Description
If you’re running a Honda 631 two-stroke, your reed valve is the gatekeeper to performance—and a stock reed won’t cut it if you’re serious about acceleration and top-end power. The Boyesen Racing Reed replaces the factory limitation with laboratory-proven dual-stage design that unlocks flow velocity across your entire operating range, from crisp low-end throttle response to maximum RPM. You’ll feel the difference from the first twist of the throttle.
Boyesen’s engineering delivers measurable gains where it matters: faster spool-up on acceleration, cleaner power delivery, and the kind of responsiveness that separates competitive machines from the rest.
