What Nobody Publishes

Who has to answer what

An owner who cannot find a figure rarely concludes that the figure is unpublished. They conclude that the answer is favourable, or they take the first number a forum offers. Both are worse than knowing the number does not exist, which is what this page is for.

There are three manufacturers in view. Camso, whose systems are sold through dealers. Kimpex, the same. Mattracks, which sells direct and is covered on its own page. Each entry below names which of them would have to answer, because “nobody publishes it” is a different claim from “this one manufacturer does not.”

What has to be modified to fit a Commander WS4

Who would have to answer it. Kimpex.

What it publishes instead. Nothing per application, and this is the largest single gap on the page. Of the 733 Commander WS4 rows in the catalogue, 0 carry a published condition. The field is empty on every one of them. The product page publishes a flotation surface, lug heights, a frame description, a speed loss and an installation time, and no statement about interference, clearance, removal or modification on any specific machine.

Kimpex publishes no per-application condition data at all: every Commander WS4 record in this catalogue has an empty remarks field. The absence of a WS4 entry below means nobody has published a condition for it — not that none exists. Camso is the only manufacturer here that publishes these flags, so this page is necessarily a Camso view of the catalogue.

The consequence is precise and it is the reason this entry leads. An owner searching for what the install will require on their machine finds no entry — and reads that absence as “no modification required.” It is not. It is an absence of published data.

What to do with it. Put the question to the installing dealer and get the answer on the order: what comes off, what stays off, and whether anything is cut or drilled. A shop that has fitted the combination knows; the product page will not tell you either way.

What Camso’s remark G physically interferes with

Who would have to answer it. Camso.

What it publishes instead. A letter and a definition. Camso is the only manufacturer here that flags conditions per application at all, which makes its guide by far the more useful document — and the legend is the whole of it:

A* Certain rectriction apply · B* Suspension lift kit required · C* Temporary body parts removal · E* Important speed reduction · F* No compliance with accessories · G* Permanent interference · H* Vehicle with cargo box · J* CVT/AIR intake vent kit recommanded · K* Temporary vehicule modificationCamso ATV/UTV application guide, August 2026, read 2026-09-26. Spellings are the guide’s own.

Above that legend sits one standing sentence, and it is the closest thing to per-machine detail anywhere in the document:

Minor modification and light interference are possible on any modelCamso ATV/UTV application guide, August 2026, read 2026-09-26

So 117 of the 1389 rows in the catalogue carry a flag, all of them from the 656 Camso rows, and not one of them says what the interference is, where it is, which component it involves, or whether the machine goes back to standard afterwards. Nothing published says it is minor, and nothing published says it is not.

One smaller absence inside the same document. Remark D appears on rows throughout the guide dated August 2026 — the Arctic Cat manual-shift rows among them — and the legend printed at the head of the same page does not define it. Camso publishes no revision history for these codes, so what D means is not recoverable from anything Camso publishes. If it is on your row, ask the dealer to look it up in the revision the shop is working from.

What to do with it. The questions that get a flagged row answered at the counter are listed on what permanent interference looks like on paper.

Which flag a catalogue condition corresponds to

Who would have to answer it. Camso, and anyone who restates its codes as words.

What it publishes instead. Letters on one side, sentences on the other, and no published mapping between them. The catalogue carries 6 distinct condition strings. Matching them against the legend quoted above leaves 1 with no counterpart in the August 2026 revision — “Permanent vehicle modification”, and 4 legend codes with no counterpart in the catalogue: A, E, F, J.

Whether the unmatched string is a code from an earlier revision, a different wording of a current one, or a transcription error is not recoverable: Camso publishes no code history and no concordance. So if your row carries a condition in words rather than a letter, ask which letter it came from and which revision of the guide the shop is reading.

How much more fuel a tracked quad uses

Who would have to answer it. All three. None does.

What they publish instead. Speed loss. Camso states an average loss of about 30%, up to 50%on some vehicles, and phrases the same thing on the T4S page as keeping two-thirds of the vehicle’s original speed. Kimpex publishes 35% for the Commander WS4. Not one of the pages read on 2026-09-26 carried a fuel consumption figure, a range figure, or a percentage of any kind attached to fuel.

A figure of roughly 20–30% more fuel is in circulation, including in retail copy, with no manufacturer source behind it. If somebody quotes you a fuel figure for tracks, ask where it came from. Plan range off your own tank instead: the published speed loss is the closest thing to a guide, and it is a speed figure rather than a consumption figure.

What a Mattracks EZ ATV costs in speed

Who would have to answer it. Mattracks.

What it publishes instead. A recommended maximum gross vehicle weight and a ground contact surface area. Neither the EZ Series product page nor the EZ Series specification sheet carried a speed loss, a maximum speed, a maintained-speed fraction or a speedometer correction when both were read on 2026-09-26.

