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.
