Exhaust Polini Racing Big Evolution 94cc TWD Minarelli Horizontal

Polini Racing & replacement exhaust systems always stand for high-quality workmanship & top performance. The Italian manufacturer tests and develops its systems in its in-house development department, always placing the highest demands on its products.

ATTENTION! The Evolution exhaust system can only be installed if the side stand is removed.

The Big Evolution exhaust systems were specially developed for the Big Evolution cylinder kits to get the last performance reserves out of the engines. To withstand the higher compression of these cylinders, they use a special exhaust flange with 3-point mounting. Therefore, the Big Evolution exhaust systems are only to be used in conjunction with the appropriate Big Evolution cylinder kit. In addition, the included bracket also fits the optionally available Polini Torsen WD additional swingarm. This gives heavily tuned engines the necessary stability by relieving the crankcase.
