Moza Wheelbase Torque Explained: R5 vs R9 vs R12 vs R16 vs R21 vs R25 and Which One You Need

Torque numbers get thrown around a lot across Moza's wheelbase lineup, and it's easy to assume more Newton-metres always means a better setup. It doesn't. The right wheelbase depends on your rig, your discipline, and how much force your wrists want to fight through a three-hour stint. Here's what separates the R5, R9, R12, R16, R21, and R25 so you can match torque to your rig.

What the Torque Number Tells You

This Moza direct drive wheelbase comparison breaks down peak vs sustained Nm across the range.

Peak torque is a ceiling: the maximum force the motor can push for a split second, such as slamming into a kerb or catching a snap of oversteer. It isn't what you feel lap after lap. That's why the R21 Ultra lists its 21 Nm rating as sustained rather than peak, holding that output through a full endurance stint without throttling back to manage heat, while the R9 and R12 quote maximum figures under standard peak-torque testing. Two wheelbases with similar numbers on paper can behave very differently once a session runs long.

R5 Pro, 6 Nm

The R5 Pro is Moza's most popular entry-level bundle into direct drive. We sell it as a complete bundle with the ES Lite wheel and SRP Lite2 pedals rather than as a standalone base, from $899.99. At 6 Nm, with a 21-bit encoder and Moza's NexGen Force Feedback Algorithm 5.0, it makes the jump from a belt or gear-driven wheel feel immediate through kerb strikes and weight transfer under braking. It suits desk-clamp setups and smaller rigs well, and stays compatible with the wider Moza wheel range for a later upgrade.

R9 V3, 9 Nm

Step up to the R9 V3, from $749.99, and you're working with 9 Nm from a purpose-built servo motor at 180W peak power, plus support for iRacing's 360Hz protocol. It's the base a lot of intermediate racers land on: strong enough for GT3 and open-wheel titles, without demanding the rig the higher-torque bases prefer. For most people who have outgrown a belt-driven wheel, this is where the upgrade path stops.

R12 V2, 12 Nm

The R12 V2, from $949.99, runs Moza's NexGen 4.0 force feedback algorithm through a 12 Nm motor rated at 216W peak power. The extra headroom shows up as more resolved detail through kerbs, road texture and tyre slip, rather than raw resistance alone. Hand-off Protection detects when your hands leave the wheel and centres it automatically, which matters more at this torque level. Pair it with a stiff cockpit and load cell pedals, and it holds its own against setups above its…
