This is a small cone that can be used for performing exercises on your motorcycle to help you maintain and improve your riding skills.  This is a scaled down version of cones like those used for most motorcycle training courses, now you can have your own.  I recommend printing them with a soft TPU (I used a 85A), so that running over them won't cause a crash or destroy your cone.  To help keep them soft and pliable, I printed with 3 walls/layers for the perimeters, 10% infill, with the line infill pattern (concentric should provide more strength, but might make them less flexible.

I only had some “clear” TPU when I printed mine, as you can see in the picture, but using bright colors like red and orange should make it easier to see the cones as you practice.
