25 N·m, and a True Torque Sensor
The Moza R25 Ultra is MOZA's flagship direct drive wheel base and the only one in the range with a built-in true torque sensor. Real-time torque sensing samples at 0.1 percent accuracy with a response frequency up to 2 kHz, closing the loop between what the game asks for and what actually reaches your hands. Behind it sits a sustained 25 N·m zero-cogging flat-wire motor, a 21-bit magnetic encoder and a 600 MHz processor, in a CNC-machined die-cast aluminium unibody.
Closed-loop force feedback
Most wheel bases send a torque command and assume it arrives. The R25 Ultra measures what is actually being delivered, thousands of times a second, and that is the single biggest difference between it and everything below it in the range.
MOZA's flagship wheel base
Built for esports and professional use, the R25 Ultra combines the most torque in the MOZA range with the sensing hardware to place it precisely, in a compact motorsport-inspired body.
A true torque sensor
The R25 Ultra is equipped with a true torque sensor delivering 0.1 percent sampling accuracy and a response frequency up to 2 kHz. It captures your steering input precisely, for sharper handling, tighter control and detail the other bases estimate.
All-new flat-wire motor
MOZA's next-generation custom flat-wire motor offers 26 percent higher torque density than similarly sized competitors, with true zero cogging for ultra-smooth rotation and no notchy detents.
Over two million points of precision
A high-resolution 21-bit magnetic encoder feeding a 600 MHz processor captures every steering input and surface detail with stunning accuracy, so nothing the tyres are telling you gets rounded away.
Compatible across the board
iRacing with a 360 Hz high-frequency mode, plus Assetto Corsa, Le Mans Ultimate, the F1 series, WRC, Automobilista 2, rFactor 2, RaceRoom, Project CARS, Forza, BeamNG.drive and dozens more.
No throttling back
An industrial-grade motor engineered for durability and thermal efficiency delivers a sustained 25 N·m without throttling, which is what makes it suited to professional-grade racing and long endurance sessions.
Runs cooler under load
A fully upgraded cooling system with ample motor headroom, real-time temperature monitoring and smart torque regulation, so peak performance holds through the most demanding races.
Slip ring built to last
MOZA's slip ring handles over 10 million rotations and transfers data at 2 M/s, giving a solid connection and lag-free communication between the wheel and the base.
No USB hub required
Dedicated ports for all the major MOZA peripherals mean pedals, shifters, dashboards and a handbrake plug straight into the base, keeping the rig tidy and your PC's USB ports free.
Bottom, front or side
All three mounting orientations are supported. At 25 N·m an aluminium profile cockpit is what you want under it, and the mounting options give you room to lay the rig out properly.
Lighting that tells you something
Dual RGB light strips along the top edges give 16.7 million colours and fully customisable effects, including real-time telemetry feedback for ABS, traction control, gear shifts and flag signals.
Stops the oscillation
The base detects when your hands leave the wheel, quickly stops any oscillation and safely centres it. At 25 N·m that is a safety feature, not a convenience.
Shape the force feedback yourself
MOZA's advanced force feedback algorithm pairs the hardware with the tuning tools to use it. Everything below lives in MOZA Pit House on PC, with cloud-based configuration so a setup follows you to a new machine.

- iRacing 360 Hz mode for richer, more responsive force feedback, enabled through Pit House
- FFB interpolation smooths abrupt torque spikes and dips into a natural, progressive curve
- Game FFB decoupling splits the signal into individually adjustable components
- Force feedback equaliser filters out noise and keeps only the cues that matter
- Custom non-linear FFB curve tuning helps you sense traction loss sooner
- Real-time temperature monitoring with smart torque regulation
- Cloud-based app configuration, so your settings move with you
- Free MOZA Pit House download for Windows
What the flagship gives you
-
Built-in true torque sensor
Real-time torque sensing at 0.1 percent sampling accuracy and up to 2 kHz response. The R25 Ultra is the only base in the MOZA range with it.
-
25 N·m sustained torque
An industrial-grade motor that holds its output without throttling, for professional-grade racing and long endurance stints.
-
Zero-cogging flat-wire motor
26 percent higher torque density than similarly sized competitors, with genuinely smooth rotation and no notchy detents.
-
21-bit encoder and 600 MHz CPU
2,097,152 points of resolution feeding a fast processor, so fine surface detail survives instead of being rounded off.
-
CNC-machined aluminium unibody
A rigid die-cast aluminium body for the structural integrity and torsional rigidity 25 N·m demands, without unnecessary weight.
-
Complete ecosystem ports
Pedals, dash, shifter, handbrake and an emergency stop switch all plug straight into the base, keeping the rig tidy.
Where the R25 Ultra sits
All three Ultra bases share the same zero-cogging flat-wire motor platform, the 21-bit encoder and the 600 MHz processor. What separates them is torque, physical size and, on the R25, a true torque sensor.
| Model | Torque | Best for |
|---|---|---|
| Moza R16 Ultra | 16 N·m constant | The compact Ultra, 206 mm long. Serious torque in a base that still suits a wheel stand or a mid-size cockpit. |
| Moza R21 Ultra | 21 N·m sustained | The flagship all-rounder. More loading through the wheel for GT, formula and endurance racing, on a rigid cockpit. |
| Moza R25 Ultra | 25 N·m sustained | Maximum torque, and the only one with a built-in true torque sensor for real-time torque sensing. Esports and professional use. |
