MOZA Racing
MOZA R21 Ultra + KS Pro Steering Wheel Bundle
The MOZA R21 Ultra + KS Pro Steering Wheel Bundle combines MOZA's 21 Nm sustained-torque wheel base with a compact 300 mm butterfly-style GT wheel. The base provides high-force direct drive, a 21-bit magnetic encoder and intelligent thermal management, while the KS Pro adds a 2.99-inch configurable display, a dense programmable control layout and forged-carbon dual-clutch paddles. Together they form a PC racing system for GT, formula, prototype and endurance simulation, ready to mount to a suitable high-strength cockpit.
Why choose this product?
- The R21 Ultra delivers sustained 21 Nm torque from a zero-cogging flat-wire motor, giving the KS Pro detailed force feedback during both short races and long endurance sessions.
- The 300 mm KS Pro combines a customisable HD display, extensive programmable inputs, dual-clutch paddles and RGB telemetry for fast in-car adjustments.
Bundle components
R21 Ultra direct-drive base
The R21 Ultra uses a next-generation flat-wire direct-drive motor rated at 21 Nm sustained torque. A 21-bit magnetic encoder resolves 2,097,152 positions per revolution, supported by a 1000 Hz USB refresh rate and MOZA's current force-feedback algorithm. The base also supports iRacing's published 360 Hz mode, allowing higher-frequency feedback where the title and configuration permit.
KS Pro steering wheel
The included KS Pro is a 300 mm butterfly-style GT wheel with TPE grips and a carbon-fibre-reinforced composite structure. Its 2.99-inch HD display supports configurable dashboards through MOZA Pit House. The front and rear layout includes ten RGB buttons, five rotary encoders, two thumb encoders, two seven-way switches, two rear buttons, twelve rev LEDs and six flag LEDs.
Paddles and quick release
Magnetic forged-carbon shifter paddles use Hall sensors for repeatable actuation, while the dual-clutch paddles support launch, single-clutch or programmable operating modes. The all-aluminium quick release connects directly to the R21 Ultra, and communication passes through the conductive connection without a loose external wheel cable.
Mounting, power and connections
The R21 Ultra supports front, side and bottom mounting and requires a rigid cockpit or bracket suitable for 21 Nm direct drive. The base is powered through the included 360 W power system and provides rear ports for compatible pedals, dashboard, shifter, handbrake and an optional emergency-stop switch. Pedals, cockpit hardware and the emergency stop are not included.
Software and configuration
MOZA Pit House is used to update firmware, calibrate steering, set force-feedback filters, configure steering angle, customise the display and assign the wheel's controls. RGB rev, flag and button lighting can be linked to supported telemetry. The supported mobile app provides additional base-adjustment options without changing the physical control layout.
Upgrade options
The bundle can be expanded with compatible MOZA pedals, shifters, handbrakes and dashboards through the wheel-base ports or separate PC connections. Because these additions depend on the intended racing discipline and are not part of the standard package, they must be selected and mounted separately.
Compatibility
Platform: Windows PC.
Connection and ecosystem: the KS Pro is directly compatible with the included R21 Ultra through the MOZA quick release and conductive communication system.
Requirements: a rigid high-torque cockpit or mounting bracket is required. Pedals and other driving controls are not included.
