MOZA R25 Ultra – True Torque Direct Drive Wheel Base 25Nm

MOZA R25 Ultra True Torque – 25 Nm Direct Drive Wheelbase with Hardware Torque Sensor

The MOZA R25 Ultra True Torque is MOZA Racing's no-compromise flagship direct drive wheelbase — delivering 25 Nm of peak torque and the brand's exclusive True Torque hardware sensor that measures real motor torque directly rather than estimating it from current draw. With a sampling accuracy of 0.1% and a response frequency of up to 2 kHz, the True Torque sensor delivers a sharper, more linear and more predictable force feedback experience than any current-based estimation system can offer — a level of fidelity previously reserved for professional simulators. Powered by the same world-first zero-cogging flat-wire motor, the 21-bit magnetic encoder and the MOZA Nexgen 4.0 Force Feedback Algorithm as the R21 Ultra, the R25 Ultra combines next-generation hardware, software and metrology in a single CNC-machined die-cast aluminium chassis with dual customizable RGB light strips and real-time telemetry feedback.

Key Differences vs. R21 Ultra

• +4 Nm peak torque — 25 Nm vs. 21 Nm
• Exclusive True Torque hardware sensor — measures real motor torque directly at 0.1% accuracy and 2 kHz response rate, delivers more linear and predictable FFB

All other specifications (motor technology, encoder, FFB algorithm, chassis, lighting, cooling, ports) are identical to the R21 Ultra.

Key Features

• 25 Nm peak torque — true high-end direct drive performance, 26% higher torque density than similarly sized competitors
• Exclusive True Torque hardware sensor — 0.1% sampling accuracy, 2 kHz response rate, real motor torque measurement for linear and predictable FFB
• World-first 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
• 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
• Dual RGB light strips along the top edges — 16.7M 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

Technical Specifications

• Peak Torque: 25 Nm

• Motor: Custom zero-cogging flat-wire direct drive
• Encoder: 21-bit magnetic, 2,097,152 steps per revolution, 0.00017° resolution
• FFB Algorithm: MOZA Nexgen 4.0
• CPU: 600 MHz
• Housing: CNC-machined die-cast aluminium unibody
• Lighting: Dual RGB light strips, 16.7M colors, telemetry-linked
• Cooling: Upgraded intelligent cooling system with real-time temperature monitoring
• Wheel-side mount: 6×70mm PCD MOZA QR
• Software: MOZA Pit House
• Platform: PC — Xbox compatible when paired with a MOZA Xbox-licensed steering wheel

Compatibility

• Compatible with the full MOZA Racing ecosystem — wheels, pedals, shifters, handbrake, dashboards and E-Stop
• Compatible with third-party wheels via the MOZA Quick Release Adapter (steering function only)
• PC (Windows) — full functionality
• Xbox — compatible only when used with a MOZA Xbox-licensed steering wheel
• Not compatible with PlayStation consoles.

Important Notes

• The R25 Ultra does not include USB pass-through. Third-party USB wheels must be wired separately to the PC.
• 25 Nm direct drive bases generate very high torque — a rigid full-size cockpit is strongly recommended. Desk mounting is not appropriate at this performance level.
