MOZA R21 Ultra Wheel Base: Ultimate Power and Precision
The MOZA R21 Ultra is a Direct Drive sim racing wheel base delivering 21 Nm of constant torque for realistic and consistent force feedback, even during the most demanding sessions. Its CNC-machined aluminum housing, 21-bit magnetic encoder, and customizable RGB lighting make it a premium solution combining performance, endurance, and full immersion.

A sim racing base built for endurance
Constant torque and robust construction
The R21 Ultra delivers a sustained 21 Nm of torque, ensuring consistent feedback throughout every race. Its unibody CNC aluminum chassis provides outstanding rigidity and torsional resistance against the forces generated by a powerful force feedback system. This premium-grade design guarantees durability and stability, even in professional sim racing environments.
Precision and advanced force feedback
Equipped with a 21-bit encoder, the MOZA R21 Ultra processes over two million data points, capturing the smallest steering inputs and wheel movements. Combined with the Nexgen 4.0 force feedback algorithm, the R21 Ultra base realistically reproduces road textures, vibrations from curbs or grip loss, and the weight of heavy braking. The iRacing 360 Hz mode, tailored for the iconic racing simulator, ensures ultra-fast response with no perceptible latency, delivering smoother and more natural driving.
Enhanced immersion and full compatibility
The R21 Ultra features dual customizable RGB light strips designed to display real-time telemetry data. Beyond aesthetics, they provide visual cues such as ABS, traction control, gear shifts, and flag indicators. Natively compatible with the MOZA ecosystem, the base includes dedicated ports for direct connection of pedals, shifter, dashboard, and handbrake. The MOZA Pit House software allows fine adjustments of force feedback with personalized profiles and independent tuning of friction, damping, and wheel resistance.
