ATHENA's R&D department have come up with an innovative new Minarelli AM6 cylinder kit which features a pneumatic 'Power Valve System' to give improved low RPM and top-end performance.
ATHENA's Power Valve System exploits exhaust gas pressure by way of a guillotine valve. At low RPM, when exhaust gas pressure is low, the Power Valve is kept closed by a spring inside the pneumatic system. When RPM increases the pressure of the exhaust gas raises causing the pneumatic system to move the guillotine valve upwards.
The kit also comes with a specially designed aluminum Cast Lite piston with Molycote flat head to eliminate frictions.
Two versions will be available; 50cc and 80cc. We'll keep you posted as soon as they arrive!
