Product Details

The Wiseco CSK041 Clutch Spring Kit is a direct-replacement upgrade designed for KTM 250, 450, 520, and 525 models. Engineered for riders who demand reliable clutch engagement under hard use, these springs deliver a firmer, more consistent feel compared to stock components.

Key Features:

  • Premium steel construction — manufactured from high-grade steel for superior durability and fatigue resistance
  • Shot-peened finish — surface treatment that increases spring strength and extends service life
  • Heat-treated — thermal processing ensures consistent spring rate retention over time
  • Stiffer spring rate — provides a more positive clutch lockup, reducing clutch slip under heavy throttle and aggressive riding conditions
  • Direct replacement — designed as a drop-in upgrade for KTM 250/450/520/525 applications

Wiseco's CSK041 clutch springs are ideal for motocross, off-road, and enduro riders looking to restore or upgrade clutch performance. By preventing clutch slip and maintaining firm engagement, these springs help deliver consistent power transfer from engine to drivetrain.
