Extended Product Information

FAQs

Is the Moza R21 Ultra compatible with consoles?

No, the Moza R21 Ultra is designed exclusively for PC platforms.

Does this wheelbase come with a steering wheel rim?

No, the R21 Ultra is a wheelbase-only unit; you will need to purchase a compatible Moza steering wheel separately.

How do I mount the R21 to my rig?

The R21 supports bottom, front, and side mounting configurations to suit various cockpit styles.

Can I use pedals from other brands?

The R21 features native Moza ecosystem support, but you can typically use third-party USB pedals by connecting them directly to your PC.

What is the benefit of a 21-bit encoder?

The 21-bit resolution provides over 2 million points of data per rotation, resulting in incredibly granular and smooth steering feedback.

Troubleshooting

Wheelbase is not detected by the PC

Verify the USB connection, try a different USB 3.0 port on the motherboard, and ensure the Moza Pit House software is running.

Unexpected oscillation or shaking

Check if the 'Hands-off Protection' has been triggered; if not, recalibrate the wheel center in the software.

Forced feedback feels weak during use

Check the temperature monitoring in the software to ensure it is not throttling; ensure the base has adequate airflow.

Setup, Compatibility & Care

To maximize the lifespan of your R21 Ultra, ensure it is securely mounted to a rigid aluminum profile rig using the side, front, or bottom mounting points. Because of the high-torque output, standard desk clamps are not recommended as they may not provide sufficient stability. Connect the wheelbase directly to your PC via the provided data cable. To maintain the unit, keep the air intake vents free of dust and debris to ensure the cooling fans function optimally. Always ensure the firmware is updated through the Moza software suite to keep the force feedback algorithms current. Do not attempt to open the aluminum housing, as this may void the warranty and expose the delicate internal motor and encoder components.
