R21 Wheel Base
With 21Nm of peak torque—30% more than similar models—the R21 V2 delivers ultra-precise, immersive racing powered by a carbon-slanted pole servo motor. A triple-staggered rotor design ensures smooth, vibration-free operation, while a 21-bit encoder and 280MHz processor accurately capture every movement. Wrapped in a sleek aluminum body and tuned via the MOZA Pit House App, it’s built for serious racers.
