Best Decision Ever

I recently moved from the logitech ecosystem to Moza. The R21 wheel base is a serious piece of hardware. Coupled with the Moza pithouse software it's phenomenal. The R21 is definitely professional quality hardware. Just make sure it is mounted firmly. The R21 is a beast!
I have mine mounted to a free standing base, I built myself. The base is independent of my desk, making sure it doesn't touch the desk were my monitors are. I have the mount anchored to the wall. During heavy FFB, it literally shakes picture frames hanging. That's even when I'm only using 85 percent torque. I don't even have it turned up completely. Coupled with the software, the FFB is simply astonishing. If your not sure about the R21, don't hesitate. You won't be disappointed

Moza R21 what an upgrade for me not looked back since owning it

Well i took the plunge and upgraded to the R21 wheelbase and my god it makes driving sims a lot better don’t need full FFB but you feel the track and tyres gripping and would recommend it.

More strength than I'll likely ever need

Recently upgraded from my R9 wheelbase - I loved its strength, but when applying steering lock through a fast corner I was hitting the maximum feedback and not getting any more detail through the turn. The R21 has been a fantastic upgrade and I don't lose any detail. The level of force is very satisfying and provides a convincing connection to the car even with the feedback dialed down to 50%. The base runs much cooler than my R9 did and looks very sleek. It's hard to imagine that I'll ever want to upgrade from this wheelbase and I'd recommend it to any sim racer with a solid rig to mount it on.

Best in Class Racing gear at an affordable price

I wanted to upgrade from the Moza R12 to the best experience that Moza had to offer and that was the Moza R21. The build quality on this Direct Drive Wheel is so unique and stylish that you want to show it off. 21nm of torque is plenty for what I need and using the Moza Pithouse software to adjust what I wanted was a breeze! I would definitely buy from Moza again and I recommend the Moza R21 in 2025!
