Watch our review of the MOZA R21 wheel base

Check out our video review of the MOZA Racing R21, where we tackle the question of whether it is worth buying in 2023.


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. 

MOZA R21 Internal Direct Drive Motor

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.
