Boost throttle response and broaden your 2-stroke powerband with the Boyesen RAD Valve Reed Cage Assembly. This performance reed valve system is engineered to maintain intake flow velocity and redirect the intake charge for more even distribution to the intake ports—helping the engine respond faster and pull harder through the rev range.
Designed as a true bolt-on upgrade, the RAD Valve uses a one-piece aluminum casting that installs easily with no modifications required. The specially designed reed cage holds Boyesen’s patented dual-stage reeds, delivering a clean, crisp hit off the bottom while still supporting strong top-end power. The result is a noticeable improvement in rideability—especially when you want more torque, sharper response out of corners, and stronger acceleration.
