MOZA R25 Ultra True Torque Direct Drive Wheelbase
The MOZA R25 Ultra True Torque direct drive wheelbase is built for sim racers who demand uncompromising power, precision, and realism at the highest level.
Delivering a sustained 25Nm of true torque, the R25 Ultra is designed to replicate the raw forces, feedback, and control of real-world racing.
Every steering input is captured and translated instantly, giving you complete confidence whether you’re pushing through high-speed corners or managing fine corrections at the limit.
At the heart of the R25 Ultra is MOZA’s true torque sensor, paired with a zero-cogging flat-wire motor and a high-resolution 21-bit magnetic encoder.
This combination allows the wheelbase to measure and deliver force feedback with exceptional accuracy, ensuring what you feel through the wheel is exactly what the car is doing on track.
Encased in a CNC-machined aluminium housing and supported by intelligent thermal management, the R25 Ultra is engineered for long endurance sessions where consistency, reliability, and control matter most.

How the R25 Ultra compares to other high-torque direct drive wheelbases
Many high-torque direct drive wheelbases focus purely on raw force output. The MOZA R25 Ultra True Torque direct drive wheelbase goes a step further by combining power with measurement accuracy and long-term consistency.
While some wheelbases rely on estimated force feedback, the R25 Ultra uses a true torque sensor to measure steering forces in real time. This means feedback is not only stronger, but more precise, delivering a cleaner and more realistic connection between the car, the track, and the driver.
Paired with intelligent thermal control, the R25 Ultra maintains its full 25Nm output without fading during long sessions.
For sim racers who want maximum torque without sacrificing detail, control, or reliability, the R25 Ultra stands out as a more refined and confidence-inspiring direct drive wheelbase.
For sim racers who want flagship direct drive performance with slightly less torque, the MOZA R21 Ultra Direct Drive Wheelbase remains an outstanding option at 21Nm while still delivering professional-grade realism and control.
Sustained 25Nm torque output
With the MOZA R25 Ultra True Torque direct drive wheelbase, every lap delivers consistent, uncompromised force feedback.
The flat-wire motor produces a true 25Nm of sustained torque, eliminating weak spots and sudden drops in output. Whether you’re loading up the front tyres under braking or catching a slide mid-corner, the feedback remains strong, smooth, and predictable.
Combined with the 21-bit magnetic encoder, every steering input is tracked with extreme precision, allowing you to feel fine surface detail, grip changes, and weight transfer with clarity.
New force feedback algorithm with iRacing 360Hz mode
MOZA’s engineers refined the R25 Ultra’s force feedback algorithm to deliver more detailed, more stable steering feedback.
Subtle road textures, tyre load changes, and cornering forces are communicated clearly, so you’re never guessing what the car is doing. The system dynamically adapts to different driving styles, giving you consistent control across sprint races and endurance events.
When paired with iRacing’s 360Hz mode, feedback response becomes faster and more immediate, improving precision and confidence at high speed.
Smart cooling system for endurance racing
High torque generates heat, but the R25 Ultra is built to stay consistent under pressure.
Its intelligent cooling system continuously monitors internal temperatures and regulates output in real time. This ensures the wheelbase maintains stable performance even during long, demanding races.
The result is reliable force feedback with no fading, no power cuts, and no interruptions — just consistent performance from start to finish.
Native ecosystem integration
A clean, reliable setup improves both performance and comfort, and the R25 Ultra is designed with integration in mind.
With native ports for MOZA pedals, dashboards, shifters, and handbrakes, everything connects directly to the wheelbase. This eliminates the need for external hubs, reduces cable clutter, and improves overall reliability.
Your rig stays organised, expandable, and ready for future upgrades.
Frequently asked questions
Is the R25 Ultra True Torque wheelbase too powerful for casual racing?
Not at all. While it delivers a full 25Nm of torque, force feedback can be finely adjusted in software to suit casual sessions or longer endurance races.
How durable is the R25 Ultra under heavy use?
The CNC-machined aluminium housing provides excellent strength, and internal components, including the slip ring, are tested for over 10 million rotations to ensure long-term reliability.
Will performance stay consistent during long races?
Yes. Intelligent thermal management actively regulates temperature and torque output, preventing overheating and maintaining consistent performance.
How realistic is the steering feedback?
With its true torque sensor, flat-wire motor, and high-resolution encoder, the R25 Ultra delivers highly detailed, natural feedback that closely mirrors real-world driving forces.
Is mounting and integration complicated?
No. Bottom, front, and side mounting options allow the R25 Ultra to fit a wide range of rigs, and native ecosystem ports simplify peripheral connections.
How accurate is the torque sensing technology?
The real-time torque sensor offers 0.1% sampling accuracy at a 2 kHz frequency, ensuring every steering input is captured and translated instantly.
Should I choose the R21 Ultra or the R25 Ultra?
If you’re deciding between the two, it comes down to torque and sensing technology. The R21 Ultra delivers 21Nm of sustained torque and is ideal for racers who want pro-level performance without stepping into the highest torque category. The R25 Ultra True Torque adds true torque sensing and a full 25Nm output, making it better suited to elite sim racers chasing maximum force feedback, precision, and long-session consistency.
