YASUNI Carrera 21 (manufacturer reference: TUB910C) is a high-end exhaust line designed for demanding riders. Designed to be paired with a competition cylinder of at least 70 cc, the Carrera 21 stands out for its mid to high RPM oriented temperament: it offers excellent extension and a pronounced sound, ideal for those seeking responsiveness during acceleration and stability at sustained speeds without unverified numerical promises.

• Brand: YASUNI
• Category: Complete system
• Finish: Carbon finish silencer (model shown)
• Pipe: Steel
• Homologation: CE approved — not approved in Switzerland

The Carrera 21 positions itself as the option for those who want to exploit the upper end of the rev counter while maintaining a healthy behavior in the mid-range. Compared to the Carrera 20, it prioritizes performance at mid and high RPM rather than pure explosiveness at startup. Shown here in carbon, the silencer is also available in black or Carbon-Kevlar finish. Particularly suitable for sporty models like YAMAHA AEROX R, MBK OVETTO, or PGO LIGERO.
