The Polini Big Evolution 70ccm exhaust is developed specifically for use with the cylinder kit of the same name and is therefore perfectly matched to this. 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 70ccm cylinder kit .
Note: The exhaust has been given a thin layer of clearcoat by the factory, but to ensure that it does not tarnish, we recommend that you maintain the protective layer on an ongoing basis.
