FAQs
What torque does the R25 Ultra produce?
The R25 Ultra delivers 25 N·m of sustained peak torque at 378W, powered by a zero-cogging flat-wire direct-drive motor with a 21-bit magnetic encoder (2,097,152 PPR).
What is the built-in true torque sensor?
The R25 Ultra features a built-in torque sensor that continuously measures actual output torque at 2 kHz with 0.1% accuracy. This delivers force feedback based on real physical motor output rather than current estimation.
How is the R25 Ultra different from the R21 Ultra?
Both share a zero-cogging flat-wire motor and 21-bit encoder. The R25 Ultra adds higher sustained torque (25 N·m vs 21 N·m) and a built-in true torque sensor for finer input fidelity and faster response.
Does the R25 Ultra support Xbox or PlayStation?
Xbox Series X|S and Xbox One are supported when paired with the MOZA ESX steering wheel. PlayStation is not supported. Without the ESX wheel, the R25 Ultra is PC-only.
What is the encoder resolution?
21-bit magnetic encoder with 2,097,152 PPR providing 0.00017° angular resolution at 1000Hz USB refresh rate.
How does the thermal management work?
Intelligent thermal management with real-time temperature monitoring and torque regulation. The high-efficiency flat-wire motor design ensures superior cooling and quiet operation under sustained 25 N·m output.
What mounting options are available?
Front, side, and bottom mounting supported. Optional adjustable bracket available. Dimensions: 248.8 × 140 × 135 mm. Weight: 9.1 kg.
What is included in the box?
R25 Ultra Wheel Base, power adapter (110V~220V AC → 36V DC), data cable, bolt kit, user manual, and warranty card. Steering wheel, pedals, and emergency stop switch are sold separately.
