During Gamescom 2025 Moza Racing put itself firmly in the spotlight with the introduction of two new wheelbases: the Moza R21 Ultra DD Wheel Base and the Moza R25 Ultra True Torque DD Wheel Base. Combining brute force with sophisticated technology, these wheelbases are positioning themselves remarkably sharply in the market. In this comprehensive article, we take you through all the innovations, specifications, extra features and the impact these models can have for avid sim racers and professional drivers alike.
Development and follow-up: moving up the ladder
The Moza R21 Ultra DD and R25 Ultra True Torque DD have been completely redesigned, replacing the original R21, which will join the R16 was launched. After a V2 update in 2023, this is the first true successor. Where the first R21 already impressed with reliability and performance, these new models raise the level considerably.
With improved force feedback technology, an innovative motor design and a completely new look, Moza Racing aims to win over not only existing users, but also sim racers who until now mainly looked at brands like Simucube or Asetek. This evolution shows that Moza its product line maturing and targeting the absolute top end of the market.
Next-gen flat-wire motor: true zero cogging and compact power
At the heart of both wheelbases is the completely new flat-wire motor. It is designed to true zero cogging deliver. Whereas traditional engines sometimes allowed small hiccups or 'steps' in force feedback to be felt, this technology promises a seamless and smooth driving experience.
- R21 Ultra DD: 21Nm peak torque - ideal for avid racers looking for powerful feedback but not necessarily needing the maximum.
- R25 Ultra True Torque DD: 25Nm peak torque - for those for whom absolute power and realism are key.
In addition, the R25 offers 26% higher torque density than comparable models in this segment. This means more power packed into a more compact body, improving both performance and efficiency. In practice, this translates to a steering feel even closer to real motorsport.
Faster than the rest: industry-leading torque response
According to Moza, these wheelbases offer the fastest torque response in the entire industry: ≥10Nm per millisecond. This figure exceeds that of well-known competitors, such as the Simucube 2 Pro (8.0 Nm/ms) and the Asetek Invicta (9.4 Nm/ms). In practice, this means that every change on the track - from losing grip to a small bump - is felt faster and more accurately in the wheel. For sim racers looking for maximum precision and consistency, this can make THE difference in competitive races and championships where milliseconds are decisive.
Real-time torque sensing: accuracy in detail
The R25 Ultra is equipped with a advanced torque sensor with a sampling accuracy of 0.1% and a response rate of up to 2 kHz. This translates every steering movement into the simulator with unprecedented precision. Together with the 21-bit magnetic encoder, which offers more than 2 million points of precision, creates an unprecedented realistic steering feel. This is especially important during endurance racing or eSports events, where long-lasting consistency and detail are key to success.
Renewed design: CNC aluminium and RGB telemetry
Besides performance, the design has also been completely revamped. Both models are housed in a CNC-machined aluminium housing, which not only provides a robust and luxurious look, but also promotes cooling and durability.
One notable addition is the customisable RGB lighting. These lights can be linked to telemetry and change colour, for example, at switch moments, ABS activation or flag signals. This not only makes it a visual spectacle, but also provides extra feedback you can use during races. The R25 even includes dual RGB light strips along the top for 16.7 million colour combinations and fully adjustable effects. This gives you the ability to completely tailor the look of your simulator to your personal preference or team colours.
Additional features of the Moza R25: versatility and safety
- Versatile Mounting Options: Supports bottom, front and side mounting, making it easy to attach to a variety of rigs.
- Extreme Durability: Thanks to slip ring technology, tested for more than 10 million rotations, the connection remains stable and lag-free at a transfer rate of 2M/s.
- Native Ecosystem Integration: Features connectors for all important Moza peripherals such as pedals, shifters, dashboards and handbrakes - without additional USB hubs or cables.
- Hands-off protection: Automatically detects when you take your hands off the wheel and prevents dangerous oscillations by safely centring the wheel.
- Cloud-based App Configuration: Through the Moza app, you can easily adjust settings, save profiles and fine-tune your set-up from one central environment.
Force feedback algorithm and software: smart power
The new engines are controlled by the New Force Feedback Algorithm, which guarantees balanced and realistic power transmission. Combined with the powerful 600MHz CPU this system can process data extremely quickly, ensuring smooth and consistent feedback. This makes it easy to fully tune the base to your driving style and preferences. For novice sim racers, this is an accessible entry point to high-end hardware, while experienced drivers will benefit from its refined fine-tuning capabilities.
Price and availability: high-end performance at a competitive price
One of the biggest surprises of this release is the pricing. Where wheelbases with similar performance often cost above a thousand euros, Moza opts for aggressive positioning:
- R21 Ultra DD Wheel Base: €799
- R25 Ultra True Torque DD Wheel Base: €999
This puts considerable pressure on the competition and makes high-end technology more accessible to a wider group of sim racers. For many drivers hesitating about a switch to direct drive, this is a threshold lowering option.

Comparison with competitors: a serious challenger
Where Fanatec, Simucube and Asetek have been setting the standard in the high-end segment for years, Moza brings with the R21 and R25 an alternative that is attractive in terms of both performance and price. The difference in torque response may be of particular interest to eSport drivers who need to make decisions in milliseconds.
Moreover, the competitive price makes the move to a top-class wheelbase accessible to a wider audience. For users already in the Moza ecosystem sit, integration with existing pedals, shifters and accessories is a big advantage. This not only lowers entry costs, but also keeps the set-up clear and reliable.
Personal impression: a new standard in the making?
The introduction of the R21 and R25 feels like a strategic move by Moza to claim a bigger role in the high-end segment. The combination of brute force, technological innovation and competitive price makes these wheelbases particularly interesting. Where the established brands have already earned their reputation, Moza is showing that it dares to compete - and may even set a new standard.
For sim racers ready for the next step in realism, now seems like the time to seriously consider Moza. First impressions are that Moza has struck a balance between performance, durability and accessibility. This could very well be the product with which the brand finally breaks through to the absolute top!
