Asteroid slalom was a sport in which competitors piloted vehicles across the surface of small asteroids in order to use them as springboards for making high-speed turns and performing eye-catching stunts. During the early reign of the Galactic Empire, the sport saw a period of increased popularity. This prompted the Verpine vehicle manufacturer Roche Machines to produce the V-4 series of ski speeders, including the V-4X-D ski speeder, which were designed to cater to participants of the sport.
The asteroid slalom craze ended after an undetected stone mite infestation at the Orleon Belt Grand Slalom Finals resulted in several racers and their vehicles being devoured while the event was broadcast live to a horrified audience across the galaxy. As asteroid slalom bookings plummeted, Roche Machines halted production on its ski speeders and sold the remaining stock at a reduced price.
Behind the scenes
Asteroid slalom was first mentioned in the 2017 reference book Star Wars: The Last Jedi: Incredible Cross-Sections, which was written by Jason Fry.
