Pot d'échappement YASUNI Scooter R Aluminium

The "R" is the evolition of the "Z" with more volume and a wider cone, making it the ideal complement for 70cc Sport/Race cylinders. It works well with 50cc and 70cc cylinders but its true efficiency becomes apparent with the 70cc Sport cylinders. For superb performance we recommend modifying the variator application. Yasuni Scooter "R" full exhaust system Improves scooter performance Power gain Requires a modification of the variator development Combines lightness and rigidity With certificate of approval Comes equipped with a good quality aluminium cylinder Exhaust approved for street use
