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.

Easy to do

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.

Excellent kit, very reliable

Once i replaced my stock ktm piston, and put in this wiseco kit, my engine ran so much better! i could feel the power difference, as my bike needed a rebuild anyway, i went for something that wouldnt break the bank, And i sure did make a great choice!

Perfect for Broad Power

This product was simply an easy pick for the project I had come upon, I was extremely impressed with the performance and strength this product can withstand. I recommend this kit to anybody, and for the fact that MotoSport makes this a forged piston impresses me as well. I found everything I needed and the installation was no waste of time. To all the people out there rebuilding there toys, I recommend Motosports forged pistion kits for any project in process.

Everything you need.

We installed this in my sons 98 CR125. First off all the parts needed are in this kit. After installation it has tons more mid-range power and is overall better running, I guess it was long overdue, He bought the bike used and we had no idea of previous maintenance but it made it run much better.

Cr125 rebuild

I blew my top end on my 2002 Honda cr125r on a Sunday. Took it apart and order this kit on Tuesday night with the 2-day shipping. It was scheduled to be here that friday. It came a day early! Which was awesome! The installation was super easy and fast. I had a blown top end on a sunday and by mid week I had my bike running and was able to go ride that Saturday! I couldn't be more happy! Keep up the great work guys!

Installed on a "B" Cylinder (2004 YZ250)

Good quality products from Wiseco. Installed STD size Pro-Lite piston, rings & small end bearing. Came with all the gaskets I needed. Cylinder was marked as a "B" size (Printed in Ink right above the intake/reed cage) Could still see swirl marks. End gap on the rings was just within spec (on the tight side). Have two full days of riding on it now. Ran the pre-mix a bit rich for brake-in. By the feeling of my boot, there's a lot more compression. Bike will wheelie in every gear. No more tapping sound from the small-end bearing. Can't wait to get back on the bike. Age: 43, Weight 170 lbs. Last bike was a 1986 CanAm 500 ASE.
