AELLA Crankcase Internal Pressure Control Valve for Ducati Monster 821 / 1200 / R

During traveling, the inside of the crankcase is pressurized by the high-speed reciprocating motion of the piston. This excessive pressure becomes a large resistance of the piston movement, causing various harmful effects. The internal pressure control valve keeps the crankcase internal pressure proper by merely installing, great reduction of vibration of the engine, great reduction of engine braking which is too strong, and entry into the corner will be great.

You can also experience the improvement of torque as it is smoothly improved at the time of low rotation or as if tuning the engine.

Unlike the conventional breather tower and breather hose interruption type, it is mounted in a hose of the connection part of breather hose and air cleaner box. Just raise the tank, just remove the breather hose from the air cleaner box and fit in, so you can work in a short time.
