Technical specifications

Data from the official Kappa K5600NB datasheet and the Kappa Italia 2026 catalog. Kappa does not publish the weight of this top case, which is why we do not include it in the table.

Compatibility

The K5600NB is a universal MONOKEY® system top case: Kappa does not link it to a list of motorcycles, but to the plate. It fits any motorcycle or scooter on which a MONOKEY® plate is installed — Kappa or Givi, the system is the same.

The other finish of the same size

Volume, structure, MONOKEY® attachment, and maximum load are identical: only the color of the cover changes.

Assembly

The top case rests on the MONOKEY® plate and locks with the attachment mechanism; the same security lock key opens the lid and detaches the case. If the motorcycle does not already have a MONOKEY® plate installed, the plate (and possibly the model-specific rack) must be mounted first. Respect the maximum load of 10 kg and the load capacity stated by the motorcycle manufacturer for the rack.

Who is it perfect for

For those who travel in two and want to store two modular helmets in a single top case without carrying them around, and for those who use their motorcycle daily and need a spacious, lockable compartment. The 56 liters and 10 kg load place it in the high-end of technopolymer top cases; the total black finish makes it suitable for both a maxi enduro and an urban scooter.
