Its dedicated electronic management interface allows riders to adjust the original exhaust valve without replacing the existing mechanical components.\u003c\/p\u003e\n\u003cp\u003eThe system provides \u003cstrong\u003efive selectable valve positions\u003c\/strong\u003e, ranging from fully closed to fully open, with three intermediate settings. This allows the rider to progressively adjust exhaust sound characteristics and valve behaviour according to their preferred configuration.\u003c\/p\u003e\n\u003cp\u003eControl is provided through a compact handlebar-mounted switch panel featuring two buttons. Pressing the green button opens the exhaust valve by one step, while pressing the red button closes it by one step. Holding either button for two seconds moves the valve directly to its corresponding fully open or fully closed position.\u003c\/p\u003e\n\u003cp\u003eBoth Aprilia applications feature a \u003cstrong\u003ebuilt-in ESE (Exhaust Servo Eliminator)\u003c\/strong\u003e and motorcycle-specific wiring for integration with the supported factory exhaust valve
