YASUNI TUB307R : YASUNI Scooter R Full Exhaust System - Steel/Aluminium Red

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.

• With certificate of approval


• Comes equipped with a good quality aluminium cylinder


• 70cc cylinder, only for race use
