The MOZA R21 is a racing wheel base by released by MOZA Racing on September 29, 2021.[1]

While it look identical to the R16, the R21 has more peak torque at 21 Nm. As with other MOZA wheel bases, it has a quick-release system that allows user to switch the steering wheel. The R21 use a 18-bit encoder for steering input, and has one accessory port (a RJ10 port) for e-stop switch.

The original R21, known as the V1 model, was replaced by the improved V2 model on December 7th 2023. The V2 model has a 21-bit encoder and has five accessory ports, with one RJ45 port for pedals, three RJ12 ports for shifter, handbrake, dashboard and one RJ10 port for e-stop switch.

Both models are only available in a standalone wheel base set.

On PC, the R21 is compatible with several games, but must have MOZA Racing's Pit House (which include the driver package) installed to work. Because the R21 is only available as a standalone wheel base, other separate MOZA devices (such as steering wheel and pedals) are required to be usable. Button layouts vary between equipped steering wheels/hubs.
