    Indoor Go Kart Racing Ontario, California

    Once home to a major motorsport venue in the 1970s, Ontario Motor Speedway, Ontario is now home to one of the best indoor go-karting locations in the country: K1 Speed, Ontario.

     

    Our 85,000-sq. ft. location is home to not one, but two indoor asphalt courses for double the occupancy and even less waiting. Track 1 offers a challenging series of technical corners, while Track 2 delivers a variety of fast and slow corners that is perfect for the novice or child. The K1 Speed, Ontario location also offer two distinctly different meeting rooms – one with leather couches for a laid-back social gathering, or a traditional meeting room with tables and chairs for parties and company events. Our on-site Paddock Lounge restaurant offers delicious food and refreshing beverages for all ages, while our video arcade and tabletop games keep the entertainment going.

     

    Known as a fun thing to do near both San Bernardino County and Riverside County, Fontana, Rancho Cucamonga, Upland, Chino, PomonaOntario Mills, Toyota Arena, Victoria Gardens, and Ontario Airport, K1 Speed Ontario is the perfect destination for company functions, corporate events, hosting special events, or for a daily dose of adrenaline. And if you’re in town for an event at the Auto Club Speedway, we’re just a mere four miles away. Come race with us today!

     

    One of the best indoor go kart tracks in Southern California!

    Arrive & Drive Racing – Race Any Time

    Though we offer a number of race packages that are ideal for special events, team building exercises, and corporate functions, the public is invited to come in anytime during regular business hours and enjoy the thrill of indoor go-karting. At our Ontario location, we operate not one, but two tracks. With the exception of private closures and our monthly Challenge GP series, these tracks are open to the public for Arrive & Drive racing. Simply show up, suit up, and race! Our high-performance electric karts have 20hp motors and produce maximum torque from 0 rpm, and are an absolute blast to drive. If you’re accustomed to lawn mower-powered karts that are heavy and cumbersome, be prepared to have your entire outlook on go-karts changed!

    Group Events for Any Occasion

    And if you’re looking to host a kid’s birthday party, teen birthday party, adult birthday, bachelor / bachelorette party, corporate event, or team building exercise in the Inland Empire / Ontario area, then K1 Speed is here for you! We’ve got everything you need to make your event memorable: private racing, a reserved time, delicious catering options, and private meeting spaces for conferences or celebrations. Take a peek at our Group Events page to learn more about our events or fill out an online booking form now and an events specialist will be in touch with more information tailor-suited to your needs.

    Do You Have the Mettle? Test Your Skill

    An Arrive & Drive race consists of a battle against the clock with up to 11 other drivers on the track. Rather than race for position, which rewards luck and blocking skill as much as it does pure driving talent, our time trial races demand consistency, skill, speed, and strategy. Setting a fast lap time often involves navigating around slower drivers and creating a window for yourself on track so that you can set a fast lap time unimpeded. If you get caught up in a neck-and-neck battle, don’t be surprised if the back-and-forth action hurts your lap times! Just like in Formula One, the key to setting a fast lap time is often getting as far away from other drivers as possible.

     

    Racers at our K1 Speed Ontario indoor go-karting track can purchase a single Arrive & Drive race or a combo pack of 3 races. There are also K1 Speed gift cards available if you want to purchase races for a friend or family member. During the race, competitors can track their performance in real time via live telemetry, and after each race, a competitor’s overall ranking is updated, showing his or her rank in comparison to the more than one million racers to have hit the track at K1 Speed.

    Hit the Track Today

    We encourage you to come in to K1 Speed Ontario today. Our indoor go-karting location is conveniently located for residents of the Inland Empire, including Southwest San Bernardino County and Riverside County. To enquire about private closures, please feel free to call. We look forward to seeing you soon!

    I celebrated my son’s 14th birthday here at K1 Speed in Ontario, CA. It was my first time there and I was super impressed. From the easy check in to the private party room I was given, my experience was great. My son and his friends had a blast and the food was delicious. Jacob and Monica were very friendly and made sure we had everything we needed. The staff running the food/bar area was very attentive. I highly recommend K1 Speed to families who have teenagers who like speed!

    Legitimately kinda dumb how fast these karts are. Like mini f1 cars. Super fun. Wish there was one in kentucky. The merchandise is cool all though I think I was given a kids size hat.. I was here on a buisness trip so couldn't go back to exchange it. But no biggie. If u have the time it's a must.

    My daughter had a blast. She was tall enough to race with the adults. They made sure she had all the info, (first time) and made sure she was ok any time she hit the wall or spun out. She quickly got the hang of it. We waited maybe 10 min for the first race and she was able to do back to back races after that. We went during the week and right at opening so not busy at all. Will definitely be back

    It was almost no wait, but just fyi, for the adult race, be aware there are some really aggressive drivers that will bump you out of the way to pass you, which is dangerous to me! The place is clean but hardly or no air conditioning, probably too hard to cool such a large area. The employees are nice :).Overall it's a good place with no gas smell since they are electric run, hardly any wait, clean, nice employees.

    We went to the Ontario location for my son's birthday and my other son's send off for the Coast Guard. Jasmine helped us with checking in and got us discounts we didn't know were available! She was the best. My family has a great time and made some lasting memories. Thanks, Jasmine! Highly recommend.
