The Boyesen Rad Valve Reed Cage Assembly is a performance intake upgrade designed to make your 2-stroke engine feel sharper, stronger and more responsive. By maintaining flow velocity through the valve and redirecting the intake charge, it helps achieve a more even distribution to the intake ports—translating into quicker throttle response and improved power delivery where you feel it most.
Built from a durable one-piece aluminum casting, the Rad Valve is designed to bolt in easily with no modifications required. The specially engineered reed cage holds Boyesen’s patented dual-stage reeds, helping deliver crisp low-end response while supporting horsepower across the RPM range—ideal for riders who want stronger torque and a more lively engine character on track or trail.
