ATHENA Clutch Friction Plate Kit + cover gasket for KTM EXC, SX, XC, XCW 250, 300 and HUSQVARNA TE 250, 300 2013-2016

The ATHENA P40230021 clutch friction plate kit is designed for KTM EXC 250, EXC 300, SX 250, XC 250, XC 300, XCW 250, XCW 300 and HUSQVARNA TE 250, TE 300 from 2013 to 2016. 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: P40230021
• EAN code: 8052780272216
• Weight: 430 g
• Engine: 2-stroke

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.
