MOZA R16 Ultra
The R16 Ultra is the R16 reworked into the Ultra line: same 16 Nm sustained torque, but with a new ultra-low-cogging flat-wire motor, a 600 MHz processor and the NexGen U1 algorithm, in a much more compact chassis (206 mm long). Like the rest of the Ultra line, it is rated by SUSTAINED torque, not peak.
MOZA R16 UltraMOZA R21 Ultra
The R21 Ultra is the full redesign of MOZA’s high end: 21 Nm of sustained torque driven by a next-generation zero-cogging flat-wire motor that minimises cogging for a cleaner, more powerful and more detailed FFB. It has a 21-bit encoder, 1000 Hz USB refresh, intelligent thermal management with real-time torque regulation and premium construction. It is aimed at those seeking maximum force detail on PC. In Automobilista 2 it shines in high-downforce single-seaters, prototypes, hypercars and competitive-level GT3, where the extra torque and motor smoothness make the difference.
