The MOZA R25 Ultra TrueTorque Bundle is a sim racing package built around the R25 Ultra TrueTorque direct drive wheelbase with 25 Nm of sustained torque and a true torque sensor, plus your choice of steering wheel and pedal set, compatible with PC and designed for competition and professional use.
The R25 Ultra is MOZA's most powerful wheelbase: a zero-cogging flat-wire motor with 26% higher torque density than similarly sized competitors, a 21-bit magnetic encoder and a built-in torque sensor that measures real output torque at 2 kHz. It sits at the top of the direct drive wheelbase range and is the natural foundation of a high-end racing simulator.

- CRP2 (3 pedals) + Performance Kit: second-generation pedal set with load cell and clutch.
- mBooster Active Pedal Set + CRP2 throttle + extended baseplate: active brake with dynamic force feedback.
- No pedals: if you already have a pedal set and only want the wheelbase and wheel.
Compatibility
- Platform declared by the manufacturer: PC.
- Simulators: iRacing, Assetto Corsa and Assetto Corsa Competizione, rFactor 2, Automobilista 2, the F1 series, DiRT Rally, RaceRoom, Le Mans Ultimate, Euro Truck Simulator 2 and American Truck Simulator, among others.

Frequently asked questions
What does the true torque sensor on the R25 Ultra add?
It measures the motor's real output torque at 2 kHz with 0.1% sampling accuracy instead of estimating it from current draw. The result is a more linear response and more dependable control during oversteer or loss of grip.
What is the difference between the R25 Ultra TrueTorque and the R21 Ultra?
Both share the zero-cogging flat-wire motor, the 21-bit magnetic encoder and the same force feedback algorithms. The R25 Ultra raises sustained torque to 25 N·m and adds the built-in true torque sensor; the R21 Ultra stays at 21 N·m without that sensor.
Does it run hotter or louder because it delivers 25 Nm?
MOZA states that it does not: the R25 Ultra has an upgraded intelligent thermal management system with real-time temperature monitoring, and the flat-wire design improves heat dissipation, keeping operation quiet even at full sustained torque.
Do I need a reinforced cockpit for the MOZA R25 Ultra Bundle?
Yes. With 25 N·m of sustained torque and a 9.1 kg wheelbase it should be mounted on an aluminium profile cockpit or an equally rigid structure; it supports bottom, front and side mounting with an optional adjustable bracket.
Which type of driver is this bundle aimed at?
Advanced sim racers, esports teams and simulation centres competing in high-downforce GT and formula cars and in endurance events, where both sustained torque and thermal stability matter.
