The “R” is the evolution of the “Z”, with more volume and a wider cone, an ideal complement to Sport/MidRace 70cc cylinders. It works very well with 50 or 70cc cylinders, but where it shows its true effectiveness is with 70cc Sport cylinders. For excellent performance, we recommend adjusting the variator setup. With approval certificate. It is equipped with a very high-quality aluminium silencer. Also available in Carbon or Carbon/Kev.
