MOZA R21 Ultra – 21 Nm Direct Drive Wheelbase with Zero-Cogging Flat-Wire Motor
The MOZA R21 Ultra is MOZA Racing's new-generation flagship direct drive wheelbase — the world's first wheelbase equipped with a custom zero-cogging flat-wire motor, the same technology used in new-energy vehicles and aerospace engineering. Delivering 21 Nm of peak torque with 26% higher torque density than similarly sized competitors, the R21 Ultra combines next-generation force feedback hardware with the brand-new MOZA Nexgen 4.0 Force Feedback Algorithm for ultra-smooth rotation, perfectly clean response and exceptional detail. Built around a CNC-machined die-cast aluminium unibody for maximum torsional rigidity, a 21-bit magnetic encoder (2,097,152 steps per revolution, 0.00017° resolution), an upgraded intelligent cooling system and dual customizable RGB light strips with real-time telemetry feedback, the R21 Ultra is a true high-end base at a remarkably competitive price.
Key Features
- 21 Nm peak torque — world-first zero-cogging flat-wire motor, 26% higher torque density than comparable bases
- Zero-cogging flat-wire motor — eliminated cogging, ultra-smooth rotation, less noise, high-precision force feedback
- MOZA Nexgen 4.0 Force Feedback Algorithm — refined for the new generation, more realistic FFB and precise tuning
- 21-bit magnetic encoder — 2,097,152 steps per revolution, 0.00017° resolution
- Upgraded intelligent cooling system — real-time temperature monitoring and smart torque regulation maintain peak performance under sustained load
- CNC-machined die-cast aluminium unibody — exceptional structural integrity and torsional rigidity, optimized weight
- Dual RGB light strips along the top edges — 16.7 million colors, fully customizable, real-time telemetry feedback (ABS, traction control, gear shifts, flag signals)
- Comprehensive port array — dedicated connectors for all major MOZA peripherals (pedals, shifter, handbrake, E-Stop)
- MOZA Pit House software — full FFB customization, telemetry RGB profiles, mobile app control
