Description
MOZA Racing R21 Ultra Direct Drive Wheel Base – 21Nm Professional Sim Racing Power
The MOZA Racing R21 Ultra Direct Drive Wheel Base is engineered for serious sim racers who demand maximum torque, exceptional feedback detail and uncompromising build quality. Delivering up to 21Nm of torque, it provides a highly immersive and realistic steering experience suited to competitive and professional-level racing simulations.
Built around a high-performance direct drive motor, the R21 Ultra connects the steering wheel directly to the motor shaft without belts or gears. This design minimises latency and mechanical play, resulting in immediate response and highly detailed force feedback. Drivers can feel subtle surface textures, tyre slip, suspension load and weight transfer with impressive clarity.
The 21Nm torque output delivers strong and consistent steering resistance, closely replicating the forces experienced in real-world motorsport. This higher torque capacity is particularly suited to GT racing, formula cars and endurance events where steering load and feedback precision are essential for maintaining control and consistency over long sessions.
Constructed with a durable aluminium alloy housing, the R21 Ultra is designed for strength and effective heat dissipation. Its robust structure supports heavy-duty use while maintaining stable performance during extended racing stints. The compact yet powerful form factor allows integration into high-end aluminium profile cockpits and professional simulator rigs.
Advanced motor control technology ensures smooth and predictable torque delivery. Users can fine-tune feedback strength, damping and response characteristics through compatible MOZA software, tailoring the feel to match different racing titles and personal driving preferences.
An integrated quick-release system allows secure and rapid attachment of compatible MOZA steering wheels, enabling easy transitions between wheel styles for various racing disciplines. Designed specifically for PC sim racing, the MOZA Racing R21 Ultra Direct Drive Wheel Base delivers professional-grade torque, refined feedback accuracy and reliable long-session performance for dedicated sim racers.
