BGM PRO conversion steering column - disc brake for Vespa Smallframe

Modern handling for classic Smallframe models: The BGM PRO conversion steering column makes your Vespa V50, PV125, ET3 or Smallframe Motovespa fit for retrofitting a disc brake - without compromising on style, but with a significant increase in safety.

Why convert?

With more powerful engines with more than 30 hp, the original drum brake is quickly overwhelmed. This fork solution takes your chassis to a new level:

Modern fork technology: more reserves for braking and handling

No bottoming out: better damping during hard braking maneuvers

✅ Disc brake compatible: For all GRIMECA 20 mm brake systems

Unobtrusive conversion: visually classic, technically modern

Plug and play: Fits without modifications to the frame

Technology & installation

The conversion steering column combines the classic head tube connection of a V50 with the modern swingarm technology of the PK series. It is supplied ready to fit including swingarm. Shock absorber mount, steering stop and steerer tube are adapted - ideal for vintage models, without welding or milling the frame.

Important note on fitting

Depending on the model, the mount for the mudguard must be adapted or replaced with a custom mudguard - e.g. from PLC Corse or TOMAS Compositi.

Perfect setup - recommendation from the SC team

Adapter plate shock absorber mount (item no. 7674326) for exact alignment

BGM PRO shock absorber (item no. BGM7783NB) - length and damping perfectly matched to the PK fork
