The Yasuni R sits between the Yasuni Z and Yasuni C16 in terms of performance, offering an excellent all-round power delivery across a wide RPM range. It is perfectly suited for 50cc and 70cc sport, mid-race, and racing cylinders, making it the top choice for 70cc tuning enthusiasts.

To minimize vibrations, the stainless steel mount is equipped with double rubber bushings, ensuring stability and long-lasting performance.

For street-legal use, the Yasuni R comes with restrictors in both the headpipe and silencer. When paired with an original cylinder, it delivers performance similar to the stock exhaust but with a deeper, throaty tone. Removing the restrictors unlocks the full potential of the exhaust but voids road approval.

Summary :

The Yasuni R offers a wide power band, quiet operation, and a rich, throaty sound. The silencer is replaceable, allowing visual customization to match your scooter. Like premium racing exhausts, the muffler is spring-mounted, virtually eliminating leaks.

For optimal performance, it is recommended to use a minimum 17.5mm carburetor and a tuning CVT.
