Frequently asked questions

Is the original rack needed?
Yes. The KR5129 mounts only if the original plastic rack fitted as standard on the motorcycle is present: it is the base to which the fitting is attached.

Is the plate included?
No. The KR5129 must be combined with a Monokey (KM5, KM7, KM8A, KM8B, KM9A, KM9B) or Monolock (KM5M, KM6M) plate, to be purchased separately.

Is it suitable for the new F 800 GS from 2024?
Yes. The KR5129 covers the F 750 GS and F 850 GS (2018-2023) and the F 800 GS (2024-2025).

Can I use a Givi top case?
Yes: Kappa and Givi share the Monokey and Monolock systems, so the plates and top cases of the two brands are interchangeable.
