Tutorial SC - New brake caliper mount bgm Vespa PX


Our professional brake caliper mount from bgm PRO Made in Italy: Allows the assembly of the radially mounted BGM PRO 4-piston brake caliper, which enables braking values ​​at motorbike level with fine dosing.

The brake caliper mount is available for Vespa or LML. The difference between the two types lies in the different dimensions of the speedometer drive. The selection of the right adapter therefore depends on the existing/used brake drum (Piaggio or LML).

  • A Vespa PX (1985 model) that was subsequently converted to disc brakes with a Grimeca retrofit kit requires the PX adapter.
  • A Vespa PX (1985 model) that was subsequently converted to disc brakes with an LML fork requires the LML adapter.
  • A Vespa PX Disc (1998 model) requires the adapter type Vespa PX.
