On Omnia Racing, you can find a dedicated category to purchase front and rear motorcycle brake master cylinders, including radial, axial and tangential master cylinders, suitable for road bikes, sport bikes, motard, enduro, cross, custom motorcycles and maxi scooters. Solutions are available for road, sport and racing use, with different piston sizes such as 11, 12, 13, 14, 15, 16, 17, 18, 19 and 20 mm, allowing you to match the master cylinder response to the characteristics of the brake calipers and overall braking system.

Among the most appreciated brands by motorcyclists, you will find Brembo Racing, a benchmark for high-performance radial brake master cylinders designed for track and competition, Brembo Strada, ideal for reliable upgrades on road motorcycles, Accossato, widely chosen for sport radial master cylinders with an excellent balance between performance and control, Discacciati, a technical brand appreciated in racing builds, Braking, specialized in advanced braking components, and Nissin, known for reliability and widely used in OEM systems.

Radial vs axial brake master cylinder: which one to choose

The difference between a radial brake master cylinder and an axial brake master cylinder lies in how the force is transmitted to the internal piston. Radial master cylinders are commonly used on sport and racing motorcycles because they offer greater precision, more direct response and improved pressure control during heavy braking.

Axial master cylinders, on the other hand, are widely used on road bikes and provide a progressive, reliable and user-friendly braking response. The choice should not be based only on performance, but also on caliper type, piston size, riding style and desired lever feel. A racing radial master cylinder can deliver excellent performance on track, but it must be properly matched to the specific braking system.

Power, feel and control through the master cylinder

The motorcycle brake master cylinder plays a crucial role in the overall braking feel. A well-chosen component provides a more precise lever, consistent response and greater confidence under braking. Braking performance depends on the balance between master cylinder, calipers, discs, pads, brake lines and brake fluid.

A correctly sized master cylinder improves braking power without compromising control. Modulation is equally important: the rider must be able to finely adjust braking force, especially during corner entry, on variable surfaces or in track conditions. The best result always comes from the correct pairing between master cylinder and calipers.

How to choose the right motorcycle brake master cylinder

A motorcycle brake master cylinder should be selected based on caliper type, number of pistons, piston diameter, intended use and desired lever feel. It is also important to verify compatibility with brake lines, fluid reservoirs, lever assemblies and available space on the handlebar.

What does 19x18 or 19x20 mean?

In a 19x18 or 19x20 brake master cylinder, the first number refers to the piston diameter, while the second indicates the lever ratio (pivot distance). One configuration may prioritize modulation, while the other provides a more immediate and aggressive response. Adjustable master cylinders allow riders to fine-tune the feeling according to their preferences.

Can you install a racing master cylinder on a road bike?

Yes, but compatibility must be carefully checked. A racing brake master cylinder that is not correctly sized can result in overly aggressive braking or reduced modulation. It is essential to consider calipers, brake lines, reservoir, lever setup, handlebar space and real riding conditions.

Is the rear brake master cylinder important?

Yes. The rear motorcycle brake master cylinder contributes to overall bike control, especially during manoeuvres, sport riding, motard use and stability management when entering corners. As with the front system, it is important to choose a component compatible with the braking system and intended use.

To achieve optimal braking performance, motorcycle brake discs and motorcycle brake pads must also be considered, as power and feel depend on the balance between control input, friction and braking surface. For a more refined riding experience, upgrading motorcycle brake and clutch levers can further improve ergonomics and control at the handlebar.

On Omnia Racing you can find radial and axial brake master cylinders from the best brands in the industry, with solutions designed for road, sport and racing applications.
