Accossato Fixed Brake Discs for Motorcycles and Scooters

Find the Accossato fixed brake disc compatible with your motorcycle or scooter. This section includes front and rear steel fixed brake discs developed as original replacement components for a wide range of motorcycle and scooter makes, models and production years.

Accossato fixed brake discs are designed to deliver reliable braking performance and precise fitment across a wide range of motorcycle and scooter applications. Manufactured from a single piece of steel, the braking surface and the mounting section form one solid component, without the floating bobbins used on floating brake discs.

What Is a Fixed Brake Disc?

A fixed brake disc is a brake disc in which the braking surface is directly connected to the section mounted to the wheel hub.

This design is widely used on front and rear applications, including road motorcycles, scooters, custom bikes and off-road models. Construction, dimensions and profile may vary significantly depending on the vehicle and the installation position.

A fixed brake disc should never be selected solely by its outer diameter. All mounting dimensions, fitment and compatibility specifications must match the motorcycle's braking system.

Finding the Right Fixed Brake Disc

Use the AG Moto vehicle selector by entering:

• make;
• engine size;
• model;
• production year.

After identifying the correct replacement brake disc, always compare the listed applications and technical specifications with the brake disc currently fitted to your motorcycle or scooter.

Always verify:

• front or rear application;
• outer diameter;
• inside diameter;
• braking surface thickness;
• number of mounting holes;
• mounting hole diameter and bolt pattern;
• offset;
• mounting side, where applicable;
• compatibility with the brake caliper and brake pads.

Motorcycles with the same commercial name may use different brake discs depending on the production year, version, market or equipment specification.

Front and Rear Fixed Brake Discs

The Accossato range includes front fixed brake discs, rear fixed brake discs and steel fixed brake discs developed for specific mounting positions depending on the application.

Do not install a front brake disc in place of a rear brake disc, or vice versa, based only on visual similarity. Diameter, thickness, offset, mounting dimensions and braking surface must all match the manufacturer's specifications.

For motorcycles equipped with twin front brake discs, also verify whether the product is sold individually or as a pair. If the price refers to a single brake disc, two compatible discs will be required to complete a twin-disc braking system.

Fixed or Floating Brake Disc?

On a fixed brake disc, the braking surface and the central mounting section form a single component.

On a floating brake disc, the braking surface is connected to the carrier by floating bobbins that allow controlled movement between the two parts.

The two designs should not be considered automatically interchangeable. The correct choice must always follow the motorcycle manufacturer's specifications or the requirements of the braking system configuration.

Brake Pads and Matching a New Brake Disc

When replacing a motorcycle brake disc, the condition of the brake pads should also be checked.

Brake pads that are heavily worn, damaged or already bedded into the previous brake disc may not make proper contact with the new component. The correct brake pad compound should be selected according to the application, intended use and the technical specifications of both the brake disc and the motorcycle.

After installation, the new brake disc and brake pads may require a gradual bedding-in period. Unless otherwise specified by the manufacturer, avoid aggressive braking during the initial kilometres.

When Should a Fixed Brake Disc Be Replaced?

A fixed brake disc should be inspected regularly and replaced when it reaches the minimum thickness specified on the component or in the manufacturer's technical documentation.

It is also important to check for:

• deep grooves;
• distortion;
• cracks;
• uneven wear;
• vibration during braking;
• damage to the mounting holes or mounting surfaces.

There is no universal replacement interval, as brake disc wear depends on riding style, motorcycle weight, brake pad compound, environmental conditions and braking system maintenance.

Installation and Safety

The brake disc is one of the most important safety components on any motorcycle or scooter. Correct installation is essential to ensure safe operation and reliable braking performance.

Installation should be carried out only after checking the cleanliness of the mounting surfaces, the condition of the fixing bolts and the correct tightening torque.

Before riding, always verify:

• correct brake disc installation;
• free wheel rotation;
• no interference with the brake caliper or brake pads;
• correct tightening of all fixing bolts;
• proper operation of the braking system;
• absence of abnormal vibration or noise.

Installation and final inspection should always be carried out by qualified personnel.
