Exhaust Polini racing Evolution 70cc TWD

Polini Racing & replacement exhaust systems are always manufactured for top quality and performance. The Italian manufacturer tests and develops its systems in its own development department and demands the highest standards from its products. Caution! The Evolution exhaust system can only be mounted if the side stand is removed. The supplied bracket also fits onto the optional Polini Torsen WD swingarm. This gives the necessary stability with highly tuned engines by relieving the load on the crankcase.
