The Yasuni Cross ML is a sport exhaust system for two-stroke engines and is suitable for 50 to 70cc sport cylinders. The design of the resonance chamber supports a balanced power delivery in the mid-range RPM range.

For optimal tuning, the use of a carburetor with a 19 to 21 mm bore is recommended. In higher-performance setups, a reinforced clutch may also be useful for reliable power transmission.

The exhaust system is intended for mounting on the left side of the vehicle and is characterized by high-quality workmanship. Thanks to E-approval, the Yasuni Cross ML can be used in public road traffic within the framework of the applicable regulations.
