exhaust Polini Big Evolution 94cc for Minarelli AM6

This low-mount Polini Big Evolution exhaust system was specially developed for the Big Evolution cylinder kit to get the last reserves of power out of the engine. Brutal power delivery guaranteed. To withstand the higher compression of such a cylinder, a special exhaust flange with 3-point mounting is used. Therefore, the Big Evolution exhaust systems are only to be used with the corresponding Big Evolution cylinder kit.
