VENTIL za ORIGINAL GLAVO

INCREASED 4 STROKE VALVES

FOR ORIGINAL HEAD

After the great success of 560cc bi-cylinder together with Double Power Cam, head valves could not miss!

Malossi technicians have worked to achieve even better performance.

These new valves have a bigger diameter and excellent materials and they are completely re-profiled in order to reach the best performance at all revolutions.

These valves are perfectly interchangeable with the original ones, but it is necessary to slightly adjust head and pistons in order to achieve a better performance (as explained in details in the relevant instructions).
