Column: Why Karting Isn’t Succeeding in Sim Racing

Karting is the first rung on the motorsport ladder, so why is it so hard to accurately replicate within sim racing? With endless amounts of circuit and kart combinations, why is karting so difficult to simulate?

Two approaches to karting dominate the sport in the world of sim racing. Assetto Corsa's mods have the advantage of volume of content which is to be expected, and dedicated karting sims like KartSim, KartKraft and Kart Racing Pro are designed purely around the idea of karting simulation. KartSim is a DLC pack for Studio 397's rFactor 2 which sets it aside from the other two offerings in terms of a pure karting simulation.

These kart titles are aimed more towards karting hobbyists and professionals than the average sim racer. This demographic makes use of companies such as Next Level Racing which offer entire cockpits dedicated to karting. An investment the average sim racer most likely can not justify in 2024.

But are these cockpits worth investing in? Karting is one of the most physical forms of motorsport, so why can it not be simulated realistically? We will hear from ex-Top Gear stig, Ben Collins, on his opinions on karting simulations and delve into some options for you to try from your rig or desk.

Can You Accurately Simulate Karting?​

As previously mentioned, karting is one of the most physical forms of motorsport. Driver weight transfer and movement are key to success when finding that extra tenth of a second on your competition. Simulating that physicality is impossible, especially if you are using a karting rig that doesn't support many of the motion devices found on bigger rigs used to simulate cars.

Karting has always been a bit of a black sheep in the sim racing community. A lot of people's rigs are not set up to suit a karting seating position and that ruins their immersion. As well as people's rigs not being up to the task, outside of Automobilista 2 and Assetto Corsa mods, the karting offerings in the mainstream sim racing titles are lacklustre at best.

To be clear, the ability to simulate a karting race is of course possible, as mentioned there are dedicated titles to the discipline. However, to accurately depict how a kart feels, handles and behaves is nearly impossible without a seriously complex motion setup.

"Some things are much harder to get right than others, for example go-karting. Nobody should bother. It is impossible to replicate a two-stroke go-kart right now" Ben Collins, ex-BBC Top Gear Stig and decorated racing driver talking to Michel for OverTake.gg at Silverstone earlier this year.

Assetto Corsa Karting​

One title that stands aside from the rest of the karting offerings in sim racing is Assetto Corsa. Like with the rest of the catalogue in Kunos' much-loved simulator, the quality of the third-party karting content can range dramatically. Be aware of this when downloading tracks and karts. You can not expect them all to be up to first-party content level.

Your options here on OverTake.gg are plentiful. You can drive everything from the common Sodi rental karts that are present at nearly every single indoor and outdoor karting centre, right up to the incredibly fast 125cc shifter karts. All for free.

GoKart 0.3a - rex1825

The original kart mod for Assetto Corsa, this mod came out in October 2014. Two months before Assetto Corsa was officially launched out of early access in December of that year.


This mod is therefore a bit out of date and certainly has quirks. However, the raw and simplified feeling of an early Assetto Corsa mod is still amazing fun if you don't look into it too far. Rex1825's creation laid the groundwork for the following two kart mods that have been so successful.

GoKart 50ccm - 13bhp/11NM, 70kg, ~105km/h
GoKart 100ccm - 22bhp/15NM, 71kg, ~125km/h
GoKart 125ccm - 31bhp/21NM, 71kg, ~140km/h
GoKart 125ccm Shifter - 41bhp/28NM (Turbo), 74kg, ~155km/h, 6-speed


GoKart 0.5c - Cercata

The second mod in this mini-list takes from the previous iteration of the go-kart mod and evolves it into a much more modern offering. A thorough overhaul of the kart's physics, liveries and model makes this a huge step towards modernizing Assetto Corsa's karting offering.


For messing around and racing on the tight and twisty circuits, this mod is really hard to beat. The scale of engines and variety of karts is also superb.


  • 270cc -> 8bhp, 150kg
  • 390cc -> 12bhp, 150kg
  • 250cc -> 28bhp, 143kg
  • 50cc -> 13bhp, 70kg
  • 100cc -> 22bhp, 71kg
  • 125cc -> 31bhp, 71kg
  • 125cc shitfer turbo -> 41(28)bhp, 74kg
  • 125cc shifter SGM -> 48bph, 74kg

Sodikart Sodi RT10 - alpadev

My personal choice and a community favourite as well. A fantastic mod created as an evolution of the previous two karts listed. The Sodikart RT10 is the pinnacle of rental karting. If you have ever driven a go-kart, it's probably been this kart!

This kart holds a special place in my heart because, In a previous life, I used to service these karts and marshall at a circuit for the British public in all weathers. Driving this kart in Assetto Corsa brings back memories and is surprisingly accurate when you take the physical forces out of the equation.

Karting is such a crucial stage in a racing driver's career. It teaches and punishes drivers early on with its physicality and close racing. It is a shame that karting in sim racing doesn't quite match the level of ingenuity that real karting has. In the future, there are bound to be revelations. However, until that day comes karting is stuck and plateauing in terms of realistic simulation and player numbers.

What do you think about karting in sim racing? Do you think it can be simulated realistically? Let us know on X @OverTake_gg or down in the comments below!

Kartim on rF2 is without any doubt the best, I have EU and UK pack, more than 41 tracks, the best of the best with the rF2 physics, it's the quality, far ahead any other kart game.

