    In danger of starting another major discussion on this I have a question.
    I have a basic V1K (2022) and it came with a basic rack and a sticker that said no more than 6 kg.  I bought the Kawasaki mount for Givi topbox and fitted it with the new screws that were provided.  I also bought a Givi Trekker 46L topbox.  When I weighed the topbox it is 6kg on its own.

    So my questions are
    1. does the 6 kg limit only apply to the basic rack?
    2. If you bought a V1K with the Givi rack already fitted does it have a different sticker and different weight limit?

    I have the same version of Versys as you but my box is the v47 with a different weight limit. Go with what Givi recommend after fitting the Givi plate. Don't forget you need the Givi plate to mount the box anyway.

    Apologies for the delay in saying thanks for the input.  I was away and somehow cant reply to this on my phone. Anyway, I used the topbox and it was no problem at all.

    I’m in the “load it up to :172:” camp.
    Yes it’s more weight but the bike can handle an adult on the pillion seat leaning back for hours, I doubt a little extra weight in the top box without a pillion is gonna wreck it.

    Now don’t go adding a tonne or anything but I’ve added 15-20kg to that top box before and rode for hours. Didn’t even wobble.

    I think it’s more based on how you ride. Ride like an idiot and the weight will be more of an issue. Ride sensibly and it won’t act like lever so much.
    Kawasaki have to assume people will ride like twats and so put a lower weight sticker on it just in case.
    If they didn’t then some twat would put 50kg into it and assume they are Jonny Rea and wonder why it fell off…

    Common sense and knowing your own limits.

    You guys are packing spare underwear…???

    I've loaded bikes up like Jay has in the past with no problems,  just use common sense.

    Likewise, obviously any weight in a top box will be 'multiplied ' due to the fact that it is overhanging on the rear of the bike

    I've toured Europe with more than the recommendation of load , but not excessive!

    Just keep it sensible,  and as Jay puts it don't ride like a twat.

    BTW Jay is that a spare pair of your undies hanging from the handlebars    :008:

    Thankfully not though. A camo mask that I don’t get to wear a lot in this great country…
    Well I could but it means something different here.  :745:

    Turning this into an engineering problem, there are two basic issues:
    1) the top box is a cantilever off the frame. There's a static weight to make the support break that will be reduced if you go over sharp bumps and inertia kicks in.  This is possible but not very realistic.
    2) the centre of gravity of the top box sits behind the rear spindle so there's a moment arm. As you load the top box you take weight off the front wheel. This is real, no matter how much or little weight is added. Strictly speaking, the box itself takes a tiny amount of weight off the front compared to the basic or LT models.

    The 5kg limit can be taken as pessimistic to cover Kawasaki's behind. If they didn't put a limit on it they could be liable for any crash with stuff in the box. You can undoubtedly exceed it but, as Jay has said, don't take the piss. Two up you have no real alternative place to add luggage but solo you do. Strap stuff to the pillion because its centre of gravity is in front of the rear spindle so you'll add weight onto the front, counteracting any weight on the top box. A pillion does the same, of course, but don't tell Ruth I said her weight's useful as ballast!  :745: :745: :745:
