DescriptionThe whole story▼

Accossato also lists a second air filter for the Sherco SEF 300, part MSH1001, fitted to the 3.0 300 four-stroke built between 2012 and 2018. It sits alongside the AC5070 filter in Accossato's range for this bike, both built, as Accossato puts it, with off-road materials and technology for hard use away from the road. The foam element in the product photo carries the Accossato by Marchald print, the same finish used across this filter line.

Key Features

  • Accossato by Marchald air filter, part MSH1001, for the Sherco SEF 300 (3.0 300 4 STR.), built 2012 to 2018
  • Foam filter element with the Accossato by Marchald print, as shown in the product photo
  • Built with off-road materials and technology, in Accossato's own description, for sustained use away from the road
  • Listed alongside a second Accossato filter for this bike, part AC5070
  • Accossato lists the same filter for the Sherco SE 250, the SEF 250 and the SEF 450
  • No approval documentation on file; for off-road and competition use

Construction and Material Quality

What Accossato confirms for the MSH1001 is that it is built with off-road materials and technology for sustained hard use, doing its real work by stopping dust and grit from reaching the engine; no filter oil or cleaning kit is supplied with it. The foam element shown in the photo takes the Accossato by Marchald print and is sized to sit in the standard air box. Once the foam shows a split at the edge, or no longer sits flush against the housing lip, it has reached the point where it should be swapped rather than coaxed through another ride.

On the Workbench Between Rides

Checking the MSH1001 is one of the quicker jobs on a workbench routine, since the air box on this bike opens without much else coming off first. Many owners fold it into the same session as a chain check or an oil look-over, so the filter does not get forgotten between bigger services. A filter pulled out dry and dusty is doing its job; one that is damp, oily beyond the usual light coating, or visibly collapsed at one edge is worth a closer look before it goes back in. Keeping a simple tally of when the filter was last cleaned helps avoid the guesswork that leads to either an unnecessary swap or a filter left in far too long.

Fitment and Compatibility

Accossato places the MSH1001 against the Sherco 3.0 300 4 STR. for 2012 to 2018, matching the years given here, with the AC5070 covering the later SEF 300 range alongside it. The MSH1001 also appears on Accossato's list for the Sherco SE 250, the SEF 250 and the SEF 450, all part of the same filter family. Owners unsure which of the two Sherco filters suits their particular bike are better off checking the application list, or the part removed from the machine, before ordering.

Road Approval

Accossato has no approval documentation on record for the MSH1001, so it is listed for off-road and competition use rather than for road-registered motorcycles.
