The Specs: On Paper

The Moza R21 comes out on top in terms of torque, with a whopping 12Nm more than its younger sibling. It's clear that Moza is pushing the boundaries of what's possible with direct drive technology.

The Ugly Truth (Real User Experience)

I've seen users struggle with both wheels, but for different reasons. The R9 V2 has had issues with overheating and FFB loss, which can be frustrating to deal with. I've heard of people experiencing idle oscillation, which sounds like a nightmare to fix. The good news is that Moza seems to have addressed these problems in newer batches. However, users are still reporting some minor issues, such as the wheel feeling notchy when not connected to a steering wheel. On the other hand, the R21 has had its own set of problems, including random freezing and issues with the PCB. But here's the thing: Moza seems more willing to help users troubleshoot these issues, even going so far as to replace the PCB in some cases. I've heard horror stories about customer service from other manufacturers, but Moza seems to be taking a more proactive approach. The big problem here is that both wheels have their own set of quirks and flaws. But if I had to choose, I'd say the R21 has it slightly worse off. The freezing issue in particular sounds like a major pain to deal with, especially considering how expensive this wheel is.

The Verdict

So who gets my money? In a perfect world, I'd recommend the Moza R21 for its superior torque and more aggressive direct drive feel. But let's be real: it's not a perfect product, and users will have to deal with some minor issues. If you're on a budget or just starting out in sim racing, the Moza R9 V2 is still a solid choice. It may not have the same level of torque as its bigger brother, but it's more affordable and still offers an excellent driving experience. However, if I had to choose for myself, I'd say go with the R21 – despite its flaws. The driving feel is just that good, and Moza seems committed to supporting users through any issues they may have. Just be prepared for a premium price point and some minor headaches along the way.
