EBC Stainless Steel Brake Disc for BMW HP4 2012-2016 K69 S1000XR from 2020

EBC X/XC Series - Fully Floating Brake Discs for the Front Wheel

These brake discs replace many of the LS (Left) / RS (Right) brake discs and can be installed on both sides.

The steel used for the new EBC brake discs is a special stainless steel alloy with a higher friction effect than that of conventional heat-treated stainless steel brake discs. With a 10% improvement in friction effect, the braking force is further increased.

The weight of the new 'X' and 'XC' series is reduced by an additional 5-10% due to the 6-rivet system with a lightweight inner ring, which represents an improvement over conventional brake discs.

The new brake discs are equipped with EBC's unique and patented SD system, whose square rivets in the cutouts of the brake disc allow unrestricted expansion of the outer and inner rings under the heat generated during braking, without affecting the rivet connection.

Such an impairment occurs when the brake disc heats up due to heavy braking and the outer ring touches the (normally round) rivets that separate the outer ring from the inner ring. The new EBC system prevents this problem, which causes 100% of brake disc defects due to warping of the disc and vibrations.

What is the SD system? It is EBC's new square rivet system. This system completely prevents warping of the brake disc, increases the lifespan of the brake disc, and improves the consistency of braking performance.
