Customizing Harley Motorcycle Brake Discs Guide​

When customizing your Harley-Davidson motorcycle brake rotors, it’s crucial to make sure you choose the one that best suits your motorcycle and riding needs. This involves several key factors, from material selection and dimensional matching to performance requirements, which all need to be carefully considered. Below is a closer look at these key factors.

1. Material selection

The material of the brake disc directly affects its performance and service life. Common materials include high-performance steel, aluminum alloys, and carbon fiber. High-performance steel has high strength and wear resistance, making it suitable for high-load and high-speed riding situations. Aluminum alloy is relatively light, which helps reduce the weight of the vehicle and improves handling performance. Carbon fiber is known for its excellent lightweight and strength, but its cost is also relatively high. When selecting materials, factors such as performance, weight and budget need to be considered.

2. Size Match

Brake rotors must be sized to match your Harley wheels and braking system. This includes the diameter and thickness of the brake disc as well as the location and size of the mounting holes. Wrong size selection can lead to installation difficulties, poor braking performance and even safety hazards. Therefore, when customizing brake discs, it is important to provide the exact model and year of your motorcycle to ensure that the disc dimensions are a perfect match for your motorcycle.

Generally speaking, the size of Harley motorcycle brake discs will be in the following range:

  • Diameter: Typically between 11.5 inches and 13 inches, depending on model and year.
  • Thickness: Typically between 0.2 inches and 0.3 inches, also varies by model and year.

3. Performance requirements

Different riding needs have different performance requirements for brake discs. For example, if you regularly drive long distances at high speeds or need to brake frequently, you may want to choose brake discs with higher resistance to heat and wear. For those who mainly ride in the city or on flat roads, they may pay more attention to the smoothness and comfort of the brake disc. So when customizing your brake rotors, be clear about your riding needs so you can choose the rotor that best suits your performance characteristics.

4. Brand and manufacturer selection

Choosing a well-known brand and experienced manufacturer is also key to ensuring the quality of the brake disc. Well-known brands usually have stricter quality control and more advanced production processes, allowing them to provide more reliable and superior-performing brake discs. At the same time, experienced manufacturers can better understand the characteristics and needs of Harley motorcycles, thereby providing you with more suitable customized solutions.

5. Security Considerations

As a key component of the motorcycle braking system, the quality and performance of brake discs are directly related to riding safety. Therefore, when MPM customizes brake discs, it is very important to ensure that the materials, dimensions and performance selected meet safety standards. In addition, professional guidance must be followed during the installation process to ensure that the brake disc is installed correctly and adjusted to its optimal condition.

What are Harley floating rotors?

Harley floating rotors refer to a specific type of brake rotor design used on Harley-Davidson motorcycles. The term “floating” refers to the way the rotor assembly is mounted to the hub.

In a floating rotor setup, the rotor is not firmly fixed to the hub but is allowed to “float” or move slightly within its mount. This movement is usually achieved by using bushings or bearings that allow a small amount of lateral play.

The main advantage of this design is that it helps reduce braking torque and heat transfer to the hub and spokes. When braking, force is primarily absorbed by the rotor itself rather than being transferred to the hub and spokes, which helps maintain the integrity and longevity of these components.

Additionally, floating rotors provide more consistent braking feel and performance because they are less likely to be affected by changes in wheel temperature or thermal expansion.

It’s worth noting that floating rotors are not unique to Harley-Davidson motorcycles and can be found on other makes and models. However, they are a common feature on many Harley models and are often appreciated by riders for their enhanced braking performance and durability.

FAQ About Harley Davidson Brake Rotors

Yes, motorcycle rotors, including those from Harley-Davidson and other brands, can be made in China. China has a large and developed manufacturing base, and MPM is a company specializing in the production of various motorcycle parts including rotors.

These Chinese manufacturers are often capable of producing high-quality rotors that meet or exceed industry standards. They use advanced manufacturing techniques and materials to ensure durability, performance, and safety.

Additionally, many global brands may source their rotors from China but still maintain strict quality control measures to ensure the final product meets their standards. So while the rotors may be made in China, the brand itself usually ensures that they meet its high quality standards.

To sum up, motorcycle rotors can indeed be made domestically, but it is crucial to choose a reliable supplier that can guarantee quality and safety.

Aftermarket motorcycle rotors and OEM (original equipment manufacturer) rotors each have their own advantages and disadvantages, and whether one is “better” than the other depends on specific criteria and the needs of the individual rider.

OEM rotors are designed and manufactured by the motorcycle’s original manufacturer and are custom-made to fit the bike’s original specifications. They are usually the most compatible with the other components of the bike and are usually backed by a manufacturer’s warranty. OEM rotors also tend to have a more consistent fit and finish because they are manufactured to exacting standards.

Aftermarket rotors, on the other hand, offer a wide range of options and customization. Riders can choose from rotors with different materials, finishes and performance characteristics to suit their riding style and needs. Aftermarket rotors can also cost less than OEM rotors, making them a more affordable option for some riders.

However, it’s worth noting that not all aftermarket rotors are created equal. Some may be of lower quality or may not fit the OEM rotor, potentially affecting performance and safety. Therefore, when considering aftermarket rotors, it’s crucial to research and choose reputable brands and suppliers.

All in all, whether aftermarket or OEM rotors are better depends on the specific needs and preferences of the rider. OEM rotors offer a consistent fit and finish and are backed by the manufacturer’s warranty, while aftermarket rotors offer customization and potentially lower costs, but require careful selection to ensure quality and fit.

Yes, Harley-Davidson has manufacturing operations in China. For example, Harley-Davidson cooperates with China’s Qianjiang Motorcycle to produce models such as the Harley-Davidson X350. This motorcycle is manufactured by Qianjiang Factory and sold in the Chinese market. However, it should be noted that although some Harley-Davidson motorcycles are produced in China, the brand’s core technology and design usually remain at Harley-Davidson’s main production base. Therefore, although produced in China, these motorcycles still maintain Harley-Davidson’s consistent high quality and unique style.

In addition, Harley-Davidson also has trading companies in China, such as Harley-Davidson (Shanghai) Trading Co., Ltd., which is responsible for sales and operating activities in the Chinese market.
