MOZA R25 Ultra – Direct Drive Wheelbase with 25 Nm Continuous Torque and Integrated Torque Sensor

The MOZA R25 Ultra is the current flagship wheelbase from MOZA Racing, delivering 25 Nm of continuous torque via a cogging-free flat-wire motor. For the first time in the MOZA lineup, a true torque sensor is integrated, capturing steering inputs with 0.1% measurement accuracy and up to 2 kHz sampling rate. The 21-bit magnetic encoder with 2,097,152 PPR and the new NexGen Force U1 FFB algorithm complete the package. The housing and coupling are made of die-cast aluminum; mounting is possible at the bottom, front, and sides.
