The Specs: On Paper

The Moza R21 Wheel Base outperforms its counterpart, the Moza R12, in one crucial aspect: torque. With 21Nm of torque at your disposal, you'll be able to harness more precise control and immersive feedback. The R21 maintains a premium price point but is worth considering if you're serious about sim racing.

The Ugly Truth (Real User Experience)

I've seen users struggle with the Moza R12's FFB dropping significantly after prolonged gaming sessions, often to as low as 50% of its intended strength. The base may not be warm, so it's not thermal throttling – it's either a faulty temp sensor or an inherent design flaw. And don't even get me started on the 'improved' rev light strip that's more of a distraction than anything else.

The R12 has been plagued by issues ranging from overheating to broken Quick Releases. I've heard tales of users receiving faulty units, only to have them replaced with another defective one. The lack of support from Moza's customer service is staggering. One user's solution was to change the PCB, which should not be a common occurrence in any sim racing wheel.

On the other hand, I've seen no significant issues reported for the R21 – yet. A few users have mentioned notchiness when powering down, but that's expected and can't be considered a design flaw. The real question is: how long will it last?

The Verdict

If you're looking to upgrade from an entry-level wheel or are new to sim racing, the Moza R12 may seem like a good value for money due to its more affordable price point. However, if I had to choose between these two – and I do – the Moza R21 wins hands down.

For those who can afford it, the R21 offers unmatched torque and performance. Its premium price is justified by the quality and reliability users have come to expect from direct drive wheels. It's not perfect, but if you're serious about sim racing, the R21 should be your top choice – just don't say I didn't warn you about Moza's customer support.
