Kiesler Bearing + Nut (primary shaft) Piaggio NRG / Typhoon

The special nut is screwed onto the primary gear shaft (clutch shaft), replacing the original one. The bearing is placed into the variator cover. The primary gear shaft is now supported at both ends, the stress on the original bearing is reduced. This additional support will reduce vibrations from the torque drive and, as a consequence, reduce stress on gear box cover and primary gear. As a result, your transmission will run more smoothly.
