† New RC2 design
• BOYESEN engineers embarked on a mission
to create a new lineage of aerodynamic
intake technology by refining the
primary performance factors required
to increase peak horsepower through
design innovation: Aerodynamic Surface
Optimization, Model-Specific Reed Petal
Tensioning, Material Fuel Resistance,
and Multi-Stage Reed Timing. 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