That is a single-manufacturer hole rather than a category-wide one: the figure exists for the other two systems and is directly comparable between them. Mattracks publishes rows the others do not — a break of the ground contact figure into hard and soft surface, an operating temperature range, a road wheel count — and omits the one row a buyer choosing between platforms would reach for first. So a speed comparison against a Camso or Kimpex system cannot be made from published figures, in either direction.

How long a Commander WS4 is covered

Who would have to answer it. Kimpex.

What it publishes instead. Three different states of the same fact, depending on where you look. All three were checked on 2026-09-26 and all three are printed here, because reconciling them by picking one would be inventing a warranty term.

• The Commander WS4 product page published no warranty term at all. It carries a link to the warranty page and no figure of its own.
• The Kimpex US warranty page published, for Commander track kits, a basic 1 year plus an additional 1 year on registering the product.
• A 3 year figure for Commander track systems is in circulation, including in third-party retail listings. No Kimpex-published page stating it could be reached on 2026-09-26.

Confirm the term in writing with Kimpex before relying on any of the three, and note the registration step: on the published version, half the coverage depends on registering the product, which is a thing to do on the day rather than later.

Camso’s equivalent is unambiguous, and carries a condition that costs more than the length:

We offer a 2-year limited warranty of our ATV and UTV track systems, which covers manufacturing defects related to materials and workmanship. This warranty applies exclusively to parts and components of the track system and is valid when the track systems are installed by an authorized Camso dealer or distributor.powersports.camso.co warranty page, read 2026-09-26

Mattracks published no warranty term on either of the EZ Series pages read the same day.

How long a system lasts, and what fails first

Who would have to answer it. All three.

What they publish instead. Procedures and periods, never outcomes. Camso publishes a break-in schedule with inspection intervals and maximum real speeds for the first few hours, and a limited warranty of twenty-four months conditioned on dealer installation. Kimpex publishes an initial installation time of 1.5 hours and a subsequent swap time of 30 minutes. None of the three publishes a service life, an hours-to-replacement figure, a wear limit, a failure rate, or which component goes first.

With no published wear limit, the hour meter is the only comparable figure there is — so on a used set, ask for the machine’s hours and how many of them were on tracks, and inspect rather than infer. What to look at is on inspecting a used system.

Whether one system’s footprint is larger than another’s

Who would have to answer it. All three, and none of them measures the same thing.

What they publish instead. Three names for one quantity, and no method for any of them. Camso publishes ground coverage in square inches — and calls the same row ground surface on its own R4S sheet. Kimpex publishes flotation surface in square metres and square inches. Mattracks publishes ground contact surface area, stated twice, once for hard ground and once for soft, with a footnote that every figure on the sheet is per corner.

Nobody publishes whether the figure is a static contact patch or a projected area, under what load, at what track tension, or on what surface. Mattracks is alone in saying which of front-versus-total it means.

So a cross-brand footprint ranking cannot be built from published figures, and any table that shows one has done arithmetic across three different definitions. If flotation is the question, compare the dimensions every manufacturer publishes the same way: track width, track length and lug height, unit by unit.

What a set weighs once it is on the machine

Who would have to answer it. All three.

What they publish instead. Per-unit figures on three different bases. Camso publishes front and rear unit weights for the T4S plus an approximate mount-kit weight. Kimpex publishes front and rear unit weights for the WS4 and states explicitly that they are without the mount kit. Mattracks publishes one assembly weight for the EZ ATV under a footnote that all specifications are per corner.

None of the three publishes the installed total — the figure that actually matters when the question is a storage rack, a trailer tongue, or whether one person can carry a corner. Adding a published unit weight to a published mount-kit weight produces a number no manufacturer stands behind, and the hardware that differs between machines is the part nobody itemises. A certified scale with the trailer loaded is the only answer available; trailering a tracked quad covers what to weigh and what to measure.

Whether power steering changes steering effort on tracks

Who would have to answer it. Camso, Kimpex, and the vehicle manufacturers.

What they publish instead. Nothing. No published statement about steering effort with tracks fitted, with or without power assist, was found on any manufacturer page read on 2026-09-26. Camso publishes a caution against sportive driving and repeated fast turns, and a minimum-speed instruction for sharp turns during break-in, which is about component life rather than effort at the bars.

The claim that electronic power steering makes steering on tracks noticeably easier is widely repeated and nowhere published. If it is going to decide your purchase, ride a tracked machine before you buy rather than reading about it.

What to do with a gap

Every entry above has the same practical shape, and it is worth stating once rather than nine times. A figure nobody publishes is a figure to get in writing from somebody who is accountable for it, before money changes hands:

• Modification, interference and what comes off — from the installing dealer, written on the order.
• Warranty term and what conditions it — from the manufacturer, in writing, including whether registration is required.
• Weight, width and height — from a scale and a tape on your own machine.
• Wear and service life — from an hour meter and an inspection, not from an estimate.
• Fuel, range and steering effort — from riding the machine, because no document answers any of the three.

A number quoted without a source is the thing to be most careful about on this subject. Most of the figures people repeat about tracked quads are in that category, and the ones above are the ones worth checking.
