Description

Your engine’s breathing efficiency directly impacts acceleration response and top-end power delivery. The Boyesen Racing Reed optimizes intake flow dynamics across your entire powerband, translating laboratory-proven performance gains into real-world acceleration. If you’re serious about KTM 617 performance, upgrading from restrictive OEM reeds is a foundational tuning step.

Boyesen’s dual-stage reed design permits greater flow velocity under varying operating pressures, eliminating the performance plateau you experience with single-stage reeds. This means sharper throttle response at low RPM and sustained high-end power when you need it most.
