This post is to describe how I got the reflections on the Vespa in a studio environment. I think you can just add a HDRI to the environment slot in the material editor. But I did it like this.
I created a sphere around the Vespa and applied the HDRI checking it was 2 sided and in the Self-Illumination slot. The Vespa is on a plane with an omni light with a multiplier of 0.01. When it came to rendering I added a Object ID pass and a separate object id to the bike, plane and sphere in the objects properties. The pass and render are below
Using the pass in Photoshop I masked out the background and added a gradient. I hope this all makes sense please feel free to add any comments and ask questions below.
