2015 RMZ 250 WISECO TOP END

I've had the wiseco top end kit on my bike now for a little over 15 hours. There is plenty of power and it doesn't seem to be going anywhere! I would definitely recommend this product to anyone!!

Didn't send enough rings for the piston.

I just bought this piston and it came with one less ring than needed. Now I can't install it with out getting new ones. .

As expected Wiseco put all of the power back into my bike with the aftermarket look. The piston looked so good i almost didnt want to put it in the motor. I have a couple hard rides and havent had the the first problem

Excellent replacement

Wiseco has never failed me yet, and this piston is no different. It looks excellent and the machining is top-notch. Killer upgrade for any stock bike, or replacement for a toasted piston.

Wiseco Pro-Lite Piston Kit

What else is there to say...Wiseco puts out the best pistons, producing the power required when you snap the throttle, nothing else compares!!!

Everything you should expect

Purchased a Wiseco top end kit for my 06' CRF250r. The kit is everything you should expect from a top end company like Wiseco. High compression piston made a huge power difference. Installation was easy for a mechanic. would not recommend a beginner/shade tree to attempt, but if you do...please open your book and follow the instructions. And of course customer service/shipping etc. was everything you should expect from a top notch company like motosport.com. Would have no problem recommending both product and company to any friend!!

Easy Install

This was the first top end rebuild that I have done on any engine and it was surprisingly easy, with a little help from youtube, just make sure you get your timing right

Great piston!

I bought it for my 2011 kx450f and oh man this thing gives you're bike soo much more power! The Top end is way longer now and it added so much more bottom end power! Love it glad I bought it! Deffinatly worth the price. It went together perfect with no problems!

First time for me

I've never replaced a piston before in a four stroke. But, with the economy the way it is I thought I would give it a try. Changing the piston is pretty simple but you have to take a lot of items off the bike to access the piston.

I found this Wiseco top-end kit worked great for my KX250F. Everything worked perfectly including the gaskets and rings. I've put 50 hours on my bike since the piston replacement and it is running great!

Great kit!

I bought this for a 2007 CRF250R, installed as easy as a 4 stroke topend can be to install. Parts fit perfect and really woke the bike up! With the original topend still in the bike I didn't realize how much power I had lost until I put this kit in and WOW what a difference! Power gains from the very bottom all the way to the very top of the RPM range!
