ATHENA Spark Plug Hole Seal for YAMAHA WRF, YZF 250, 450 and FANTIC XEF, XXF 250, 310, 450 2014-2026

ATHENA offers this spark plug hole seal for YAMAHA WRF, YZF 250, 450 and FANTIC XEF, XXF 250, 310, 450 2014-2026. On a 4-stroke the plug passes through the valve cover: this seal stops oil filling the well and reaching the plug cap.

Why replace this gasket every time it is removed?

The benefits:

• A new gasket guarantees a perfectly sealed joint.
• Material designed to withstand heat, oil and coolant.
• An inexpensive part that saves doing the job twice.

Why choose ATHENA?

Athena, founded in 1973 by Giovanni Mancassola near Vicenza and based in Alonte (Italy), designs gaskets, pistons and cylinder kits; it supplies original equipment to manufacturers such as KTM, Ducati, Fantic and Triumph.

When should you replace the gasket on your YAMAHA YZF 250?

Seepage around the cover or a leak after reassembly means it must be replaced: a crushed gasket never seals properly again.
