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.

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
