UNCORKED: KX250 PRO CIRCUIT BUILD I f you want to get more out of the KX250, Pro Circuit, which managed Kawasaki's 250cc SuperMotocross race team, offers a custom- er performance package you'll be interested in. They probably know more about improving the KX250 than anyone. We got to try it. The build includes a high-compression pis- ton, a TwinAir Power Flow kit (which features a vented side panel), a full Ti-6 exhaust system, and a rear-suspension link. They also recali- brate the bike's ECU to work with the engine updates. PC claims this is their best bang-for- the-buck bolt-on system for the late-generation KX250 that doesn't require open-heart surgery. On track, the modified bike is everything I wanted from the stock KX—more snap and more overall power. It's amazing what better airflow in and out of the engine can do. Every- thing from the initial roll-on to the mid-range pull, all the way through to the red line, was noticeably improved or increased. More pull, more rev, more fun. The PC-modified engine is freer revving, which, in turn, makes the chassis feel less bound up. Pair that with the longer link in the rear, and the handling down the hills seemed more predictable and less pitchy. For 2025 and 2026 Kawasaki KX250 riders looking to upgrade, we can vouch that PC's performance package can elevate the stock KX to the next level. Ryan Nitzen The PC engine mods include a high-compression piston, improved airflow, and a full titanium exhaust system. For those seeking more from the KX250, Pro Circuit offers an easy-to-install performance package that it claims delivers the best value for your money.
