MOZA R21 Ultra (21 Nm)
The R21 Ultra is a pro direct-drive base producing 21Nm of peak torque on the MOZA-QR mount, marking it as serious competition-grade hardware. It's built for PC sim racers who want sustained-torque headroom for league and competitive driving. It demands a rigid aluminum-profile cockpit, so tube-frame or desk-clamp setups won't safely contain this much force.
