The MOZA KS is a 300mm butterfly style GT rim, which means it is the wheel you hold, not the base that drives it. You bolt it onto a MOZA wheelbase through the quick release, and it turns that base into a GT focused cockpit with a dense set of buttons, encoders, and paddles at your fingertips. It suits a PC racer who is building or growing a MOZA setup and wants a control rich, esports ready rim without stepping up to a full formula wheel.
This review looks at what the KS adds to a base, how its controls and build hold up, and who should choose a different rim. We compared the manufacturer listing with recurring owner feedback, and you can read how we review. If wheel rims and quick releases are new to you, start with Getting Started.

Why a rim is a separate decision from the base
Before judging the KS, it helps to know what a rim does and does not do. The force you feel comes from the wheelbase motor, not the rim, so the KS does not change how strong or detailed your feedback is. What it changes is everything you touch: the diameter and shape of the wheel, the feel of the grips, the placement and quality of the buttons, and the paddles you shift with. A good rim makes a base easier to drive and more comfortable over long sessions, and it puts the controls you use most within reach so you are not fumbling mid corner. That is the lens for the KS. It is an ergonomics and controls upgrade, matched to a base you already own or plan to buy.
Controls and how it feels to use
The KS is built around a rich control layout for a GT rim. It carries 10 short travel programmable RGB buttons, 20 position thumb encoders, 12 position rotary encoders, and depressible joysticks, all configurable through the MOZA Pit House software along with the RPM indicator behavior and LED colors. Owners consistently describe the layout as well organized and the buttons as positive and easy to find without looking. The shift paddles use a 0.3mm non-contact hall sensor design in anodized aluminum, and reviewers who race with them report clean, consistent shifts and a solid feel. For drivers who lean on encoders and switches mid race, in endurance and GT titles especially, this is a lot of usable control on one rim.
Build and comfort
The case is a carbon fiber reinforced composite, which keeps the KS light while owners report it feels sturdy rather than hollow. The grips use a corrosion resistant coated TPE rubber that reviewers find high friction and comfortable over long stints, and the 300mm butterfly shape gives the open, hands forward posture GT drivers tend to prefer. The package includes transparent button stickers and a dust bag. The paddles being anodized aluminum rather than plastic is the kind of detail that separates this rim from cheaper options, and it shows in the reported longevity.
Compatibility and setup
The KS connects through the MOZA Quick Release and works with all MOZA bases, so if you already run a MOZA wheelbase it is a direct fit. It can also attach to a range of third party bases through an adapter, but the MOZA Universal Hub Kit PC adapter is not included and has to be bought separately, which is worth budgeting for if you are not on a MOZA base. This is a PC rim. If you are choosing a base to pair it with, our reviews of the MOZA R9 and the MOZA R12 cover two common partners.
Who should buy it, and who should skip it
| Buy the KS if | Skip it if |
|---|---|
| You run a MOZA base and want a control rich GT rim | You do not own a compatible base and want a complete wheel |
| You want lots of encoders and switches for GT and endurance racing | You want a formula style rim with a flat top and bottom |
| You value aluminum hall paddles and a carbon reinforced build | You need mechanical shift paddles with a clicky throw over hall paddles |
How it scores
The WSR Score reflects verified buyer ratings gathered and normalized on a consistent scale, not an editorial rubric. You can read what goes into it on How We Review. On that basis the KS rates strongly, which fits its standing as a well finished GT rim that owners keep on their MOZA bases.
Frequently Asked Questions
What is the difference between the MOZA KS and the KS Pro?
The KS Pro is the more feature packed sibling of the same 300mm butterfly style rim. This review covers the KS. According to MOZA’s product page and trade coverage, the KS Pro adds a built in display, more rotary and thumb encoders, and rear buttons. Choose the KS if you want the core GT layout without the extras, and check MOZA’s listing for the full KS Pro spec sheet.
Alternatives worth a look
If you want more of a shift and clutch focus, our MOZA GS V2P review covers a carbon rim with a dual clutch system and mechanical keys, the natural sibling to weigh against the KS. To choose the base underneath either rim, our best direct drive wheels under $1000 guide ranks the strongest options.
