BOYESEN Rad membrane system - Suzuki RM250

Boyesen engineers have applied a range of technical innovations to their range of intake systems to ensure optimal power, torque and smoothness: Aerodynamic Surface Optimization, Model-Specific Reed Petal Tensioning (specific valve for each model) , Material Fuel Resistance (materials resistant to hydrocarbons) and Multi-Stage Reed Timing (valves that open in stages).
The BOYESEN valve diaphragms have been specially developed for each engine model

• 100% aluminum housing, optimized condition of the inner surface
• 4-way diffuser to optimize flows and prevent discharge
• Intake manifold and mounting clamps included, direct mounting without modification
• Variable flexibility valves specific to each model (aerospace grade carbon)
• Rubber-coated valves that are resistant to hydrocarbons ensure longer gasket life

The RC2 valve diaphragms, developed for competition use, noticeably optimize the intake air flows and thus ensure more efficiency, more power and a better increase in speed of your engine!
