What customers say
The Moza R25Ultra is celebrated as a flagship direct drive wheelbase, primarily for its exceptional force feedback fidelity and premium build quality. Users consistently praise the immense 25 Nm torque reserve, which delivers incredibly detailed, distortion-free feedback, allowing subtle road and chassis movements to be felt with clarity. This significantly boosts immersion. The CNC machined aluminum chassis is viewed as robust and built to last, justifying the investment for serious sim racers. Integration within the Moza ecosystem is seamless. While positioned at the high end, the R25Ultra offers competitive value against other 25 Nm units. Potential buyers must ensure they have a very rigid rig to fully harness its power.
Know before you buy
Zero-cogging means the motor rotates smoothly without the 'notchy' feeling often found in lower-end wheelbases. This allows for seamless, fluid steering inputs, which is essential for maintaining control during precise cornering.
Yes, you will need to ensure your MOZA Pit House software is updated to the latest version to enable the 360Hz high-frequency simulation mode. This mode significantly improves the detail and responsiveness of force feedback within iRacing.
The wheelbase is designed for high compatibility and supports bottom, front, and side mounting configurations. This flexibility allows it to integrate into almost any standard aluminum profile rig or dedicated sim racing cockpit.
While 25Nm provides professional-grade force, the output is fully adjustable through the software. You can dial back the intensity while you build strength, allowing the unit to grow with your skill level over time.
The 21-bit encoder offers extremely high resolution, meaning it can detect even the most microscopic steering movements. This translates to better track surface detail and more accurate self-alignment of the steering wheel.
No, the MOZA R25 Ultra is designed exclusively for PC use via a USB connection. It does not support native console plug-and-play functionality.
