Used Givi TRK52B in the rarer Black colour. In good condition, with some usage marks. I also still have the original box.
I've owned the box for about a year or so & I am now selling it due to selling my bike.
It's a fantastic box that is very useful day to day or on longer trips away. Due to it being a rectangular shape, there is no wasted space when packing the box as you can fill every space. The clever design of a deep lower half and a relatively shallow lid section means there is no guess work as to if the lid will close! You can also get the back rest accessory & the top rack to attach to the box if you need more luggage space.
It will hold a helmet + bike jacket & trousers, so very useful when popping into town or going to work where you don't want to be wearing your gear.
If your bike already has a luggage rack on it, you can easily buy an adapter plate from SW Motec or Givi to make this box fit. The links below will help you find the right one for your specific bike.
Generic Givi plate is about £40 or so
This is over 20% cheaper than a brand new one & still in good condition with the original box. No offers under £150 are being considered at that's what the box is worth at the minimum.
