MOZA R25 Ultra Direct Drive Wheel BasevsR5 Wheel Base

The Bottom Line

The MOZA R25 Ultra and the MOZA R5 represent the absolute opposite ends of the direct drive spectrum, pitting a brutal 25 Nm flagship powerhouse against a tiny, budget-friendly 5.5 Nm entry-level base. Choosing between them isn't just about budget; it is a choice between a permanent, heavy-duty cockpit centerpiece and a compact starter kit.

Critical Warning

The MOZA R5 is notorious for running extremely hot during extended racing sessions, with some users reporting a faint burning smell and thermal throttling that noticeably drops your force feedback. Additionally, its non-standard 78.7mm x 40mm bottom mounting pattern means you will likely need an adapter plate to bolt it to standard cockpits.

Pro Tip

If you plan to run the MOZA R25 Ultra dialed down to mid-range torque (around 10–14 Nm), be aware that some drivers report a slightly muted, less lively feedback profile compared to dedicated mid-range bases. Also, the lack of a USB passthrough on the base means third-party steering wheels will require a separate coiled cable running directly to your PC.

Why choose MOZA R25 Ultra Direct Drive Wheel Base

9.2
Performance Rating
  • Massive 25 Nm peak torque provides endless headroom, preventing any clipping even under the most demanding physics loads.
  • The integrated true torque sensor and flat-wire motor deliver incredibly detailed, smooth, and precise road texture feedback.
  • Highly versatile mounting options (bottom, front, and side) make it easy to integrate into any high-end aluminum profile rig.

Why choose R5 Wheel Base

7.4
Performance Rating
  • Extremely accessible price point makes it one of the cheapest entry points into the direct drive ecosystem.
  • Ultra-compact form factor is perfect for desk clamps or small, space-constrained wheel stands.
  • Delivers surprisingly smooth and detailed feedback for its 5.5 Nm size when kept within its thermal limits.

The Verdict

If you have a rigid cockpit and the budget, the MOZA R25 Ultra is a stellar flagship that offers incredible detail and endless headroom despite its minor ergonomic quirks. However, if you are just starting out or space is tight, the MOZA R5 remains a highly capable entry-level option, provided you manage its heat and mount it properly.
