ATHENA Cylinder Head Gasket O-ring Ø64.00 x 2 mm for KTM, APRILIA, YAMAHA and HUSQVARNA 1986-2025

ATHENA offers this cylinder head gasket for KTM, APRILIA, YAMAHA and HUSQVARNA 1986-2025. The head gasket takes the pressure and heat of every combustion. It is crushed when the head is torqued down and must be replaced every time the head comes off.

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 head gasket on your KTM SX 150?

Loss of compression, a dropping coolant level, bubbles in the radiator or traces between cylinder and head: the gasket needs changing. It is also replaced every time the head comes off.

No manufacturer figure in hours for this model. Cross-Mania guideline: compression check every 20 h of hard use and every 40 h of leisure riding.
