Brake Discs

S3 Performance motorcycle brake discs are manufactured using 420 stainless steel. 420 is far better suited to brake disc applications thanks to its higher carbon content when compared to 410 grade.. When fully hardened it is the hardest of the family of stainless steels. The addition of carbon content gives the brakes discs better braking performance and a longer life. Since asbestos was banned from the manufacture of brake pads, many pads now contain some steel content causing premature disc wear. S3 Performance brake discs are designed with this issue in mind.

All S3 floating brake discs for road bikes use 7075 alloy carriers which is very strong.. The use of 7075 alloy allows for high quality anodisation and low weight. All rivets/buttons used on S3 brake discs are stainless steel.

The use of high quality metals and machining ensures that S3 brake discs offer excellent stopping power for both road and off road bikes. The slotted design ensures a more even wear as opposed to drilling which can often lead to a waved effect across the surface of the disc. All S3 Motorcycle brake discs are backed by a 24 month warranty for all road registered bikes. All discs carry the required minimum thickness markings essential for road registration.
