2-Stroke Cylinder Porting for Motocross

In motocross, power isn’t just about peak numbers — it’s about having a strong, usable power band that lets you drive out of corners, clear jumps, and stay in the meat of the power lap after lap. Our cylinder porting service is designed with that in mind.

We don’t just grind away at transfer ducts. Instead, we focus on precision shaping of the port windows where it really counts, refining flow and timing to broaden the engine’s performance curve. The result is smoother low-end, stronger mid-range, and a cleaner pull all the way to the top.

Every cylinder is tuned for motocross use — giving you a bike that’s easier to ride, faster out of the gate, and more forgiving if you miss a shift. It’s about more than just top-end hit; it’s about creating an engine that’s powerful, responsive, and consistent across the entire track.
