MOZA R21 Ultra Direct Drive Wheel BasevsSimucube 2 Sport Direct Drive Wheelbase

The Bottom Line

The choice between the MOZA R21 Ultra Direct Drive Wheel Base and the Simucube 2 Sport Direct Drive Wheelbase comes down to a battle of raw, budget-friendly power versus premium, highly refined force feedback. While MOZA targets maximum torque per dollar, Simucube focuses on industry-leading detail and software sophistication.

Watch out

MOZA users have reported failed firmware updates that can temporarily leave the R21 unresponsive or completely strip its force feedback. Additionally, some software updates have broken force feedback detail, requiring users to manually disable the 'Hands Off Protection' setting to restore it.

Note

The Simucube SQR quick release does not integrate power or data transfer, meaning you must use batteries for wireless wheels or run coiled USB cables for wired ones. Furthermore, the SQR system requires a physical locking pin and can fit so tightly that it occasionally gets stuck, requiring significant force to unmount.

Why choose MOZA R21 Ultra Direct Drive Wheel Base

8.2
Performance
  • Unbeatable Value and Power: It delivers a massive 21 Nm of peak torque and 2700 degrees of maximum rotation at a highly competitive price point.
  • Flexible Mounting: It supports bottom, side, and front mounting, offering far more installation flexibility than its competitor.

Why choose Simucube 2 Sport Direct Drive Wheelbase

8.5
Performance
  • Lighter Weight: At 8 kg, it is lighter than the 9 kg MOZA base, reducing the load on your rig's front mount.
  • Superior Software Ecosystem: The True Drive software provides industry-leading force feedback detail, deep tuning, and cloud-based profile sharing via the True Drive Paddock.

The Verdict

If you want the absolute most torque for your dollar and versatile mounting options, the MOZA R21 is an incredibly powerful option. However, if you prioritize software stability, industry-leading force feedback detail, and a lighter wheelbase, the Simucube 2 Sport justifies its premium price tag.
