Overview

The Boyesen RAD-01J is a reed cage assembly designed to optimize intake charge distribution for improved engine performance. Constructed from a one-piece aluminum casting, it bolts in easily without requiring modifications.

The RAD-01J is known for providing quicker, sharper throttle response and increased horsepower across the entire RPM range. It also delivers more torque, which enhances performance during uphill climbs, cornering, and over challenging jumps. The specially designed reed cage houses Boyesen's patented dual-stage reeds, contributing to its overall effectiveness.
