From China A motorcycle brake disc, also known as a rotor or brake disc rotor, is a crucial component of the braking system in motorcycles. It is typically a circular metal disc that is mounted on the wheel hub or axle of the motorcycle. When the rider applies the brakes, the brake pads come into contact with the disc, generating friction and slowing down or stopping the motorcycle. Here are some key features and characteristics of motorcycle brake discs: 1. Material: Brake discs are commonly made of high-quality cast iron or, in some cases, stainless steel. Cast iron discs are more common due to their excellent heat dissipation properties and cost-effectiveness. Stainless steel discs are often used in high-performance motorcycles as they offer better corrosion resistance and weight reduction. 2. Design: Brake discs usually have a flat, circular shape with cooling holes or slots on their surface. These features help dissipate heat generated during braking, prevent brake fade, and maintain consistent performance. The pattern and arrangement of the holes or slots can vary depending on the manufacturer and specific model. 3. Size: The size of a motorcycle brake disc can vary based on the motorcycle's weight, power, and intended usage. Larger and thicker discs are typically found on heavier bikes or those designed for high-performance applications. The diameter and thickness of the disc play a role in determining the braking force and heat dissipation capacity. 4. Mounting: The brake disc is attached to the motorcycle's wheel hub or axle using mounting bolts. The number and arrangement of mounting points may vary depending on the motorcycle's design. Some motorcycles may have multiple discs on the front wheel for enhanced braking performance. 5. Floating or Fixed: Brake discs can be either floating or fixed. Floating discs have some degree of lateral movement, allowing them to self-align with the brake caliper and reduce the possibility of brake judder or uneven pad wear. Fixed discs, on the other hand, are rigidly attached to the wheel hub or axle. 6. Maintenance: Brake discs require regular inspection to ensure they are in good condition. Over time, the disc's surface may wear down due to the friction caused by the brake pads. Excessive wear or damage to the disc, such as warping or cracking, may require replacement. It's important to note that specific motorcycle models may have unique brake disc designs or materials, so it's always advisable to consult the motorcycle's manufacturer or refer to the owner's manual for detailed information about the brake discs used on a particular bike. ========== Model Name : 12-BF111 Material Type : 410DB Stainless Steel Origin : Mainland China
