MOZA 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.
MOZA R21 UltraMOZA R25 Ultra
The R25 Ultra is MOZA’s most powerful base, with 25 Nm of sustained torque and the same zero-cogging flat-wire motor of the Ultra range, here with 26% more torque density than similar-sized rivals. A 21-bit encoder, 378 W of power, improved thermal management with real-time monitoring and premium chassis round off a flagship aimed at enthusiasts and semi-pro use. It delivers enormous force with a smoothness that avoids clipping even at maximum. For Automobilista 2 it is overkill for most, but it is the ultimate choice for high-end formula and prototypes where you want to feel every last detail.
