Powerful direct drive experience

The R21 Ultra combines a 21 Nm high-performance motor with an industrial design for maximum continuous performance. Even during long endurance races or intensive training, the base delivers constant power without any loss of performance. Every input is transmitted precisely, so that every cornering line and every braking point can be felt directly.

Precision down to the last detail

Thanks to the 21-bit magnetic encoder, the R21 Ultra captures over 2 million data points to reproduce every steering wheel movement with millimeter precision. The result: an extremely realistic simulation in which every bump in the road, every change of surface and every reaction of the vehicle is transferred perfectly to your hands.

Intelligent design and RGB customization

The compact, motorsport-inspired aluminum housing offers maximum torsional rigidity and a durable structure with minimal weight. Dual RGB light strips on the upper edges can be individually programmed with 16.7 million colors - including real-time telemetry for ABS, traction control, gear changes or flag displays. The R21 Ultra thus combines functionality with a stylish racing look.

Optimized cooling and safety

The R21 Ultra has intelligent thermal management that keeps the engine cool, even under maximum torque. With hands-off protection, the system detects when hands are removed from the steering wheel, safely stops any movement and automatically centers the wheel. Together with the extremely durable slip-ring technology, this ensures reliable, long-lasting performance without delay.
