WISECO Clutch Friction Plate Kit for KTM EXC 450, EXC 520, EXC 525, SX 520, SX 525, XC 450, XC 525 2000-2012

The WISECO WWPPF072 clutch friction plate kit is designed for KTM EXC 450, EXC 520, EXC 525, SX 520, SX 525, XC 450, XC 525 from 2000 to 2012. 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.

Key features

• Complete set of friction plates to original dimensions.

Specifications

• Brand: WISECO
• Manufacturer part number: WWPPF072
• Weight: 320 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.
