ATHENA connecting rod kit for KTM SX 85, HUSQVARNA TC 85 and GAS GAS MC 85 from 2013 to 2026

ATHENA offers this connecting rod kit for KTM SX 85, HUSQVARNA TC 85 and GAS GAS MC 85 from 2013 to 2026. The rod passes the piston’s motion to the crankshaft. Its big-end bearing spins at very high revs and eventually develops play.

Why replace the connecting rod?

The benefits:

• Remove the play that causes noise and vibration.
• Make a high-hours engine reliable again.
• Cheaper than a complete crankshaft when the flywheels are good.

Why choose ATHENA?

Athena, the Italian manufacturer founded in 1973, is an original-equipment supplier to manufacturers such as KTM and Ducati: the same standards for your replacement parts.

When should you replace the connecting rod?

Unusual vibration, a deep knock that follows engine speed or play in the con-rod: the bottom end needs a rebuild.

Recommended hours for a bottom-end rebuild (manufacturer recommendation for the KTM SX 85, Husqvarna TC 85 2018-2023):

• Racing: every 40 h.
• Leisure: no KTM figure; have the wear checked at every top-end rebuild.
• KTM SX 85, Husqvarna TC 85, GASGAS MC 85 since 2024: racing: every 90 h.
