Yasuni “R” is an evolution of “Z”, with a more important volume and a broader cone, an ideal complement for the Sport cylinders/MidRace of 70 cc. It functions perfectly with the cylinders of 50 or 70 cc, but it is on the Sport cylinders of 70 cc that it expresses truly all its potential. For a better output, it is advised to modify the development of the variator. Delivered with certificate of homologation. It is equipped with an aluminum silencer of excellent quality.
