DescriptionThe whole story▼

The WR450F is the larger-displacement sibling of the WR250F in Yamaha's enduro line, and its crankcase carries the same kind of plug as any other off-road four-stroke, sealing an opening that only gets attention during a service. Accossato lists a blue crankcase plug for the WR450F built between 2010 and 2017, a direct replacement for the factory part.

Key Features

  • Crankcase plug for the Yamaha WR450F, 2010 to 2017
  • Accossato code KEP11, fitted to the engine crankcase
  • Replaces a lost, damaged or corroded original plug
  • Available in blue
  • Same part also listed for the Yamaha YZ250F
  • Accossato also lists a rear brake reservoir cover for this bike
  • No German ABE on file; built for off-road and competition riding

Construction and Material Quality

Accossato makes this plug to seal the WR450F's own crankcase opening, so it threads in the way the factory plug does. Blue is the only finish offered for this part, giving a small highlight at engine level. A plug that has corroded in place or gone missing during a previous service is simple to put right without any wider engine work.

A Small Part Worth Checking During Winter Storage

Riders who lay the WR450F up over winter often use the downtime to go over the engine more closely than a quick seasonal service would normally call for, and a crankcase plug left loose or corroding quietly is exactly the kind of thing that only gets noticed during that longer look. Fitting a fresh plug before the bike goes back into regular use is a cheap way to rule out one more potential source of a leak before the riding season starts again.

Fitment and Compatibility

Accossato names the WR450F built between 2010 and 2017 on this plug's own application list. The identical plug also fits the Yamaha YZ250F, sharing the same crankcase opening. Accossato also lists a rear brake reservoir cover, PBH01, for the WR450F, worth ordering alongside this plug if other parts are due for a refresh.

Road Approval

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