MOZA R21 Ultra Direct Drive Wheel Base

The MOZA R21 Ultra sits near the top of MOZA's direct drive range, built around an all-new zero-cogging flat-wire motor that delivers a sustained 21 Nm of torque rather than brief peaks. That constant output gives stable, high-fidelity force feedback suited to endurance sessions and demanding competition, while the zero-cogging design keeps rotation ultra-smooth so every detail of the driving surface comes through. A 21-bit magnetic encoder with 2,097,152 PPR resolution captures over two million points of data for outstanding accuracy, and MOZA's latest force feedback algorithm translates it into sharp, responsive handling. The CNC-machined aluminium alloy housing is engineered for extreme durability, and intelligent thermal management keeps performance consistent as the base warms up. Versatile front, side and bottom mounting options let it adapt to a wide range of rigs and cockpit layouts, with an optional adjustable bracket available. Two RGB light strips add customisable styling, and the base integrates natively with the wider MOZA ecosystem of wheels, pedals and accessories. Everything is fully configurable through MOZA's Pit House software, and ports for power, PC, pedals, dashboard, shifter, handbrake and an emergency stop switch make it a capable hub for a complete setup. Running at a 1000 Hz USB refresh rate and weighing around 9 kg, the R21 Ultra is PC compatible and aimed at sim racers who want serious strength with refined detail.
