BGM PRO adapter plate - for perfect damper geometry on PK forks with disc brakes
If a Vespa PK fork is fitted with a disc brake system, the position of the upper shock absorber stop changes. The cause: The brake systems used (e.g. on PX models) were not originally designed for the geometry of the PK fork.
The solution: BGM PRO adapter plate. It corrects the position of the upper shock absorber stop and thus ensures a straight, tension-free installation of the shock absorber - without restricting the spring travel or response behavior. In addition, the shock absorber is lowered by approx. 5 mm, which improves the vehicle balance.
Steel instead of compromises
The plate is made of high-strength steel and is supplied powder-coated in black. It is simply fitted in place of the original shock absorber mount - no welding, no milling, no improvisation. Perfect for clean conversions with high suitability for everyday use.
Compatibility
The adapter plate fits all Vespa PK forks if a disc brake system from the PX range is used - for example from:
✔️ Piaggio (PX Disc from 1998)
✔️ Grimeca (Classic and NT)
✔️ BGM PRO disc brake systems
✔️ OttoPuntoUno (8.1) brake systems
✔️ and others
Designed for use with e.g. BGM PRO Competition shock absorbers for Vespa PK
✔️ Advantages at a glance
✔️ Optimizes the shock absorber position for disc brake conversions
✔️ Prevents lean angle and unfavourable load distribution
✔️ Improved front suspension response
✔️ Approx. 5 mm lowering - promotes good balance
✔️ Made of robust steel, powder-coated
✔️ Compatible with all common disc brake systems (PX type)
✔️ No welding or milling necessary - plug and play
FAQ - Frequently asked questions about the BGM PRO adapter plate
Do I have to weld or mill the fork?
No. The adapter plate replaces the original upper shock mount and is simply bolted on.
What effect does the lowering have?
Lowering the fork by approx. 5 mm improves weight distribution and supports more neutral handling.
Which brake systems are compatible?
All standard PX-based disc brake systems: Piaggio, Grimeca, BGM PRO and OttoPuntoUno (8.1).
Which shock absorber is suitable?
All shock absorbers in PK format, harmonizes perfectly with the BGM Pro Competition shock absorber for Vespa PK.
