    Cylinder Works Standard Bore High Compression Replacement Vertex Piston Kit

    Try it!

    I put one of these in my buddy's 2006 CRF250R and wow what a change! His bike's engine was transformed. Although it was knocking on 91 octane. I believe it worked on 93 octane, but we switched to 110 shortly after install. After the success in his bike I decided to get one for my 2012 CRF250R when it was time for a new piston. I was skeptical as stock compression was 13:1 and this Vertex piston is 14:1. Im here to say these pistons really do make a huge difference. After the install I was very impressed with the power delivery. Feels a lot stronger all through the RPMs. Im not sure if 91 octane will work, I run 110. I have a loudmouth intake, stage 1 cam, CRFs only tune, and a Yoshimura exhaust to compliment this piston, It all works extremely well together. Piston even made my bike sound meaner. My brother is a KTM fan, he likes my engine better. His ideal bike would be the CRF engine with this Vertex piston in his KTM frame. I will continue to buy these pistons. It came with Cometic gaskets, which are also top of the line.

    Excellent Products

    Everything that this company makes is high quality made in Japan stuff and are more affordable than the hyped up companies outsourcing production to China. I have bought all kinds of engine parts from them(rods, valves, pistons, cam chains etc...) and never had one of those parts fail on me.
