Shipping notice: truck drivers' strike in Italy
Updated 19/10/2026
Since 16 October, truck drivers protesting against high diesel prices have been blocking roads and ports in Southern Italy (Campania, Calabria, Sicily, Puglia, Basilicata), and the protest could spread to the rest of the country. The strike affects all our shipments, in Italy and abroad: Poste Italiane is currently not collecting parcels, while BRT and DHL are collecting as usual but deliveries may be delayed in some areas.
- Italy we ship with BRT and DHL · possible delivery delays
- European Union for now we ship with DHL only · possible delays
- Non-EU countries (customs) shipments temporarily suspended: they will leave as soon as Poste Italiane resumes collections
We apologise for any inconvenience and thank you for your patience.

The Kappa K621 is the specific passenger backrest for Kappa K42 and K52 top cases: a black expanded polyurethane backrest that attaches to the top case and provides a back support point for the passenger. It is sold separately: the top case and mounting plate are not included.
✓ Strengths
- Specific, not universal – shaped for Kappa K42 and K52 top cases
- Expanded polyurethane – this is the material Kappa states for its entire range of passenger backrests
- Uniform black – matches the top case without clashing
- Back support – the passenger stops holding on only with their arms
- Original Kappa Moto (Givi S.p.A.), not aftermarket

Who it's perfect for
For those who have a K42 or K52 on their motorcycle and often carry someone. Without a backrest, the passenger travels by gripping, and on a long journey, it's noticeable. With back support, the position changes: you sit, you're not attached. It's also the part you look for when the old one is worn out and the top case is still perfect.
