Simsonn Pro X Ultra With a Moza R9: Right First Pedals?

The Simsonn Pro X Ultra is a reasonable first pedal set for a Moza R9, provided it fits the budget at the price you actually find. It is a load-cell set, it does not depend on the Moza base for its signal, and it adds haptics that the Moza SR-P does not offer. If you want the least-fuss, same-brand option, the standard Moza SR-P is the rival to weigh. Skip the SR-P Lite whichever way you go.

This page rests on manufacturer documentation and published reviews. Nothing here was tested first-hand, and no independent lab has published measurements of the Ultra, so the Simsonn figures below are the maker’s own.

What the Pro X Ultra gives you

Simsonn’s listing for the Pro X line gives a 200 kg load cell on the brake and 20 kg load cells on clutch and throttle, with a 16-bit ADC and a 32-bit dual-core processor. A retailer roundup describes the Ultra as load-cell on all three pedals, with an adjustable hydraulic-style brake rod, an RGB pressure display and per-pedal curve control. Haptic motors are the Ultra’s distinguishing feature, and Simsonn’s Manager software recently gained live telemetry graphs and fixes to the RGB and haptic modes.

Owner feedback on Simsonn’s own store is mostly positive on adjustability and build, with a few complaints: some clutch LEDs failing within a week on one buyer’s set, and haptic motors shipping later than the pedals. Treat these as individual reports, not failure rates.

Does it work with a Moza R9?

Moza’s SR-P pedals plug into the Moza base or hub, and they are configured in Pit House. Simsonn pedals are a separate USB device with their own software, so they should be recognised by the PC independently of the base. Check the current Simsonn listing for the exact connection and any adapter before you order. The practical consequences:

• The R9 itself places no pedal restriction on a USB device. You calibrate in Simsonn Manager, not Pit House.
• You use a PC USB port or hub port for the pedals rather than the base’s pedal port.
• If you ever swap base brands, the pedals come with you. Moza SR-P pedals are the better fit only if you stay in the Moza ecosystem.

Where the Moza SR-P wins

Reviewers praise the standard SR-P as a natural match for the R9: Traxion’s review covers its load-cell brake and range extenders, and RacingGames pairs it with the R9 in its base review. It has one cable path to the base and one software package. Moza’s accessory ecosystem also matters: its support page states that SR-P and SR-P Lite parts are not interchangeable, so any upgrade kit you buy must match the exact set.

Choose the SR-P if you want the simplest setup and no haptics. Choose the Simsonn Ultra if you want haptics and a larger tuning range, and are comfortable with a smaller-brand support route (the usual warranty path is the maker’s own shop, so confirm return terms for your country).

Why to skip the SR-P Lite

Skip the Lite. Its brake is a Hall sensor, as opposed to the load cell in the standard SR-P, and Moza’s compatibility documentation ties it to the R5 bundle, with Lite-only brake and clutch add-ons that do not fit the standard SR-P. Reviews of the R9 discuss the standard SR-P, and nothing found confirms the Lite as a supported R9 partner. A pressure-based brake is the main reason to upgrade from a bundle pedal, and the Lite does not deliver it.

What to decide first

1. Is the Ultra under your ceiling at the price you can really get it? If the cost drifts above it, drop to the SR-P rather than a Hall-sensor set.
2. Do you want haptics and RGB? If not, the extra spend buys little.
3. Will you stay with Moza? If yes, the SR-P’s integration counts; if you may change bases, the Simsonn’s independence counts.

What is still unresolved: no lab has compared the Ultra’s linearity or long-term wear against the SR-P, so brake feel claims on either side are owner opinion.
