Description

The stock reed valve is your two-stroke's bottleneck. Boyesen's dual-stage reed design eliminates that restriction, delivering measurably higher flow velocity across your entire power band—from crisp throttle response at low RPM to sustained acceleration at redline. If you're serious about extracting every bit of performance from your KX250, a proven reed upgrade is one of the highest-ROI modifications you can make.

Boyesen reeds are engineered through rigorous laboratory flow analysis to outperform standard single-stage designs. You'll feel the difference immediately: snappier bottom-end response and a broader powerband that translates to real lap times on the track or trail.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
