Roger21 - Tri cities Washington Awesome kit "Great kit really easy to install, I put it on my 07 CRF250R along wth a complete lower end rebuild, and stage 2 hotcam and it rips! Took some of the top end speed out so you’ll need a rear sprocket with less teeth good kit so far and seems high quality"

Jerbo - Santa Rosa, Ca. Awesome "Fun to install and what an incredible change in performance!!!! The sound of the engine is a much deeper tone. Great for someone who doesn't necessarily know alot about engines. Follow the instructions and feel like you own your engine and its capability. It's very enpowering."
