MOZA Racing has officially introduced the R25 Ultra wheelbase, positioned at the top of its ecosystem as a high-torque solution for serious sim racers. Delivering a sustained 25 Nm of peak torque, the new motor design aims for ultra-smooth feedback with a zero-cogging structure for consistent rotational force. The base also includes an integrated high-precision torque sensor running at up to 2 kHz for accurate force reproduction, giving drivers detailed feel during cornering, curb impacts, and grip transitions.
Built around a 21-bit magnetic encoder offering over 2 million points of resolution, the R25 Ultra is engineered for steering accuracy during competitive racing. Its CNC-machined aluminum body provides rigidity under load and includes multi-position mounting for cockpits using front, side, or bottom brackets. Thermal stability is managed by an intelligent cooling system to maintain performance in endurance sessions. The R25 Ultra also features programmable RGB side lighting that can act as a telemetry display for revs, traction control, ABS and warnings. Connectivity is another focus: direct ports are built in for MOZA shifters, pedals, dashboards and handbrakes, minimizing USB dependency and simplifying cable management.
The R25 Ultra enters the market as a direct challenge to established high-end direct drive bases, bringing premium torque levels and industrial-grade engineering at a competitive price point. With tight software integration through MOZA Pit House and compatibility across the full MOZA ecosystem, it targets sim racers upgrading from mid-range DD bases who want more headroom, realism, and tuning flexibility without stepping into extreme professional hardware pricing.
