Sodi Sigma RS3 2022

SODI Sigma KZ 2022 version came out with the latest advancements in its frame, build, safety, and graphics for data logging. Some would like to call it ‘The Ultimate Racing Kart of 2022’, but let’s look at it before we believe.

This ultimate kart by SODIKART has been equipped with the latest technologies in terms of data logging systems, hydraulic brakes, and steering tie-rod. On top of everything, this chassis is compatible with medium tires and engines like Rotax and x30.

We will be looking at this kart model in detail to establish whether it suits your race kart requirements or not.

Salient Features

SODI Sigma RS3 2022 has just been upgraded with a modified front chassis for better performance and compatibility with engines such as Rotax, x30, and OK engines. Following are some salient features of this go-kart model:


Sodi Sigma RS3 uses the latest updated MYCHRON 5 for data logging. MYCHRON 5 is known as the karting’s favorite as it features a GPS frequency of 25 Hz to receive signals from the satellite with lightning speed.

It can carry the whole track database to keep you informed of your exact location. The internal 5 GB battery is reliable enough to run throughout your race track.

New RS3 Frame

Sodi Sigma RS3 uses the new RS3 go-kart frame, which has been designed to reduce the wear and tear of the rear tires, reduce understeer, and improve overall performance.

The new RS3 frame splits the torque between the rear wheels to ensure safety and provide maximum turning angle. The drive torque delivers to the right rear wheel when the kart turns left. When you turn right, the reverse happens.

This provides easy control to the kart driver when taking turns and improves the lifespan of the kart, too, by enabling excellent tire wear.

Brake Systems

SODI Sigma RS3 uses a four-piston hydraulic brake system with a floating and turbo ventilated brake disk. Just recently, with the new RS3 frame, SODI incorporated a master cylinder in the hydraulic brake system. The front brake disc is the KZ 140 mm for more efficient and responsive brake systems that last for years.

30 mm Tubing

SODI Sigma chassis uses 30 mm tubing, which provides just the right grip and stability. It is tougher and stiffer than the 28 mm tubes and provides better grip than the 32 mm chassis. A 30 mm chassis can easily support the driver weights of up to 180 lbs.

A Wide Wheelbase

A wide wheelbase of 1050 mm ensures safety by reducing force on the corners. When the kart takes a turn, it has a safe chance of skidding compared to the go-karts with a narrower wheelbase.

A wide wheelbase also reduces the torque or the turning angle for the kart, but SODI here has made just the right compromise between the two to ensure the safety of the go-kart and its driver.

Fuel Tank

SODI Sigma RS3 uses a fuel tank of 8 liters, which is the optimum fuel tank capacity for a full-sized chassis. With SODI sigma RS3, you do not have to worry about the weight that adds to the fuel tank. Its engineering makes sure the dynamics do not change with the tank’s weight.

Safety Features

SODI Sigma uses a protective base plate for the brake discs. The brake pedal with 2 attachment points is another safety feature that protects the kart brakes on the race track from sudden emergency brake failure.

The integral chain cover and the anti-locking add another layer of safety to your kart ride, whether you are on the race track or just having fun.

Eccentric Kit

This ultimate racing kart uses a modified eccentric kit that uses eccentric nuts. This change lets you easily mount and dismount the frame and engine at almost all heights of the frame. Besides, it also maintains the wheel alignment on the race track.

Steering Tie-rod Protection

All SODI go-karts use the steering tie rod protection to prevent the wheels from choking when the wheel reaches its stop. It also keeps your steering right under your control, preventing it from wandering. A quality steering tie-rod also prevents uneven wearing of the tires.

Go-Kart Buying Guide

If you are a karting enthusiast. Or just beginning to discover your go-karting interest, the first thing you need is a go-kart! When buying one, the following are some things to keep in view:

The Frame or the Kart Chassis

The chassis of the go-kart is all it is made of. It does not use suspension, and the quality and condition of the frame and its aerodynamics will play the most important factors in you winning the race and staying safe.

The Manufacturer

Go-karts are all about the right dynamics, weight, and quality of the build material, and all of these depend on the expertise of the manufacturer. Reputable go-kart producers can also customize the chassis, engine, and seat adjustments according to your weight, height, and specific requirements.

Besides, your go-kart is an investment. Put your money in a kart that retains its value and performance for years.

The Standards of Homologation

The world of go-kart racing has some homologation standards set by the authority called the FIA (International Automobile Federation). The karting rules and standards are made by the CIK (International Karting Commission) mainly. A reputable manufacturer will satisfy you with the homologation standards of the particular kart race of your choice.


Your ideal go-kart should feature a quick start and a powerful and energy-efficient engine. After the chassis, the engine has to be your deciding factor when buying a go-kart.

The Bottom Line

SODI Sigma RS3 is definitely the ultimate racing kart you can get your hands on. It suits the medium-end kart race experts with all the latest technology and upgrades. You can use your Sigma RS3 chassis with the engine you like and enjoy your investment for years.
