MOZA R16 Ultra Direct Drive Wheelbase
The MOZA R16 Ultra is a next-generation direct drive wheelbase that brings the flat-wire motor technology from MOZA's flagship R21 Ultra and R25 Ultra down to the 16Nm tier. It replaces the R16 V2 with a fundamentally new motor, a refined CNC-machined aluminium chassis, and dual RGB telemetry strips, making it the most significant generational step in the MOZA Racing R16 line since its original release.
The core change over the R16 V2 is the motor itself. Where the V2 used a conventional slanted-pole servo motor and quoted 16Nm as a peak figure, the R16 Ultra uses an all-new zero-cogging flat-wire motor and rates 16Nm as constant torque — output that holds throughout the full session under any thermal load. That shift, combined with the NexGen Force Feedback Algorithm U1 and a 600MHz CPU, produces a sim racing wheelbase that communicates more detail, more smoothly, and more consistently than the hardware it replaces.
The R16 Ultra sits at the entry point of MOZA's Ultra motor architecture. Drivers who want the zero-cogging flat-wire feel without stepping to the 21Nm output of the MOZA R21 Ultra will find the R16 Ultra covers the full range of sim racing disciplines at 16Nm constant. All configuration runs through MOZA Pit House, which manages the wheelbase, pedals, shifter, and dashboard from a single interface.

How the MOZA R16 Ultra compares to other direct drive wheelbases
Most direct drive wheelbases in the 12–16Nm range use conventional round-wire servo motors with slanted-pole rotor designs. These motors work well, but they introduce a degree of cogging — a subtle magnetic resistance that varies with rotor position and creates a faint stepped or notchy feeling at low shaft speeds. Under hard force feedback it is largely masked, but in slow corners, hairpins, and at the centre of the steering arc it can interrupt the smoothness of what you feel through the wheel. Most drivers accept it as normal because it has been the standard across direct drive hardware for years.
The R16 Ultra uses a flat-wire motor that near-eliminates cogging by reducing stator slot size. The steering arc feels uniformly smooth regardless of speed, and force feedback signals are reproduced without the interference of cogging in the signal.
Flat-wire motor construction also achieves higher torque density for a given motor size and dissipates heat more efficiently, which is why the R16 Ultra can rate 16Nm as constant rather than peak. Compared to the MOZA R12 V2, the R16 Ultra adds 4Nm of constant torque, the Ultra motor architecture, NexGen U1 algorithm, RGB telemetry, and a redesigned CNC chassis.
Drivers who want more torque headroom above the R16 Ultra can step to the MOZA R21 Ultra, which shares the same flat-wire motor technology at 21Nm constant.
Smooth, cogging-free force feedback from the flat-wire motor
Cogging in a conventional direct drive motor comes from the magnetic attraction between the motor's rotating components and the iron in its stator. As the shaft turns slowly, that attraction creates resistance that varies with position, producing a faint but perceptible stepped feeling through the wheel. The R16 Ultra's flat-wire motor reduces stator slot size significantly, near-eliminating cogging and producing a rotation that is smooth at any speed and in any direction.
The practical benefit is that finer force feedback details are reproduced more accurately. The texture of a rumble strip, the progressive load through a long radius corner, and the gradual release of grip at the limit all arrive through the wheel without cogging interference. Flat-wire windings also offer better heat dissipation than conventional round-wire construction, which feeds directly into the R16 Ultra's constant torque rating and long-session consistency.
16Nm constant torque that holds throughout the full session
A sim racing wheelbase that quotes peak torque delivers that output only under optimal thermal conditions. As the motor heats over a session, output is reduced to protect the hardware. The R16 Ultra's 16Nm constant torque rating means the base sustains full output continuously, with the flat-wire motor's efficient heat dissipation and intelligent thermal management working together to hold performance without backing down mid-session.
For most sim racing disciplines, the difference between constant and peak torque is most noticeable in longer sessions and endurance formats. Drivers running hour-long stints, endurance championships, or extended practice runs will feel the difference between a base that holds its rated output and one that doesn't. The R16 Ultra's 600MHz CPU also handles NexGen U1 algorithm calculations with lower latency than previous MOZA hardware, contributing to the responsiveness of force feedback delivery across the full session length.
