The Polini Big Evolution 84 / 94ccm exhaust is designed for use with the cylinder kits of the same name and is therefore tuned to these. The exhaust is of course with 3-bolt clamping at the flange, the silencer black on which is Polini Big Evolution, so your competitors are in no doubt about what you are up to. The exhaust suspension itself is also made of aluminum and is equipped with rubber bushings to reduce the vibrations from the engine. NOTE: Can only be used with the Polini Big Evolution 84 / 94ccm cylinder kits.
Note: The exhaust has been given a thin layer of clear lacquer from the factory, but to ensure that it does not tarnish, we recommend that you regularly maintain the protective layer yourself.
