While it may look almost identical to the MOZA R16 wheelbase, it sports 30% more peak torque than the R16, the secret lies in the stator and rotor inside.


The R21, designed and engineered by Moza Racing, is the first electric vehicle-grade motor used in the sim racing industry. Unlike traditional motors, the R21 utilizes a split-lobe micro slot stator and fractional slot concentrated windings to give an extremely high copper space factor. This difficult-to-engineer manufacturing process gives a 30% increase in torque and dynamic range detail without the usual temperature increase.

The rotor of the R21 is a triple staggered slanted pole design commonly found in electric motor vehicles and ensures a balanced vibration-free motor.
The combination of a high copper space factor and triple staggered slanted pole rotor results in a motor that delivers increased torque and dynamic range detail and greatly reduces cogging and torque ripple over traditional sim racing motors.

MOZA Pit House​

MOZA Pit House is a fantastic piece of software that is free to download and use and designed to maximize the potential of your Moza Racing product. With presets and easy-to-understand settings, beginners can enjoy a plug-and-play experience catered for many popular racing titles. All settings are fully customizable. Pro racers can fine-tune their setup for maximum gain feel and precision. It offers many useful functionalities.

Hands-off Protection​

This function can effectively avoid the risk of injury and quickly help restore control by detecting that hands are off the wheel. Once activated, it will quickly stop any oscillation and safely center the wheel.

Speed-dependent Force Feedback Dampening​

This function will increase the damping FFB effect as the vehicle speed increases and reduces the dampening as the vehicle speed decreases to accurately mimic a real race car, resulting in greater high-speed stability and low-speed maneuverability.


Force Feedback Equalizer​

MOZA’s FFB equalizer allows full customization and fine-tuning of the FFB effects spectrum for a perfect setup in any conditions.

Is Moza really a leading manufacturer? I have doubts about that considering its products are high to find. Also, just an additional information this price excludes the VAT and I assume the shipping fees (and probably the reseller's margin). That's why in my country it is listed, although stillnput of stock, 1437€, which is around 40% more. The first rim costs more than 600€. Do it is a minimum 2000€ budget for this peculiar model. I assume that it is the regular price for a 21nm wheel, but far from the announced price.
