I pulled the trigger on a pair of Givi V37 side cases for my 2018 Vee XT. They arrived today, so I figured I'd take a few pictures and describe the install process.
Before I begin, I apologize in advance for the quality of the pictures. Raining outside, then got dark quick, so most of them are inside the garage with crappy light. Anyway, onto it...
As I said, I ordered the Givi V37 Side cases. The mounting racks for these are PLXR 3114. On Revzilla, they're listed as Givi V35 Rapid Release Sideframes.
On a side note, OnTrac (delivery company) completely destroyed the box for the mounting racks. I was amazed the racks were still in it. However, they were excessively wrapped in bubblewrap, and were therefore undamaged.
The racks come with different length bolts, and different length metal spacers. Pay attention to which lengths go on which sides:
When attaching the plate mounts, the directions aren't very clear on 2 things: First, that you need to widen the 4 holes so that the metal spacers aren't sitting on top of the plastic. I found it easiest to remove the to plastic pieces (one on each side of the bike) with an allen wrench:
Then drill them out on a block of wood to 12mm diameter (or 1/2 inch).
The second part I found lacking in the directions was which way was the inside / outside of the mounting plates. Never having had cases before, I put them on incorrectly at first. In this picture, you can see the raised part where the pins 'lock-in'. They should be pointing towards the bike, not out.
This picture has them in the correct position. Note the smooth face plate:
