Like our location in Irvine, K1 Speed Ontario offers racers a choice of two unique and challenging tracks. The layout for Track 1 features a tight and technical infield, yet also offers wide passing areas that are great for overtaking. Track 2 has a very long straightaway and several hairpin turns that demand good rhythm and a precise balance of throttle and steering. Regardless of the track that you race on (we find that many of our customers decide to try both!), racing at 40mph a mere inches from the ground with up to 12 other drivers around you fighting for position is a thrilling experience that will redefine your outlook on go karts. Our 20hp electric karts are clean, efficient, and quiet, and they offer stellar performance that may just catch you by surprise! Whether you're interested in participating in our next race event of you want to challenge your friends in our Arrive and Drive, our karts are enormously fun. We invite you to contact us if you have any questions. Serving Riverside County and the Inland Empire, including Rancho Cucamonga, Corona, Pomona, Murrieta and Mira Loma, our Ontario indoor go kart racing center is one of the finest in Southern California.

The Super Track at K1 Speed Ontario is available for PRIVATE EVENTS, Challenge GP events,
and for Arrive and Drive races on "Super Track Mondays".
Ontario offers two tracks; Track 1 is a great balance of speed and wide turns for passing which makes a perfect race track for those beginner and intermediate level drivers, Track 2 boasts the longest straight away of any track that we are aware of after exiting the challenging Triple hairpin turn. It is the best track for those kart racers looking for a challenging racing experience. The Super Track is the largest indoor kart track in the country and combines the best of both worlds; only available for private parties and special racing events.
