Polini Evolution 3 70cc Minarelli horizontal Exhaust

Polini Evolution 3 exhaust for Minarelli Horizontal.

Polini Motori brings us a racing exhaust called "Evolution 3", developed to maximize the potential of Minarelli Horizontal water-cooled engines.

It is designed for Racing type cylinders of 70cc and 47.60 mm diameter, increasing engine performance, both in acceleration and top speed.

The manifold connects to the silencer pipe to achieve a Venturi effect that increases gas evacuation, for greater power, reaching 14,000 rpm.

The silencer curve is removable, allowing the insertion of joints of different diameters for an increase in engine rpm.

The nozzle is connected to the manifold by two springs and to the cylinder through two holes that ensure a tight seal.

The silencer is made of black anodized aluminum, elongated to reduce noise, with a larger inner diameter to improve acceleration.

This is a handcrafted exhaust made entirely by hand, giving each exhaust a unique finish.

It features a removable cap for proper silencer maintenance.

It is compatible with the Torsen WD.

Note: includes all elements for correct installation.
