MOZA RACING R21 Ultra (V3) Direct Drive Wheelbase, 21 Nm, Black (PC)

The MOZA R21 Ultra (V3) is a direct-drive wheelbase designed for PC racing simulators. It uses force feedback technology to transfer in-game physics directly to the steering column, without the need for belts or gears. The internal motor provides 21 N·m of peak torque, simulating heavy steering loads, suspension compression, and loss of tyre grip. A high-resolution 21-bit magnetic encoder tracks wheel position to ensure subtle steering inputs are registered accurately. This provides the detailed feedback needed to react to changing track conditions.

Housed in a black aluminium chassis weighing 11 kg, the unit requires a sturdy mounting solution. It measures 140 mm wide, 135 mm high, and 248.8 mm deep, and is compatible with dedicated sim racing cockpits. The unit connects to the PC via USB and operates with MOZA RACING steering wheels. It is powered by an included 360 W AC/DC adapter. Firmware updates ensure the hardware remains compatible with future simulation software.
