The new RC2 Series Rad Valve is Performance Optimized - tailor made to give the new 2013-2021 Beta 250cc/300cc engines improved roll-on transition from low to mid, and greatly enhanced mid-range torque. The performance goal for the new Beta engine platform further enhances the smooth and powerful engine performance delivery characteristics that are inherent in the new Beta engines. The RC2 Series Rad Valve multi-stage reed petal system has also been painstakingly developed and tested to increase throttle response and acceleration, while also broadening peak RPM horsepower output.
The Rad Valves seamless, one-piece, precision casting and continuous aero-form surfacing provide maximum flow velocities and instant, explosive movement of air particles the moment you turn the throttle. Standard equipment on each Rad Valve, Boyesen dual-stage model-tensioned carbon reed petals are designed to work specifically in conjunction with the Beta engine characteristic. The race-proven reed petals are integral to the Rad Valves ability to maintain timing with the power pulses of the Beta engine platforms. Your machine will gain maximum flow velocity across the entire RPM range, and at all throttle settings. Smooth. Sharp. Smart.
