Yasuni Motorbike exhaust PEUGEOT 103 SP [50] / PEUGEOT 103 RCX [50]

Exhaust System Yasuni Aluminium Sport - Classic style, refined performance

The exhaust system Yasuni Sport has been specially designed for the iconic mopeds Peugeot 103 SP and 103 RCX. A lightweight design, racing-inspired construction, and a stylish aluminium silencer provide a strong character, backed by a finely balanced performance curve suited for the road.

Configured for 50 cc and 70 cc sport engines, this exhaust system is optimized for what riders actually use the most: from start to mid-range. The result: a quicker throttle response, sharper acceleration, and a higher top speed, all without modifying your engine or adjusting the carburettor.

Rather than requiring aggressive preparation or complex setups, the Yasuni uses optimized exhaust flow, a progressive expansion volume, and smart pressure dynamics to give your moped more punch and higher top speed right out of the box.
