The facts.
DescriptionThe whole story▼
The word Racing in the title of this listing describes the medium, not the motorcycle. It is a use label that Sprint Filter attaches to the F1-85 cloth wherever that cloth appears in the range, and it travels unchanged onto every airbox the cloth is cut for — a supersport machine, a naked, and here the CFMOTO MT-X 800. Nothing about ordering it converts the bike into something else, and nothing about the MT-X 800 is being reclassified by the label. It is worth saying plainly, because a title read at a glance suggests a promise that the part number SM292S F1-85 was never making.
Key Features
- Dry polyester woven from 22 µm threads, with a flow figure of 15,000 l/m²/sec
- Same fit, frame and airbox position as the standard element
- Oil-free throughout its life; regenerated with compressed air
- Roughly twice the working area of a typical performance filter
- Washable and reusable; no consumable to reorder
- Warranted two years from purchase, with no service interval of its own
Where the label comes from
By Sprint Filter's own account, its filters are the most widely used in MotoGP, Moto3, World Superbike, Supersport and Superstock — a manufacturer's statement rather than an independent measurement, and the origin of the word on this page. What the paddock buys the F1-85 for is one property: the highest flow figure in the catalogue, achieved with a different weave of polyester threads from 22 µm in diameter. The 85 in its name is not a micron rating, and in the maker's 100-micron test it retained 95.22 % against the standard element's 93.13 %, which is more than most people expect from a racing filter.
What that means for a road machine
Flow is only collected when something downstream is asking for all the air it can get. On a standard MT-X 800 ridden on public roads, those moments are brief and rare, and everything else in the intake and exhaust is still standard too. Meanwhile dust is a question for Sprint Filter's finer non-woven media rather than for either weave — a racing medium is chosen for a race weekend, not for a dusty road. So the honest recommendation for most owners is the standard element, and this one for riders with a specific reason: track days, or a machine already set up for sustained full-load running. In neither case does a drop-in element make a standard MT-X 800 noticeably faster.
Care and cleaning
Compressed air on the clean face, directed outwards, returns the element to service; the collected material leaves along the path it came in on. Lukewarm water and a little mild detergent take care of an oily film, rinsed through until the water runs clear. Dry it in moving air without hurrying it — no heat gun, no radiator, no flame — and refit it dry and untreated. The maintenance sheet is under the Downloads tab on this page.
Fitment & Compatibility
Cut for the airbox of the CFMOTO MT-X 800 as built from 2022 to 2026, one element per machine. In this medium the part number also serves a second CFMOTO model; the full list is in the Fitment tab.
