MOZA R21 Ultra Wheelbase is MOZA's latest flagship direct drive base, built for sim racers who demand top performance. The new zero-cogging flat-wire motor delivers a sustained 21 Nm without throttling — ideal for professional sim racing and long endurance sessions.
With a 21-bit magnetic encoder (2,097,152 PPR), every steering input and road detail is captured with exceptional precision. Powerful force feedback via the MOZA Nexgen 4.0 FFB algorithm — customize curves, interpolation, spring, damping, and friction independently via MOZA Pit House.
Intelligent cooling system with real-time temperature monitoring and smart torque regulation keeps the base cool even under high load. CNC-machined die-cast aluminum body for maximum structural integrity. Dual RGB light strips with 16.7 million colors and telemetry-driven feedback for ABS, traction control, gears, and flag signals.
Dedicated ports for pedals, shifter, handbrake, dashboard, and emergency stop — no extra USB hub needed. Supports bottom, front, and side mounting. MOZA's slip ring handles over 10 million rotations with 2 MB/s data transfer.
NOTE: The R21 Ultra is not compatible with mounts designed for the R21 V2.
