport service was great recommend this to everyone
Easy to install, great quality for a great price.
I've been using these kits for years and never had any problems.
I installed this on my 2003 kx250 and i am very inpressed with it.
This kit has everything you need for a top end rebuild. I've used many Wiseco pistons over the years and never had any problems.
This is the first time I put a new top end on my 2015 yz125. This was so easy to install. It took me about 2and one half hours. That seems like a lot but not that much for a first timer like me.
Wiseco Pro-Lite Piston Kit had everything you need to replace your top end.
Feel free to give me a call
