The facts.
DescriptionThe whole story▼
Off-road and extreme is a description of air, not a description of motorcycles. A rider whose SRT 700 never leaves a sealed surface can still meet the conditions this mat was drawn for — a summer of farm traffic, a season of roadworks, a fortnight of unsealed mountain passes — while an adventure-styled machine used between cities may never meet them at all. The label belongs to what the filter will breathe. So the decision sits with your roads and your calendar, and not with the way the bike is styled or with what its brochure photographs promise.
Key Features
- Polyester special nonwoven, dry, filtration down to 7 microns
- Rated flow of 560 l/m²/sec, a ninth of the standard weave for the same airbox
- No oil at any point: regenerated with compressed air and put straight back
- Series frame and sealing face, so nothing is modified and nothing remapped
- Roughly double the filtering surface of a conventional performance element
- Two-year warranty; designed to last as long as the motorcycle
Reading conditions instead of categories
The evidence is on the bike after a ride. A fine grey film on tank and screen at the end of a dry week, a rim of dust in the bodywork recesses, visibility dropping behind the vehicle ahead on an unsealed road: that is the air the intake is drinking, and it beats any category printed on a spec sheet. Riders whose evidence looks like that are the ones this mat was made for. Riders whose bikes come home clean have their answer too, and it is the standard weave.
The exchange, stated once
560 l/m²/sec here against 5,050 for the 80-micron road cloth, in return for a filtration limit of 7 microns instead of 80. More is stopped, less is passed, and the two move together on one lever, so neither medium outranks the other and both are right somewhere. What holds for both needs saying as well: neither makes a standard SRT 700 noticeably stronger. Airbox, throttle bodies and calibration set what the engine does, and a change of cloth in the middle of that chain does not revise them.
Care and cleaning
Begin with air on the clean face, moved slowly so the mat releases what it holds instead of taking it deeper. Should a film survive that, hand-warm water with a small amount of mild detergent and a patient rinse will clear it. Drying is done in moving air alone, since heat destroys the material where dust merely loads it, so nothing warm goes near it at any stage. The SM258T12 is refitted dry and untreated, and the maintenance sheet for it sits under the Downloads tab on this page.
Fitment & Compatibility
Made for the airbox of the QJ Motor SRT 700 and SRT 700 X, built 2024 to 2026, one element per machine. Two motorcycles share this code, the other a Benelli; the complete list is in the Fitment tab.
