Rear wheel hub gearbox housing MALOSSI Piaggio Boss, Bravo, Ciao, Grillo, Sì, Superbravo

The enclosure surface is finished with a durable, textured black coating that provides corrosion protection.
It comes complete with high-quality bearings: inner bearing wheel axle 15x21x12mm, drive bearing wheel axle 20x26x12mm, inner bearing primary shaft 9x13x12mm, outer bearing primary shaft 13x19x12mm, gearbox bearing 9x13x12mm as well as FKM oil seals, screws and washers to ensure precise and reliable assembly.

An integrated oil breather with internal labyrinth and external connection ensures optimum lubrication and ventilation conditions. The housing is coupled using five fastening screws and two centering bushes, while the hub fastening screws (M10 x 18) ensure a secure connection.

We recommend silicone paste (e.g. LOCTITE® SI 5926) for sealing, which eliminates the need for classic seals, further increasing rigidity and reliability.
Attention: Operation in pure bicycle motor mode is not possible with this housing.
