Unlock pro-level sim racing precision with the MOZA R25 Ultra True Torque Direct Drive Wheel Base. Featuring a 25Nm sustained torque motor, built-in true torque sensor, zero-cogging flat-wire motor, 21-bit magnetic encoder, and advanced FFB algorithm, the R25 delivers unmatched responsiveness, realism, and control for esports and professional racing enthusiasts.
All-new Zero-cogging Flat-wire Motor
The R25 features MOZA’s next-generation custom flat-wire motor designed specifically for sim racing. It delivers 25Nm of peak torque and offers 26% higher torque density than similarly sized competitors. With true zero cogging, it ensures ultra-smooth rotation and accurately reproduces every detail—from subtle steering inputs to aggressive cornering forces—capturing the full mechanical feel of real-world driving.
Real-time Torque Sensing
The R25 Ultra Base is equipped with real-time torque sensing, delivering a sampling accuracy of 0.1% and a response frequency of up to 2 kHz. This advanced torque sensor captures your steering input with precision, giving you sharper handling, tighter control, and unparalleled detail.
Sustained 25Nm Torque Output
Powered by an industrial-grade motor engineered for durability and thermal efficiency, the R25 delivers a sustained 25Nm of torque without throttling—ideal for professional-grade sim racing and extended endurance sessions.
21-bit Magnetic Encoder
With a 21-bit high-resolution magnetic encoder, the R25 delivers over 2 million points of precision, capturing every steering input and surface detail with stunning accuracy. Connect with the road like never before.
Refined Design with RGB Customisation
Designed with a compact, motorsport-inspired profile, the R25 looks as serious as it performs. Dual RGB light strips along the top edges offer 16.7 million colours and fully customisable lighting effects, including real-time telemetry feedback for ABS, traction control, gear shifts, and flag signals.
New Force Feedback Algorithm
The powerful R25 DD base pairs seamlessly with MOZA’s advanced Nexgen 4.0 Force Feedback Algorithm, combining cutting-edge hardware and software. This synergy delivers more realistic force feedback and enables precise tuning tailored to every driving style.
Fully Customisable via MOZA Pit House Software
MOZA Pit House software gives racers total control over FFB behaviour:
• Force Feedback Curves: Choose from preset profiles or create your own.
• Force Interpolation: Smooths out granular effects for finer detail in surface feedback.
• Advanced Tuning: Independently adjust spring, damper, and friction forces without affecting vibration or game-based effects—ideal for serious users who demand full tuning control.
Intelligent Thermal Management
The R25 features MOZA’s fully upgraded intelligent cooling system providing ample motor headroom and optimised thermal efficiency, it runs cooler—even under sustained high torque. Real-time temperature monitoring and smart torque regulation work together to maintain peak performance through the most demanding racing sessions.
Versatile Mounting Options
Supports bottom, front, and side mounting to accommodate a wide range of rigs.
CNC-machined Aluminium Housing
Constructed from a rigid die-cast aluminium unibody, the R25 offers exceptional structural integrity and torsional rigidity—essential for withstanding high-torque output—while keeping overall weight to a minimum.
Native Ecosystem Integration
Featuring dedicated ports for all major MOZA peripherals, the R25 keeps your setup clean and hassle-free—simply plug in pedals, shifters, dashboards, or a handbrake without the need for extra USB hubs or cables.
Extreme Durability
Built for endurance and performance, MOZA’s slip ring handles over 10 million rotations and transfers data at 2M/s, delivering solid connection and lag-free communication between the wheel and base.
