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.

Frequently asked questions
Is the plate included?
No. The KR5121 must be combined with a Monokey (KM5, KM7, KM8A, KM8B, KM9A, KM9B) or Monolock (KM5M, KM6M) plate, purchased separately.
What color is it?
Black, like most Kappa rear racks.
How much weight can I put in the top case?
The maximum load allowed for this rack is 6 kg, including the top case.
Does it also fit the C 650 GT?
No: the GT has a different rear end and requires a dedicated rack. This code is specific to the C 650 Sport.
Can I use a Givi top case?
Yes: Kappa and Givi share the Monokey and Monolock systems. The KR5121 corresponds to the Givi SR5121.
