Moza launches all-new R21 and R25 range-topping sim racing wheel bases

• Moza Racing replaces its first-ever sim racing wheel base with two all-new models

• The 21Nm R21 Ultra DD and the 25Nm R25 Ultra True Torque DD
• Both use an all-new force feedback motor, encased in a new outer shell
• Only the R25 has a torque sense for quicker reactions
• Pricing looks to be extremely competitive for the specifications

Moza Racing has filled the sim racing equipment market with entry-level devices, high-end steering wheels with round screens in the middle and even a force feedback gear shifter.

But now it is time to circle back to the beginning, as it’s time for its first-ever wheel base, the R21, to be replaced. Launched in 2021 alongside a lower-power R16, and then receiving a V2 update in 2023, these have now been superseded by the R21 Ultra DD Wheel Base (21Nm of torque) and R25 Ultra True Torque DD Wheel Base (25Nm of torque).

These are all-new designs, inside and out. They both include what Moza touts as a “next generation flat-wire” force feedback motor, which, as is the trend with current offerings from the likes of Thrustmaster, Simagic and PXN, promises “zero coggging”.

This is a phenomenon where you could feel ‘steps’ in a force feedback system, so a setup designed to avoid such sensations, on paper, should deliver smoother performance.

The Chinese sim racing giant also claims that the R25 has the quickest torque response, at least 10Nm per millisecond (torque slew rate), in the entire industry – for comparison, a Simucube 2 Pro is rated at 8.0 Nm/ms and the Asetek Invicta at 9.4 Nm/ms.

This is paired with a 21-bit magnetic encoder and the existing (all current Moza wheelbases use it) Nexgen 4.0 Force Feedback Algorithm.

Outside, you have a dramatic change in design, with a CNC-machined aluminium housing with customisable RGB lighting/ This can be programmed to match real-time telemetry feedback, for example, changing colour when shifting gears, hitting the ABS system or race flag signals.

Perhaps the biggest shift is the ultra-competitive pricing. The all-new R21 Ultra DD kicks off at $699, compared to the existing R21’s $849. The R25 Ultra True Torque DD, meanwhile, will cost $899, which noticeably undercuts rival devices at similar peak torque outputs.

On paper, this seems to be a significant moment for high-end wheel bases, although we’ll have to test it first to see if it matches up to the specifications, and rival manufacturers are unlikely to stand still.
