Yasuni R-Pro Black Exhaust Minarelli Horizontal 2-Stroke

The Yasuni R-Pro Black is a high-performance exhaust system developed for scooters equipped with a Minarelli horizontal 2-stroke engine. It is designed to deliver excellent performance with both 50cc and 70cc cast iron or aluminium cylinder kits.

Optimised for operation between 10,000 and 12,000 RPM, the Yasuni R-Pro features a carefully engineered expansion chamber that improves exhaust flow, resulting in strong acceleration, sharp throttle response and power outputs of up to approximately 12 HP, depending on the engine setup.

The lightweight construction improves the overall power-to-weight ratio, while the black silencer gives the exhaust a clean and aggressive appearance. This version is homologated, making it suitable for road use where local regulations permit.
