⚠ Brake parts are caliper-specific. The same model can use different calipers by trim or year (base vs SP, ABS, Brembo vs stock), and catalog data isn't always exact. Confirm this fits your bike's actual caliper before ordering.

  • Helps reduce rotor distortion, brake judder, and uneven wear under heavy braking.
  • Premium stainless steel construction delivers excellent durability and corrosion resistance.
  • Lightweight construction contributes to improved handling and reduced unsprung mass.
  • Precision-machined and heat-treated for strength, reliability, and long service life.
