Together, these innovations create a new technological benchmark in intake performance. • Boyesen Engineering would like to introduce the all-new RC2 Series Rad Valve, designed to increase overall horsepower and throttle response in the Yamaha YZ250/250X KTM65SX and Kawasaki KX85/100 • Each Boyesen RAD Valve is unique - tailor made to that model, year and displacement. • The intake charge is redirected for more even distribution to the intake ports • Constant flow velocity is maintained for instant throttle response and more horsepower • One piece design and Easy installation RAD VALVE RC2 59-7794 Boyesen's New Rad Valve Reeds are a game-changer, allowing Beta riders with 250cc, 300cc, RR, RX and X-Trainers to fine-tune their power output in three distinct ways. With these three different Reeds - Sprint, Torque & Broad Spectrum Power, riders can fine-tune their power characteristics to match their specific needs, preference or riding style. You can now choose from three power delivery options with one cage by taking your Standard Boyesen Rad Valve intake (Broad Spectrum Power) and change Reed Petals to conquer any riding terrain. Giving you the ability to custom-tailor your bike’s power without breaking your bank account three options one cage. STANDARD - Unleash the Mid-Range Power with Boyesen’s Broad Spectrum Rad Valve performance intake system, the perfect upgrade for your 2 stroke. If you crave sharper throttle response, added torque, increased horsepower in all ranges this is your ultimate choice. BROAD SPECTRUM is meticulously designed to optimize and improve all-around power and performance for all terrains, the perfect bolt-on Power Boost. * TORQUE Reeds - Unleash the low-end power your bike deserves and experience a ride like never before. If you crave punchy and responsive low-end power and want to gain a setup advantage for Hard Enduro, or tight and technical terrain this is your ultimate choice. TORQUE is meticulously designed to optimize airflow at low RPMs, accentuating low-end power delivery. Dual Stage, Carbon Tech frequency matched carbon reeds are engineered for rapid power transfer and maximum flow efficiency at low RPMs. Go ahead... run third gear everywhere. You can do it with a Rad Valve Torque Variation setup. ** SPRINT Reeds - Unleash the top-end power your bike deserves and experience a ride like never before. If you crave exhilarating top-end power and want to dominate the competition in sprint enduros, GNCC, or wide-open terrain the SPRINT is your ultimate choice. SPRINT is meticulously designed to optimize airflow at high RPMs, accentuating top-end power delivery. Dual Stage, Carbon Tech High-Frequency carbon reeds are engineered for rapid power transfer and maximum flow efficiency at high RPMs. Footnotes at bottom of page: # = RAD Valve for Oil Injected Models †= New RC2 design Replacement One-piece clamp 59-7870 $12.95 Torque Sprint NEW for BETA INTAKE / FUEL SYSTEMS