Simple. There is no sim that accurately portrays what is happening behind the wheel. They seem to be able to have all the data in the world but then not use it all and you end up with something approaching nothing. Makes you wonder about everything else we race!
 
Well, I have been told by someone who ones one ( not this one but the modern generation), it drives like a kart. Problem is however, he has not raced in a kart, so I think he does not really knows the difference.

Karts don't lift wheels like these :)
I had mate with Mk II, full house, straight cut box.
It had that much power it would axle tramp and jump off the ground pulling little wheel stands :roflmao:
People wanted a ride ended up like they seen a ghost.

How do these lift wheels?
 
Rear wheels when cornering hard.

You see a few examples here

What do you mean? A mini is lifting rear wheels when cornering hard? What is the difference with a kart then? Or do you mean in a kart the driver causes this with his body and in a mini it is the mini itself who causes it?

I've tried karting in Assetto Corsa, but I wasn't happy with the free mods. The AI was mostly slow or just stayed on the starting grid.

I used to play KartKraft, but the developers dropped it unfinished.

The only good karting DLC I found was KARTSIM KART PACK by Reiza Studio for rFactor2.
 
I used to drive very occasionnally kart on sim and a bit more rental kart and it was alright. Then I bought a 2-stroke 125cc and as some have said, even a good DD cannot make it for the lack of feels. I think it's mostly due to the absence of suspension, your body is the suspension where cars will smooth everything.
 
Like with motorbikes, karts you use your weight and body as much as anything else, cars you just press pedals and turn a wheel so relates to sim racing perfectly (apart from game devs STILL thinking cars have glass tyres and roads are ice).

In AC all karts are clueless to how they should drive and feel and as such it offers a really poor driving experience.
 
"Do you think it can be simulated realistically?"

As realistically as any other motorsport.

I think it has not been popular for the same reason club racing mods have not been - virtually anyone can rent a kart for an afternoon and have fun, just like most of us have driven MGs and Triumphs and VWs.

What is most popular in sims? The "big leagues", people want F1 and NASCARE and "Indycar" and ALMS and GT, not 90 hp four-bangers, much less 15hp go-karts.

Years ago someone started a kart mod for GTR2; two threads on Nogrip for it asking for beta testers, painters, etc., received so little response that I think the guy abandoned the project entirely a few months later.

Fairly certain Reiza didn't do Kartsim, Kartsim is a UK based company. Reiza released a DLC pack for RF2 but that was some of their AMS1 content ported over. Otherwise, we would have had those karts and tracks in AMS1 and 2, which we don't.

Where is the UK kart track pack? I've found the Kartsim package and then the euro track pack but that doesn't tally up to 41 kart tracks, I've only gone and looked as that piqued my interest and I was going to purchase.
 
(Hated) opinion:

Karting in sims feels more realistic than race cars.

In karts, the FFB is strong and direct (easily to simulate).

Why unpopular? -Maybe 99.99999999% of world population don't have sim rigs?
 
With most karts that we have tried in a simulator, you go through the bend on four wheels and you suffer from too much understeer. And those are rFactor, rFactor2, Assetto Corsa, Kart Racing Pro and Kart Sim (in rF2). We have not tried KartKraft ourselves, but we were told that it is disappointing in terms of realistic driving characteristics compared to Kart Racing Pro.
Exactly what I feel in sims without being able to put a finger on it (I only drove rental karts), which you just did. I can see that in videos, it looks natural, but it's so hard to replicate in sims, as you go into understeer ot risk oversteer if you unsettle the kart with too brutal inputs (which could levitate that 4th wheel). I would say the simulators should include automatic body moves (even giving the player the choice of their height and weight) for a more realistic experience, although something they should manage would be out of their control. As an option, waiting for real body moves implementation (it may be doable through VR headsets with head side movements).

I haven't been playing karting games for a while because my sim racing time has been limited. In my memory, Kart Racing Pro is the most satisfying in terms of driving but all Karting sims are enjoyable (and with different tracks).

About why karting is not more popular in simracing, it is just not that popular IRL as an entertainment. Also, it is not an easy discipline at all : a complete different driving experience and without drivings helps and without downforce, and running on unusual dedicated tracks. And the only ambitious dedicated modern title about Karting was Kartkraft which has been abandoned. It's a pity but it is as it is. It is also a shame Kart Racing Pro, the other, and much older, dedicated title, has always been lacking the offline racing ambition while maintaining quiet a high price for the base content.

In the country were I live (the Netherlands) karting has allways been a bit populair as an entertainment, but with the succes of Max Verstappen it has become much more populair. Many indoor karting tracks have been modernized in recent years. The tracks have been completely renovated and they have switched to the latest generation of electric karts. Good for the environment and less smell and noise, but more entertainment and less sporty. The karting track where many competitions were organized, the Dutch Open Championship (the "DOK") was organized every year and where competitors from all over the country trained (of which three years in a row became world champions indoor karting) has changed hands and been transformed into an entertainment karting track. Great for the general public, but a shame for the real enthusiasts. So for our country, I can't say it is not that popular IRL. But at the same time I think most people who are going to entertainment karting tracks are not driving in sims at home. And I guess if they do so, they like to drive F1 in it, not something they also can do IRL.
