ATHENA Clutch Friction Plate Kit + cover gasket for HUSQVARNA FE 250, 350, KTM EXCF 250, 350 and GAS GAS ECF 250, 350 2017-2023

The ATHENA P40230025 clutch friction plate kit is designed for KTM EXCF 250, EXCF 350, HUSQVARNA FE 250, FE 350 and GAS GAS ECF 250, ECF 350 from 2017 to 2023. The friction plates transmit engine torque to the gearbox by gripping against the steel plates. As they wear, they get thinner: the clutch slips, overheats and the bike loses traction.

Specifications

• Brand: ATHENA
• Manufacturer part number: P40230025
• EAN code: 8052780272254
• Weight: 430 g

When to replace it?

• Revs rise but the bike doesn't pick up speed (slipping), especially in the higher gears.
• Engagement point that wanders, clutch that judders or smells burnt.
• Plates below the minimum thickness given in the manual.

Measure plate thickness with a vernier caliper at every clutch check and replace the plates once they're below the minimum in the manual, or as soon as they slip.

Fitting tips

1. Soak the new friction plates in gearbox oil before fitting them.
2. Check the steel plates (flatness, blueing) and the clutch springs; replace them if necessary.
3. Make sure the basket fingers aren't notched: if they are, the clutch will snag.
4. Reassemble in the original order, tighten to the manufacturer's torque and close up with a new clutch cover gasket.
