YASUNI "R" Full Exhaust System

The “R” is the evolution of the “Z”, with more volume and a wider cone, making it the ideal complement for 70 cc Sport / MidRace cylinders.

It works very well with 50 or 70 cc cylinders, but its ok efficiency becomes apparent with 70 cc Sports cylinders. For superb performance, we recommend modifying the variator application.

It comes equipped with a good-quality aluminium silencer.
