The facts.

DescriptionThe whole story▼

Fitting this element is not a modification, and that is the practical point of the page. The frame, the seal and the sealing face are those of the series panel; the airbox stays as it left the factory and nothing is recalibrated. Which makes the medium a decision you can take back. Ride the trip on 7 microns, wash it, put the standard element back for the commute, and keep both — neither is used up by being taken out of the bike. Owners who treat the T12 as a second panel rather than a permanent fitting tend to get the most out of it.

Key Features

  • Dry polyester special nonwoven rated at 7 microns and 560 l/m²/sec
  • Interchangeable with the standard panel in the untouched 900 cc airbox
  • No oil at any stage, so nothing to reapply and nothing to migrate downstream
  • Roughly twice the filtering area of a conventional performance element
  • Serviced with compressed air and refitted, over and over
  • Two-year warranty; designed to last as long as the motorcycle

Keep the panel you took out

Label it with the date and the mileage, put it in a bag, and store it flat. Two things follow from that small habit. The first is that a medium chosen for one journey does not have to be lived with for the rest of the year, so the choice carries no penalty if the roads turn out to be tarmac after all. The second is that the bike can always be handed on in the configuration it was sold in, which matters more on a young model than on an old one. Both elements are washable, so neither shelf life nor a swap costs anything but the ten minutes the lid takes.

What the fine mat is answering

Dust, and specifically dust in concentrations the standard weave was not drawn for. The exchange is stated in the numbers and is not negotiable: 560 l/m²/sec here against 5,050 for the standard 80-micron panel, in return for a filtration limit of 7 microns instead of 80. More is held back, less gets through, and neither figure makes one cloth better than the other in the abstract. What has to be said alongside it is that no element of any weave makes a standard SRT 900 noticeably stronger. This one is bought for what it keeps out, not for what it lets in.

Care and cleaning

Compressed air, played across the clean face and worked outward, is the whole routine most of the time. When a film resists it, hand-warm water with a little mild detergent and a full rinse will deal with it. Everything then dries in moving air and nothing else: no radiator, no heat gun, no flame, because polyester tolerates dirt far better than it tolerates heat. The PM281T12 goes back in dry, and its maintenance sheet is available in the Downloads tab on this page.

Fitment & Compatibility

For the airbox of the QJ Motor SRT 900 S and SX, 900 cm³, built 2025 and 2026, one element per machine. The same housing appears on the 800 cc SRT and on a Benelli, three machines in total on this code; the list is in the Fitment tab.
