In terms of performance, the Yasuni R lies between The Yasuni Z and the Yasuni C16. Ideally suited for 50cc and 70cc sports and racing cylinders. The Yasuni R improves accleration and top speed whilst allowing you to keep your bike street-legal.
Silencer color options Aluminum, Black, and Red
In order to run this exhaust, you need to increase the main jet size and use lighter rollers.
To exploit its full potential, we recommend combining it with a racing clutch (stiffer springs) and a variator.
