Here are some pics and notes on installing the new Givi SR770 Monokey Tailrack, which allows mounting of all the Givi Monokey topcases to the Spyder.
Here's the kit
Four holes have to be drilled in the stock tailpiece with a 3/8 drill and then enlarged to oval shape with a Dremel tool. Probably the touchiest part of the installation
Taillights should not be removed prior to installing the lower frame supports as the rearmost taillight screws cannot be replaced once brackets are mounted.
Keep the Dremel handy, as after replacing the plastic tailpiece minor adjustment of holes may be needed.
don't worry about the holes being slightly oversize as they will be covered by the upper mounting brackets once installed. I believe I'd fill the area around the holes in the plastic tailpiece with some clear silicone to keep water out of the tail, though I doubt the area is waterproof anyway, and all electrical connections are waterproof already.
Finished product (The Moto Guzzi Norge sport tourer in the background is the donor for the topcase in the pictures)
Givi 52L Maxia case mounted. The R300 optional color perfectly matches Spyder, Guzzi, and Ducati red!!
The Maxia will fit two full face helmets. Optional light kit, metal toprack, padded backrest can be mounted to case at extra cost. They can be moved from vehicle to vehicle with the twist of a key and the push of a button.
