AIR FILTER SEAL KIT

One of the biggest issue we find leading to top end rebuilds and cylinder damage, is from the air filter not seating tightly on the airbox. This allows dirt and dust to be sucked into the cylinder damaging reeds and being dragged up the cylinder between the piston.

The plastic air filter cages fitted to the 2017-2025 KTM family of Mx and enduro and 2020 -2025 Beta Mx/enduro bikes only use two pins to secure the filter, which naturally warp from fuel, oil and heat changes, making gaps between the air filter and the airbox.

The solution.... SMX Air Filter Seal Kit.

Simply remove the air filter.

Clean the airbox seat base to remove and oil/grease (Ideally use acetone or neat petrol).

Although this idea is based around the above bikes cage fitment, it can still be used on the majority of off road/Mx bikes with an airboot base circumference (where filter sits) that is between 22 - 24 inch, then they will fit. Filters with centre bolt/screw type filter will be a tight fit but we have had positive feedback on this type of filter fitment.
