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!

We went as a group of 12 for 2 birthdays and had a private room to eat in after our 3 races. All in all it was a great experience that we will definitely do again.My 2 complaints that took a star:During our 2nd race, one car stopped working. Held up the race several minutes, everyone was at a complete stop while they swapped out the dead car, then a second car wouldn't start after the 1st car was swapped out, so we had to wait longer for the 2nd car to be swapped out. Issues happen, we understood, but I think that race should’ve been started over, instead they continued after everyone was at a dead stop for over 10 minutes.Second complaint was our food delivery. We were set up for pizza and wings in the Fontana Room after our last race. We made sure the kitchen knew we were ready for our food, and the pizza arrived in the room over 45 minutes after our race and the wings arrived 30 minutes after the pizza, after several requests. We were told we would get a credit for the trouble, but haven’t seen it yet.The food was good but coordination was poor.Again, we would go again, it was a great time. Our group ranged in age from 12 to 60 , they split our races into 2 groups of 6 which was great, 12 on the track would be too many. After our races, they held a podium ceremony for each of our 2 groups and gave out medals for 1st 2nd and 3rd and medals to the 2 birthdays.

It was more fun than I expected it to be. I wished the course was a bit larger so that we could race longer.

It was pretty busy/crowded the day we went but it didn't really take too long and we were on the track racing before we knew it.

Everything was great except when I bought the package and asked for a 2XL shirt, they were out. I asked for an XL and was given a medium. I live close to 2 hours away and didn't notice until I was half way home and I have no idea when I will be back to exchange it. Needless to say, I won't be wearing it.I was contacted by Dennis from K1 and he sent me the correct size back in late Sept. Sorry it took so long to update. Thank you Dennis!

We had a great time at the Ontario Location. The only thing that was missing is an ice machine for the drinks.
