DescriptionThe whole story▼
Accossato's second filter for the EN 450 4T carries part number MTM704, matched against the EN 450 FI built from 2015 to 2018 alongside the AC5070. Accossato describes the filter as built with off-road materials and technology for sustained hard use away from tarmac, and the foam element pictured carries the Accossato by Marchald print that marks the whole filter line.
Key Features
- Accossato by Marchald air filter, part MTM704, for the TM Racing EN 450 4T (EN 450 FI), built 2015 to 2018
- Foam filter element bearing the Accossato by Marchald print, as shown in the product photo
- Accossato's own description: built with off-road materials and technology for sustained hard use
- A second Accossato filter, part AC5070, is also listed for this bike
- Accossato lists the same filter for the TM Racing EN 250 4T, the MX 250 4T and the MX 450 4T
- No approval documentation on file; for off-road and competition use
Construction and Material Quality
For the MTM704, Accossato confirms the fitment, the build years and the off-road materials and technology line; what the foam is there to do is stop grit reaching the engine on the intake side, with no oil included. The foam element carries the Accossato by Marchald print and is shaped for the EN 450 4T's standard air box. Once the foam has gone brittle at the rim or picked up a tear from being forced into place, it is no longer reliable and should be replaced.
Keeping Two Filter Codes Straight
With both the MTM704 and the AC5070 listed for the same bike, a workshop handling more than one EN 450 4T can end up with filters mixed between machines if nothing is labelled as it comes off. Writing the part number on a piece of tape stuck to the filter, or simply keeping cleaned filters in separate bags per bike, avoids that kind of mix-up. Labelling each filter by code also means knowing which spare is which when restocking. Checking the part removed from the bike against Accossato's own listing settles any doubt before an order goes in.
Fitment and Compatibility
Accossato lists the MTM704 against the EN 450 FI for 2015 to 2018, matching the years given here, with the AC5070 as the other filter listed for this bike. The MTM704 also covers the TM Racing EN 250 4T, the MX 250 4T and the MX 450 4T on Accossato's list. Comparing the part number on the filter taken off the bike against the application list confirms which of the two is actually fitted.
Road Approval
Accossato has no approval documentation on record for the MTM704, so it is listed for off-road and competition use rather than for road-registered motorcycles.
Scope of Delivery
