Description

Part not approved on open road, only reserved for competitions, closed circuits.

The POLINI W aluminum kit is the only 70cc model on the market to have a W-shaped exhaust! Being manufactured at GILARDONI it goes without saying, this W will allow you to have the widest possible exhaust without risking the segment tearing.

This nykasil treated aluminum cylinder has a Ø47mm bore, it is very well finished, it has a revised admission, very worked and corrected like its big brother the POLINI evolution kit. This cylinder being in aluminum, with W exhaust and in single segment has more high speeds than the cast iron models like the POLINI Corsa, thanks to its diagrams lower than the evolution, it will offer you a lot of torque, it is therefore to be classified. between torque and power (nm / hp) compared to the corsa and to the evolution. This cylinder will also be an excellent base for the craziest preparers ...

With an evolution type architecture and a W exhaust, with good preparation, there is plenty of power to come out. The piston installed is a luxury ASSO model with a high silicon content and a single segment, this segment is a hard chrome domed model to allow the highest speeds. The cylinder head has been increased and redesigned like the cylinder for better cooling. The cylinder head is a high compression model with a polished hemispherical chamber.

We will have strongly appreciated that the cylinder head is passed in O-ring (against single aluminum gasket for the origin) this allows much more security on the sealing, the compression of the thermal group. A 0.30mm carbon valve blade is delivered in order to obtain better performance and more solidity with this kit. In short, this POLINI aluminum W kit provides an excellent power / torque and price ratio!

We recommend it with at least : 17.5mm carburetion, racing exhaust, reinforced crankshaft, reinforced bearings.

Cylinder d.47mm alu W

As an option we offer you a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder.
