by Moza

Moza R21 Direct Drive Wheel Base

21Nm of Pure Direct Drive Torque from an Industrial-Grade Motor

With 21Nm of power behind the R21, feel everything modern racing cars have to offer. Every bump, slip and slide can be felt for unbeatable class leading immersion.

Six Unique Approaches to Direct Drive Design

Developed by experts in the electric motor field, the R21 motor utilizes 6 unique design approaches to ensure a smooth racing experience. V-shaped struts and fractional slot-concentrated windings are used to ensure maximum torque without notchiness. The R21 sports a 30% larger torque output than other similar models.

Sleek, Modern Design

Inspired by current supercar trends, the R21 sports a robust design and two-tone paint finish.

Sturdy, All-aluminum Body

The R21 is made of aluminum alloy, giving the base a rock-solid feel and weight.

Ultra Low Static Torque

Feel everything through an optimized motor design, offering practically zero torque ripple, notching or cogging. Combined with powerful torque delivery, hard braking, curbs, and drifts are clearer and stronger than ever before.

Superior Temperature Control

Enjoy reliable, steady temperature performance with the R21. Even for extended endurance racers, the R21 will never reduce output or attenuate due to overheating. Real-time onboard temperature monitoring means you will never miss a session.

62,144 Points of Resolution

The R21 encoder incorporates ultra high precision wheel position monitoring, allowing for accurate and clear feedback when racing.

Hands-off Protection

This function can effectively avoid the risk of injury and quickly help restore control by detecting that hands are off the wheel. Once activated, it will quickly stop any oscillation and safely center the wheel.

Speed-dependent Force Feedback Dampening

This function will increase the damping FFB effect as the vehicle speed increases and reduces the dampening as the vehicle speed decreases to accurately mimic a real race car, resulting in greater high-speed stability and low-speed maneuverability.

MOZA Pit House Control Software

MOZA Pit House Control Suite allows for maximum customization of your racing experience. See the status of each device, set maximum turn angle, force feedback, pedal travel, LED indicators, and much more.

With presets and easy to understand settings, beginners can enjoy a plug and play experience catered for many popular racing titles.

Force Feedback Equalizer

MOZA’s FFB equalizer allows full customization and fine-tuning of the FFB effects spectrum for a perfect setup in any conditions.

One-click Launching

Save your game configuration in the MOZA Pit House launcher to quickly launch into a game from within the Pit House.

Next Generation FFB Filtering Algorithm

The R21 DD base is powered by MOZA's latest force feedback filtering algorithm, providing enhanced dynamic feedback that renders oversteer and understeer with greater clarity and richness.

Dual-Mode Communication

The base and the steering wheel are connected via a military-grade wired conductive slip ring with a lifespan of more than 5 million revolutions. Simultaneously, the base communicates wirelessly with the wheel. This distinct patented design delivers exceptional stability and durability, allowing for seamless, infinite high-speed rotation.

Cloud-based Mobile App Control

Enjoy on-the-fly changes using the MOZA app! Force feedback, pedal settings, and more can all be changed in real-time. One-click importing allows easy hassle free setup transfers to new devices.

Multiple Connection Ports

With the ability to directly connect MOZA pedals, shifter, handbrake, and digital dash to the base, you not only conserve USB ports on your PC but also unlock the potential for simultaneous use of multiple devices.

Front Mount Compatibility

Featuring four front-facing holes designed for MOZA's front mounting bracket, this versatile design supports both front and side mounting options, optimizing legroom and catering to formula-style seating preferences.
