Moza R21 Ultra True Torque Direct Drive Wheel Base (21 Nm)
Experience professional-grade sim racing with the MOZA R21 Ultra DD Wheel Base. Featuring a 21Nm sustained torque direct-drive motor, zero-cogging flat-wire technology, 21-bit magnetic encoder, and intelligent thermal management, the R21 delivers precise force feedback, smooth handling, and immersive realism for both endurance sessions and competitive racing.
Engineered for Professionals
The MOZA R21 Ultra delivers sustained 21Nm of torque with next-gen force feedback algorithms, bringing uncompromised realism and control to every racing scenario.
All-new Zero-Cogging Flat-wire Motor
The R21 features MOZA’s next-generation custom flat-wire motor designed specifically for sim racing. It delivers 21Nm of peak torque and offers 26% higher torque density than similarly sized competitors. With true zero cogging, it ensures ultra-smooth rotation and accurately reproduces every detail—from subtle steering inputs to aggressive cornering forces—capturing the full mechanical feel of real-world driving.
21-bit Magnetic Encoder with 600MHz High-Performance Processor
With a 21-bit high-resolution magnetic encoder, the R25 delivers over 2 million points of precision, capturing every steering input and surface detail with stunning accuracy. Connect with the road like never before.
Refined Design with RGB Customization
Designed with a compact, motorsport-inspired profile, the R25 looks as serious as it performs. Dual RGB light strips along the top edges offer 16.7 million colors and fully customizable lighting effects, including real-time telemetry feedback for ABS, traction control, gear shifts, and flag signals.
New Force Feedback Algorithm
The powerful R25 DD base pairs seamlessly with MOZA’s advanced New Force Feedback Algorithm, combining cutting-edge hardware and software. This synergy delivers more realistic force feedback and enables precise tuning tailored to every driving style.
