DescriptionThe whole story▼

Where the BEP01 covers one crankcase plug location on the 250EXC-F, Accossato also lists the SEP01 for the same 2012-to-2017 build, a second plug fitted to a separate spot on the same casing. Both close an opening in the engine case and replace whichever stock part was originally there.

Key Features

  • Crankcase plug for the KTM 250EXC-F, 2012 to 2017
  • Accossato code SEP01, fits a separate location on the engine casing
  • Available in orange or blue
  • Accossato also lists a second crankcase plug, BEP01, for this bike
  • Same part also listed for the Husqvarna FC 450, FE 501 and KTM 450EXC-F, among others
  • No German ABE on file; built for off-road and competition riding

Construction and Material Quality

Built to seat in its own spot on the 250EXC-F's casing, the SEP01 doesn't double up with the BEP01's location, so both plugs are needed if both are missing or damaged. Colour comes down to orange or blue with no effect on the seal either way. A plug sitting proud of the casing, rather than flush, has usually started to work loose and is worth tightening or replacing before it goes further.

A Second Plug on the Same Casing

Because this bike takes two separate crankcase plugs rather than one, it's easy to replace the more obvious BEP01 while forgetting the SEP01 sits a little further round the engine. Checking both at the same time, rather than assuming one implies the other, avoids coming back to the job twice. A used 250EXC-F that's changed hands more than once is a reasonable candidate for checking both plugs properly.

Fitment and Compatibility

The SEP01's own application list, per Accossato, covers the 250EXC-F across 2012 to 2017. This plug also fits the Husqvarna FC 450, the FE 501 and the KTM 450EXC-F, part of the wider engine family it belongs to, so an owner of more than one of these bikes can keep a single spare on hand. Confirming the exact build year against that list before ordering is still worth the extra minute.

Road Approval

No German ABE is on file for the SEP01, so Accossato lists it for off-road and competition use rather than for use on public roads.
