Exhaust Yasuni C21 Minarelli Horizontal Blue

Yasuni Carrera 21 Aerox

The Yasuni Carrera 21 exhaust system (C21 for short) is a high-end exhaust for 50cc scooters and should be used with a racing cylinder of at least 70cc. Compared to the Yasuni Carrera 20, the C21 has a slightly longer expansion chamber, delivering strong torque and excellent performance in the mid to high RPM range—ideal for powerful acceleration, especially when exiting corners.

Designed for high-revving engines up to 14,000 rpm, the C21 is a top choice for track use, offering rapid acceleration on corners and short straights.

All parts required for installation are included.
