Product overview

When an engine is tuned or used with a heavy load, standard springs allow the clutch to slip and generate heat. These Si-Cr alloy springs increase clamp load by about 15 % while keeping lever effort usable, and their powder-coated finish resists corrosion in humid climates. Free length 38.0 mm, wire diameter 3.2 mm, sold in six-piece sets.

Suitable applications

  • Tuned engines
  • Loaded utility bikes
  • Racing applications
