Crankshaft, connecting POLINI BIG EVO connecting rod long 85mm axis Ø12mm scooter MINARELLI Horizontal (nitro, aerox ...)

Crankshaft with 85mm rod lengthened in relation to the origin of 5mm! Mounts in combination with a normal BIG EVO race kit or another 12mm piston pin kit with a 5mm wedge! The 85mm long connecting rod reduces the forcings and releases the power, especially at high regimes! It removes the thermal group of 5mm of the admission, this increases the dead volumes (ideal on a big diameter kit 47,6mm after example) and this avoids that the turbulence of the valves come to disrupt the admission of the cylinder. This crankshaft manufactured in Italy is of very high quality, it has a machined rod mass, solid masses and a dynamic balancing. Delivered with a high range dimmer nut for a good hold!
