With a robust sound and improved performance values, the Yasuni Cross ML stands for proven quality. The exhaust develops its full potential, particularly in the medium speed range and is therefore ideal for 50 cc - 70 cc sports cylinders.To get the most out of the Yasuni Cross ML's performance, we recommend using a 19mm - 21mm carburettor. In addition, we recommend a reinforced coupling to prevent the clutch from slipping unintentionally, particularly when starting off.Color: carbonApplication range: 2-strokeModel: Cross MLWith approvalInstallation position: rightAbout the manufacturer YasuniA brand for those who love speed, sound and quality!
