The small seals that stop oil running down the valves into the engine.

ATHENA offers these valve stem seals for KTM, HUSQVARNA, APRILIA and GAS GAS 1991-2025. Each valve slides in a guide. At the top of the guide, a small seal (the valve stem seal) lets through just enough oil to lubricate but stops it running into the combustion chamber.

Why replace the valve stem seals?

The benefits:

To be replaced every time the valves are removed.
Cure oil consumption and blue smoke on start-up.
An inexpensive part that protects valves and guides.

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 this part?

Blue smoke on start-up after standing overnight is the typical sign of hardened seals. They are also replaced at every head rebuild, even if they look fine.
