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!!

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

A: Yes. The website runs through the data base of part numbers and finds only parts that are specifically made to fit your bike. If it says it will not fit, then it will not fit. If the part says "Exact Fit" then that part is for your bike.

A: You are correct, Wiseco does not make a piston kit for your bike. Below is a link to your OEM parts fiche where you can find all the necessary parts to create your own.
