Developing New Racers, One Kart at a Time

RDX (Racing Development Worx)

Our business was born out of the passion for motor racing, the respect for the pureness of karting, and a desire to develop the next great racers (regardless of where they end up;  the list of champions that started in karting is long and ever growing).

We specialize in youth (5 to 11 years old) and young adults (12 to 18 years old) that want to experience the next level of kart racing in the Northwest, with the ownership of one of the birelART brand of karts | birelART  |  Ricciardo  |  LeClerc.  BirelART’s 60 years of focused karting business, relentless perfection in chassis + parts R&D, and dedication at race tracks around the world, is the reason these karts are the best in the world.
