MOZA R25 Ultra 25Nm Direct-Drive WheelbasevsSimucube 3 Ultimate WheelBase

The Bottom Line

The MOZA R25 Ultra 25Nm Direct-Drive Wheelbase offers high-end torque at an aggressive mid-range price, while the Simucube 3 Ultimate WheelBase targets ultra-enthusiasts with massive power. Choosing between them is a battle of raw value versus uncompromising, high-fidelity performance.

Watch out

The Simucube 3 Ultimate suffered a rough launch with early FFB knocking, EMI interference, and control box signal noise. Meanwhile, the MOZA R25 Ultra can feel vague and disconnected out of the box if you enable Hands-Off Protection, requiring extensive tuning to recover road texture sensitivity.

Note

Simucube's proprietary ecosystem lacks USB passthrough and forces you into expensive proprietary quick releases. Conversely, MOZA uses a standard D1-Spec quick release and offers more versatile mounting options, though some users report minor hole spacing mismatches on certain rigs.

Why choose MOZA R25 Ultra 25Nm Direct-Drive Wheelbase

8.5
Overall Score
  • Offers superior physical flexibility with a lighter 9.1 kg chassis, 2700 degrees of maximum rotation, and versatile bottom, front, and side mounting options.
  • Delivers exceptional rotational smoothness under heavy loads thanks to its highly praised zero-cogging flat-wire motor, all at a highly competitive price of $877.67.

Why choose Simucube 3 Ultimate WheelBase

8.8
Overall Score
  • Boasts a massive 35 Nm of peak torque, utilizing an IPM motor that delivers incredibly refined, crisp, and detailed force feedback even when dialed down.
  • Features the advanced contactless LightBridge quick-release system, providing seamless wireless power and data to your steering wheels.

The Verdict

If you want maximum detail, unmatched 35 Nm power, and have $3,299.00 to spend, the Simucube 3 Ultimate is the premium choice despite its closed ecosystem. However, for most drivers, the MOZA R25 Ultra at $877.67 offers a far more practical, highly adjustable, and budget-friendly path to high-torque direct-drive racing.