RGB telemetry and motorsport-inspired design
The R16 Ultra features dual RGB light strips running along the top edges of the CNC-machined aluminium housing. Each strip supports 16.7 million colours and is configurable through MOZA Pit House as static lighting, dynamic colour effects, or real-time telemetry display. Telemetry mode signals ABS activation, traction control intervention, gear change prompts, and flag conditions through the strips, giving trackside information at a glance without looking away from the racing line.
The CNC-machined aluminium housing adopts the compact, motorsport-inspired form factor introduced across the R21 Ultra and R25 Ultra, departing from the two-tone supercar design of the R16 V2. Mounting options cover bottom, front, and side positions to suit GT cockpits, formula-style rigs, and desk setups with an optional clamp, and the housing's rigidity holds alignment under sustained high-torque steering inputs.
Pit House integration and MOZA ecosystem connectivity
The R16 Ultra connects to your PC via a single USB cable and pairs with the full range of MOZA steering wheels through wireless quick release. MOZA Pit House handles all wheelbase and peripheral configuration from one interface, covering force feedback strength and curve shape, the FFB equalizer, game FFB decoupling, road feel settings, button mapping, and RGB lighting profiles. iRacing users can enable 360Hz force feedback mode for higher-resolution signal delivery during rapid changes in tyre grip and load transfer.
Direct ecosystem integration ports on the wheelbase allow MOZA pedals, shifters, handbrakes, and digital dashboards to connect without occupying additional PC USB ports. All connected devices operate simultaneously through the single PC connection. Firmware updates are delivered through Pit House automatically, and per-title game profiles save your preferred force feedback configuration for each sim so you can launch directly into a calibrated setup.
Frequently Asked Questions
What is the difference between the R16 Ultra and the R16 V2?
The R16 Ultra replaces the R16 V2 with a fundamentally different motor. The V2 used a conventional slanted-pole servo motor and quoted 16Nm as a peak torque figure. The R16 Ultra uses a zero-cogging flat-wire motor that maintains 16Nm as a constant torque output throughout the full session. The R16 Ultra also adds the NexGen U1 FFB algorithm, dual RGB telemetry strips, a 600MHz CPU, and a redesigned CNC aluminium chassis.
What does zero-cogging mean and why does it matter for sim racing?
Cogging is the subtle magnetic resistance caused by the attraction between the rotating and stationary parts of a conventional direct drive motor. It creates a faint stepped or notchy feeling at low shaft speeds that can interfere with smooth force feedback. The R16 Ultra's flat-wire motor near-eliminates cogging, producing a steering feel that is smooth and consistent across the full rotation range. It also allows finer force feedback details to be reproduced more accurately since the cogging interference is removed from the signal.
What is the difference between constant torque and peak torque?
Peak torque is the maximum output a wheelbase can deliver for short periods under ideal thermal conditions. As the motor heats during a session, output is typically reduced to manage temperature. Constant torque is the output a base can sustain continuously. The R16 Ultra's 16Nm constant rating means it holds full output throughout an extended session, which matters most for endurance stints and back-to-back practice runs.
How does the R16 Ultra compare to the MOZA R21 Ultra?
Both share the same zero-cogging flat-wire motor technology, 21-bit encoder, NexGen U1 algorithm, and dual RGB telemetry. The R21 Ultra delivers 21Nm of constant torque versus 16Nm on the R16 Ultra. The additional torque on the R21 Ultra is most noticeable at the limit in high-load corners and during aggressive driving inputs. The R16 Ultra is the more accessible entry point into the Ultra motor architecture.
How does the R16 Ultra compare to the MOZA R12 V2?
The R12 V2 delivers 12Nm using a conventional servo motor with NexGen 4.0 FFB. The R16 Ultra adds 4Nm of constant torque, the zero-cogging flat-wire motor, NexGen U1 algorithm, RGB telemetry, and a 600MHz CPU. The R16 Ultra represents a step up in both torque output and underlying motor technology over the R12 V2.
What MOZA wheels are compatible with the R16 Ultra?
The R16 Ultra is compatible with the full range of MOZA steering wheels via MOZA's wireless quick release system.
Can I connect my existing MOZA pedals, shifter, and handbrake directly?
Yes. The R16 Ultra features direct connection ports for MOZA pedals, shifter, handbrake, and digital dashboard, allowing all peripherals to operate through the single USB PC connection without additional hubs.
