Sustained 21Nm Direct Drive Torque for Professional-Level Force Feedback

Delivering a full 21Nm sustained torque output (not peak), the R21 Ultra provides exceptional steering detail, stronger dynamic range, and consistent force feedback even in long endurance sessions. Designed for advanced sim racers, it offers the headroom needed to run realistic forces without clipping or thermal throttling.

Zero-Cogging Motor & 21-Bit Encoder Precision

Featuring MOZA’s next-generation flat-wire zero-cogging motor and a 21-bit magnetic encoder with 2,097,152 PPR resolution, the R21 Ultra captures subtle road textures, weight transfer, and micro-corrections with exceptional smoothness and accuracy. Combined with 1000Hz USB refresh rate and iRacing 360Hz mode, it’s built for ultra-responsive competitive performance.

Premium Aluminium Construction with Advanced Thermal Management

Built with a CNC-machined aluminium alloy chassis, intelligent thermal management, and support for front, side, or bottom mounting, the R21 Ultra is engineered for demanding sim rigs. Dual RGB telemetry light strips, extensive tuning through MOZA Pit House, and broad ecosystem compatibility make it a powerful centrepiece for serious racing setups. Community discussion also often notes its strong value in the 21Nm class.
