Having done this, there are a number of combinations.
Top Box : FZ447 (Kappa KZ447). This can be installed on it's own.
For the side racks, there are two choices
PL447 (Kappa KL447): these are to use the standard Monokey sidecases.
PLX447 (Kappa KLX447): these are to use the V35 sidecases.
You will not need the PLX447K adapter kit, as this provides the linkage under the passenger rails for the side racks. This is provided by the FZ447.
You can check the Canadian GIVI side (www.givi.ca
), and it has a configuration utility under "For your motorcycle".
In my case, I bought the top rack last year a week after I purchased the bike to use the Kappa K35 top box I kept from my KLR.
It was nice, but there were times I could have used waterproof, lockable side cases, so I purchased a V35 set used over the winter and installed them this past spring.
Just the racks:
Note 1: if you have the option to buy Kappa hardware, it is interchangeable with any/all of the Givi hardware. I have a KL447 rack for the top case, and a PLX447 side rack for my V35 bags.
Note 2: The OEM side racks from Kawasaki will NOT work with the Givi top rack. I have one sitting on the floor of my garage (I bought the bags used, and it came with them), and I couldn't make it work. Spent the $$$ for the PLX447 kit, and it went together easily.
