The Yasuni R is the upgraded version of the Yasuni Z, featuring a larger expansion chamber for better performance. Designed mainly for 70cc entry-level tuning cylinders, it can also be used on 50cc setups, making it ideal for riders planning future upgrades. It delivers strong midrange power and reaches peak output around 10,000 rpm.

A rubber-mounted stainless steel bracket minimizes vibrations, ensuring durability and stability. The exhaust is road-legal thanks to restrictors in the header and silencer — removing them unlocks full power but voids approval.

Like top-tier racing systems, the spring-mounted silencer prevents leaks and offers an aggressive, sporty sound. The aluminum end silencer is interchangeable and available in various colors to match your scooter’s style.

For best results, pair the Yasuni R with at least a 17.5mm carburetor and a tuned CVT setup.
