What it is
The R25 Ultra is the most powerful base in Moza’s catalogue. You get 25 Nm of sustained torque from the new flat-wire zero-cogging motor, a 21-bit encoder, the True Torque closed-loop sensor architecture, and the standard Moza QR that runs across the whole R-range. It’s PC-only, like the rest of the Moza line - there’s no console licensing on any Moza base, so if you race on Xbox or PlayStation this isn’t your wheelbase.
For me the R25 Ultra is the base that settles the argument: Moza is back at the high end, and the Ultra hardware is what turned the R-range from a value play into a serious flagship. Every long-form reviewer I’ve read landed in the same place, which doesn’t happen often at this torque tier.
What you’re paying for over the R21 Ultra is 4 extra Newton-metres of peak torque and the True Torque sensor, which holds a flatter, more accurate curve at the top of the envelope. Whether that matters comes down entirely to what you race.
Who it’s for
You’re the right buyer if you race PC, you want the most torque-per-pound on the market, and you don’t want to give up build quality or software polish to get it. The R25 Ultra is the only 25 Nm base in its price tier, and the gap to Simucube and Asetek on price is wide enough that the sums tilt hard in Moza’s favour for anyone who isn’t specifically chasing software depth.
You’re the right buyer if you race endurance, prototype or heavy formula. This is where 25 Nm shows up - the loaded moments at the limit of an LMP car at full stiffness, the kerbs that clip a 16 Nm base, the long stints where thermal headroom matters. The Ultra chassis runs cool, and the True Torque sensor keeps the curve accurate under heavy load.
You’re the wrong buyer if you race on console. The R25 Ultra is PC-only, and so is every other base Moza makes - there’s no Xbox or PlayStation licensing anywhere in the catalogue. Xbox drivers who want a real flagship are looking at Fanatec’s Podium or ClubSport DD line through an Xbox-licensed rim; PS5 drivers have only the 8 Nm Fanatec GT DD Pro.
You’re the wrong buyer if your usual diet is GT3 and road cars. Those cars don’t ask for more than 12-16 Nm, and the extra headroom on the R25 Ultra is insurance for cars you probably don’t drive most weeks.
In use
25 Nm of sustained torque is the kind of authority that changes how you drive. What I noticed first was the stability under load - it doesn’t flinch under heavy FFB at the limit of an LMP car, and it delivers clean peaks without the slight pinch mid-tier bases show. That’s what earns the flagship label. Slip arrives smooth, kerbs come through with proper texture, and the long corners build load in a way that keeps a long stint feeling steady rather than tiring.
The flat-wire zero-cogging motor is the other headline. The off-centre signal is noticeably cleaner than the older R21 motor, and the gap to Simucube on smoothness has narrowed a lot. It’s not all the way closed - Simucube’s True Drive still wins on signal polish at the absolute edge - but the difference is now small enough that most drivers won’t pick it out in normal racing.
Pit House does the tuning. It’s comfortably ahead of where it was at the original R-range launch - the per-title presets are broad and the macro controls are intuitive. Not as deep as True Drive, but a real tool now, and deep enough for most of us.
Thermal behaviour is the other thing that matters at this torque tier. The R25 Ultra runs cool through long stints in a way 16 and 21 Nm bases don’t, and that headroom is the difference between iRacing endurance work feeling settled and feeling like the base is fading at hour three.
What to watch out for
The firmware regression on Hands-Off Protection Mode 2 is the documented issue. Toggling the mode off in Pit House restores the expected behaviour, and Moza is working on a fix. Not a deal-breaker, but worth knowing.
The platform limit is the thing to be clear about. The R25 Ultra is PC-only, and Moza has no console licensing on any base, so there’s no Xbox or PlayStation route here at all. If you need a console-capable flagship, you’re shopping Fanatec, not Moza.
True Drive is still the deepest tuning software in the category, and Pit House hasn’t closed that gap. If software depth is the thing you care about most, Simucube is still the right answer. For everyone else, Pit House does the job.
Where it sits in 2026
At $899 direct from Moza (some resellers list it nearer $980, and UK retail runs higher once VAT is in, so treat any FX-derived GBP as approximate) the R25 Ultra sits in the most price-sensitive part of the flagship market. The rival shopping list is short and the answer depends on what you want from a flagship.
Against the in-house R21 Ultra at around $699, the R25 is roughly $200 more (about ~£160 at FX) for 4 extra Newton-metres and the True Torque sensor. The R25 earns the premium when you race heavy LMP or formula at full FFB regularly. For most drivers, the R21 Ultra is the more rational top of the Moza line.
Against the Simucube 2 Pro at around €1,073 manufacturer (25 Nm), the R25 Ultra still undercuts it by a clear margin at the same torque peak. Simucube wins on True Drive software depth, on signal smoothness at the absolute edge, and on the six-year long-term ownership signal. The R25 Ultra wins on price, on the newer motor and sensor architecture, and on the bundled Moza catalogue above and below the base. For PC-only buyers who aren’t wedded to Simucube on principle, the R25 Ultra is the spreadsheet pick by a wide margin.
Against the Fanatec Podium DD-25 at around $1,199, the R25 Ultra undercuts by roughly $300 (about ~£240 at FX) and brings the newer motor architecture. Fanatec wins on Xbox support via a licensed rim (Moza has no console licensing at all) and on the Fanatec rim catalogue. The R25 Ultra wins on PC value and on the modern hardware. Xbox racers go Fanatec; PC-only buyers go Moza.
The Asetek Forte tier is the closest industrial-spec rival on PC, but it lands at a meaningful premium. If you’re choosing between the R25 Ultra and the Asetek Forte, the spread on price is wider than the spread on feel for most drivers.
Verdict
If you race PC and you want the most torque-per-pound on the market without giving up the things that make a flagship feel like a flagship, the R25 Ultra is the right buy. The hardware holds its own against anything in the tier, the value against Simucube and Asetek is hard to argue with, and the Moza catalogue above and below the base has grown into something that competes on breadth.
If you race heavy LMP and formula content at full stiffness, this is the base. The headroom earns its keep in exactly those cars.
If you race on console, no Moza base carries any licence at all. Xbox drivers want Fanatec via a licensed rim; PS5 drivers have only the 8 Nm Fanatec GT DD Pro.
If you specifically need True Drive software depth, buy a Simucube 2 Pro instead. But if you want the most flagship you can get for the money and you race the cars that use it, this is the top of the Moza ladder, and a very good place to end up. Get it bolted down and go use all of it.
