  • Cylinder Works Standard Bore High Compression Replacement Vertex Piston Kit

    Cylinder Works Standard Bore High Compression Replacement Vertex Piston Kit

    Davin in Minnesota

    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.

    Smooth and easy install and could tell that the larger piston produced a HUGE power increase! Solid performance and the break in went well.

    Cylinder Works Big Bore Replacement Top End Gasket Kit

    Garrett in PA

    These gaskets are solid.

    The metal gaskets that cylinder works provide with the big bore kit are very good quality. I had to replace my head gasket due to overheating and blowing it, but with as hot as my bike was running, I'm glad the gasket blew before anything else did!!
