Yasuni R4 exhaust AM6

The Yasuni R4 is a high-performance exhaust system built for heavily tuned engines with increased displacement in the 84–95cc range.

Yasuni R4 performance

A precision-welded expansion chamber paired with the updated 2025 Max Pro aluminium silencer delivers a clean, uncompromising racing look. Volume and shape are designed for maximum output in the mid to high rev range, with a wide powerband. In practice, that means strong torque kicks in at mid RPM and stays solid all the way up.

The system can be easily combined with most 84cc - 94cc racing cylinders available on the market.

Due to the larger volume and the strong performance, we recommend that you use a larger carburetor such as the PWK 30, a big valve reed valve and a reinforced clutch to prevent clutch slip.

Specifications Yasuni R4 high-end racing exhaust

Suitable for 50cc motorcycles with Minarelli AM6 engine such as Rieju MRT, Beta RR, Sherco SM 50 etc.
