It is seen as a definitive upgrade for serious sim racers seeking power without compromise.
Know before you buy
The 21Nm of sustained torque provides a high level of force feedback strength, allowing you to feel significant resistance during heavy cornering and detailed road textures. It is designed for serious sim racers who want a realistic, high-fidelity experience that mimics the physical demands of real-world racing.
Zero-cogging technology eliminates the 'notchy' sensation often found in lower-end wheelbases. This results in an exceptionally smooth steering rotation, ensuring that your inputs are fluid and that subtle force feedback details are not masked by mechanical resistance.
The R21 Ultra features an intelligent thermal management system specifically designed to monitor and regulate internal temperatures. This allows the motor to maintain consistent performance levels even during extended, high-intensity racing sessions without suffering from power fade.
The unit is equipped with a 21-bit magnetic encoder, which provides extremely high-resolution input tracking. This ensures that your steering movements are translated into the game with near-instantaneous precision and zero perceptible latency.
The MOZA R21 Ultra is designed to be a centerpiece for advanced setups, but you should ensure your current rig is sturdy enough to handle the 21Nm of torque. It is compatible with standard mounting patterns, though it is best paired with a dedicated aluminum profile cockpit to minimize chassis flex.
