What it is not is something a rider can detect from the saddle of a standard motorcycle. Intake restriction on a series machine sits behind a throttle body, an exhaust and a fuel map that were all specified around the paper panel, and a change upstream of that chain shows up on instruments long before it shows up in an impression. The CM195S F1-85 is a racing element, and racing is where such a difference is measured rather than felt.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRacing polyester medium, dry, woven from threads from 22 µm\u003c\/li\u003e\n\u003cli\u003e15,000 l\/m²\/sec of rated flow — the highest figure in the Sprint Filter media range\u003c\/li\u003e\n\u003cli\u003eRetention measured at 95.22 % of 100-micron particles in the manufacturer's comparison\u003c\/li\u003e\n\u003cli\u003eRoughly double the filtering surface of other performance elements, inside the standard box\u003c\/li\u003e\n\u003cli\u003eNo oil, no remap, no airbox modification: it replaces the factory panel as it is\u003c\/li\u003e\n\u003cli\u003eWashable, reusable, two years of warranty from the date of purchase\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eMeasured, not felt\u003c\/h2\u003e\u003cp\u003eBy Sprint Filter's own account, this is the most widely used air filter in MotoGP, Moto3, World Superbike, Supersport and Superstock — a manufacturer's statement about use rather than an independent measurement, and worth reading as one. What a team draws from a washable element is repeatability: the same known intake condition at the start of every session, restored with an air line instead of a parts order. On a road-registered Trials none of that apparatus exists, and the honest position is that the extra capacity goes unused.\u003c\/p\u003e\u003ch2\u003eWhat it costs to find out\u003c\/h2\u003e\u003cp\u003eThis element runs to about three and a third times the standard P08 for the same airbox, and roughly three times the fine P14. That is not a small experiment, and it is not one to encourage on a standard machine: a drop-in filter does not make a series motorcycle noticeably stronger, and buying more flow than the engine draws changes nothing except what you paid. The standard weave is the sensible rung here; this one earns its place on a bike used on track.\u003c\/p\u003e\u003ch2\u003eCare and cleaning\u003c\/h2\u003e\u003cp\u003eCompressed air from the clean side, moving steadily across the face of the CM195S F1-85, is the whole routine for dry dirt. Anything greasy comes off with lukewarm water and a mild detergent, thoroughly rinsed afterwards. The element then dries in open air, never with heat and never over a flame, and returns to the box with nothing applied to it.
