Converter nut -BGM PRO- Piaggio Ciao, Bravo, Si, Boxer vehicles with variator

The BGM Variomutter is characterized by its collar that goes about 4mm far into the variomatic, so it is ensured that the entire thread of the crankshaft is used.

The Variomutter was developed for the Polini Speedcontrol and Malossi Multivar.

The width across flats is 22mm. Outside diameter of the collar is ca.10mm.

When using the SC Variomutter, the locking plate is omitted.
We recommend medium strength threadlocker e.g. from Loctite item number: 3600015.

Tightening torque of the Vario nut is 20Nm.

Please do not tighten with an impact wrench!
