Types of Brake Discs and Their Advantages

Have you noticed the different brake discs available for motorcycles? The various shapes and sizes of these components have a purpose: they respond to the different needs of each segment. For example, floating discs are ideal for sport bikes thanks to their mechanism that reduces vibrations. Oversized discs are perfect for track riding because they increase braking power, while drilled and wave-style discs help prevent overheating. Today, at NG BRAKES, as brake disc experts, we’ll walk you through the main types and their advantages.

The most common and well-known brake discs are made of a steel rotor with holes that mounts on the bike’s wheel hubs. It works together with a brake caliper with one or more brake pads which, when you pull the lever, press against the disc to slow the wheel down progressively in a consistent and safe way. The technology used today in the two-wheel sector has driven the evolution of this component, creating new and varied types that adapt to the specific needs of each rider and improve their bike’s performance. Among the different types, you’ll find:

Drilled brake discs

Drilled brake discs, as the name suggests, feature holes across their surface to dissipate heat more efficiently, improving braking performance in all conditions. In addition, the holes help remove water and debris, which is especially beneficial in wet conditions.

Floating brake discs

Floating brake discs are built in two pieces: an inner carrier, which is bolted to the bike, and an outer ring, which is the part that contacts the caliper. These parts are separated by a tiny clearance to allow limited axial movement, helping correct small misalignments between the caliper and the disc that can occur during braking. This reduces vibrations and improves lever feel, significantly enhancing performance, especially in extreme conditions. These models are common on sport bikes because their advanced design reduces the risk of warping even under higher temperatures and ensures more precise, effective braking.

Oversized brake discs

For riders who regularly take their bike to the track, the best option is oversized brake discs. They’re called oversized because they have a larger diameter than stock discs, which provides greater braking power. This is because the larger size increases the leverage between the disc’s braking surface and the wheel hub, enabling stronger braking force.

Wave brake discs

Wave brake discs are known for their wavy or scalloped outer edge. This means the outer edge of the disc is not constantly in contact with the caliper, creating a subtle “up-and-down” effect that helps prevent overheating.

At NG BRAKES we offer quality brake discs across all of these types for a wide range of motorcycle models. If you want to check them out, simply visit the “Catalog” section of our website and filter by your bike model to see all available options.
