EBC Floating Brake Discs are designed to provide enhanced braking performance and reliability over standard fixed rotors. The floating design uses bobbins to connect the stainless steel friction ring to a lightweight alloy center, allowing controlled lateral movement. This helps accommodate thermal expansion under heavy braking and reduces the risk of rotor warp or brake judder.

Manufactured from premium stainless steel, each disc is precision-machined and heat-treated for strength, durability, and consistent friction performance. The alloy center reduces unsprung weight, improving handling response while maintaining structural integrity.

These discs are suitable for a wide range of road and light sport motorcycles where OE-style floating rotors are fitted. They provide smooth, predictable braking, resist corrosion, and are produced to exact fitment specifications for straightforward installation.

Feature Benefits

  • Floating disc design with a number of bobbins.
  • Stainless steel friction ring with alloy center hub.
  • Allows controlled thermal expansion to reduce distortion.
  • Precision-machined and heat-treated for durability.
  • Slight weight saving for improved handling.
  • Direct OE replacement for floating disc-equipped motorcycles.
  • Reliable, smooth braking for road and light sport use.

Floating discs deliver the benefits of thermal stability, reduced judder, and improved rotor longevity while maintaining dependable braking performance for everyday and spirited road riding.
