Cylinder Kit ATHENA Power Valve System Ø39,88 Pin Ø12 Derbi/ Piaggio D50B
Article information
The new cylinder kit was designed with a pneumatic valve system to guarantee better engine response and torque at low and medium engine speeds, guaranteeing the user a fluid and high performing ride in every situation or on all racing terrains.
The throttle valve, designed by Athena already used in the cylinder kit for AM engines, operates through a pneumatic system that exploits exhaust gasses to activate the valve.
The pneumatic system is supplied with two different contrast springs that allow the valve's opening to be adjusted.
This makes it possible to avoid the use of an
electronic control unit.
