Accossato Calipers: Italian Braking Excellence

For motorcycle enthusiasts and discerning riders who demand the utmost in braking performance and feel, the name Accossato resonates with Italian engineering prowess. Originating from Italy, a nation synonymous with automotive passion and precision, Accossato has carved a significant niche in the competitive world of motorcycle braking systems. Their components are not merely aftermarket upgrades; they are meticulously crafted pieces of engineering that have proven their mettle on the demanding arena of track sports competition, consistently enhancing a rider's connection with their machine. This article delves into the specifics of Accossato brake calipers, exploring their design philosophy, available variations, and how they contribute to a superior braking experience, alongside a broader look at their comprehensive braking solutions.

The Heart of the Braking System: Accossato Calipers

At the core of any effective braking system lies the brake caliper. This crucial component is responsible for gripping the brake disc, thereby converting the kinetic energy of the motorcycle into heat, slowing the vehicle down. Accossato understands this fundamental principle and has dedicated significant resources to developing calipers that not only perform exceptionally but also offer a tangible improvement in rider feedback. Their calipers are engineered to provide a precise and potent braking response, allowing riders to modulate their braking with confidence and control, even under the most demanding conditions.

Radial vs. Axial Mounts: Understanding the Difference

When discussing motorcycle brake calipers, a key distinction lies in their mounting style: radial and axial. Accossato offers both, catering to a wide array of motorcycle makes and models, as well as different performance preferences. Understanding the difference is crucial for selecting the right caliper for your needs.

Radial Mount Calipers

Radial mount calipers are the modern standard for high-performance motorcycles. In this configuration, the caliper bolts directly to the fork leg or swingarm, with the mounting bolts being perpendicular to the axle. This design offers several advantages:

• Increased Rigidity: The direct mounting reduces flex, leading to a more consistent and powerful brake application.
• Improved Braking Feel: Reduced flex translates to more direct feedback from the brake lever to the rider.
• Easier Pad Changes: Often, radial calipers allow for simpler access to the brake pads for quicker replacements.
• Optimised Lever Ratio: Radial calipers work in conjunction with radial master cylinders for a more progressive and controllable brake lever feel.

Accossato's radial calipers are a prime example of this technology. They are precision-machined, often from billet aluminium using CNC (Computer Numerical Control) machining, ensuring tight tolerances and exceptional durability. These are available in various offset configurations, such as the popular 100 mm and 108 mm off-set variants, which are designed to fit a wide range of performance motorcycles. The offset refers to the distance between the mounting points of the caliper. A critical development from Accossato is the new PZ010 caliper, specifically designed for the rigours of the British Superbike championship, featuring a 21 mm off-set. This highlights Accossato's commitment to developing cutting-edge technology for top-tier racing.

Axial Mount Calipers

Axial mount calipers, also known as conventional or P-type calipers, have been the standard for many years. In this setup, the caliper mounts parallel to the wheel axle, with the mounting bolts passing through the caliper body and into threaded holes in the fork leg or swingarm. While generally less rigid than their radial counterparts, axial calipers are still effective and are found on a vast number of motorcycles, from older models to many modern street bikes.

Accossato also produces high-quality axial calipers, ensuring that riders with bikes requiring this mounting style can still benefit from their engineering expertise. These calipers are designed to offer a significant upgrade over stock axial calipers, providing improved stopping power and better modulation.

Materials and Finishes: Craftsmanship in Every Detail

The quality of Accossato brake calipers is evident in the materials and finishes used. Many of their performance calipers are CNC-machined from high-grade aluminium alloys. This not only ensures strength and lightness but also allows for intricate designs that optimise fluid dynamics and heat dissipation. The finishes are not just for aesthetics; they often serve a functional purpose:

• Anodised Finishes: Provide corrosion resistance and can help dissipate heat. Accossato offers a range of colours for customisation.
• Polished Finishes: Can contribute to heat dissipation and offer a classic, high-quality look.
• Hard Coating: In some racing applications, a harder coating might be used for extreme durability.

The attention to detail in the manufacturing process ensures that each caliper is a precision instrument, ready to perform under pressure.

Beyond Calipers: The Complete Accossato Braking Ecosystem

While brake calipers are a focal point, Accossato's commitment to enhancing motorcycle braking extends to a comprehensive range of related components. To achieve optimal braking performance, all elements of the system must work in harmony. Accossato provides:

Radial Brake Master Cylinders

Complementing their radial calipers, Accossato offers high-quality radial brake master cylinders. These are precision-engineered to work seamlessly with their calipers, offering:

• Enhanced Lever Feel: The radial design pushes the piston directly into the brake fluid, reducing sponginess and providing a more direct connection.
• Adjustability: Many Accossato master cylinders feature adjustable lever reach and ratio, allowing riders to fine-tune their braking input.
• Increased Braking Power: The efficient design can contribute to greater hydraulic advantage.

These master cylinders are crucial for unlocking the full potential of performance braking systems.

Motorcycle Brake Pads

The correct brake pads are essential for effective braking. Accossato provides high-quality brake pads designed for various motorcycle brands and models. Their pads are formulated to deliver:

• Powerful and Reliable Braking: Offering consistent performance across a range of temperatures.
• Durability: Engineered to withstand the rigours of riding, from spirited street use to track days.
• Material Options: Accossato likely offers different pad compounds (e.g., sintered, organic, ceramic) to suit different riding styles and conditions.

The price of brake pads can vary significantly depending on the specific motorcycle model and the compound of the pad, but Accossato aims to provide excellent value for their performance.

Brake Discs

Brake discs are the surface that the caliper pads act upon. Accossato brake discs are manufactured from premium materials, prioritising:

• Optimal Heat Dissipation: Crucial for preventing brake fade during prolonged or hard braking. Perforated or wave designs often aid in this.
• Durability and Wear Resistance: Ensuring a long service life and consistent performance.
• Material Quality: High-carbon steel or other advanced alloys are typically used.

Available for a wide range of motorcycles, the specifications and design of the brake disc will influence its price, with performance-oriented discs often commanding a higher cost.

Brake Hoses

Stock rubber brake hoses can expand under pressure, leading to a less precise brake feel. Accossato offers braided brake hoses as a superior alternative:

• Braided Construction: Typically made with a stainless steel outer braid and a PTFE inner liner, these hoses resist expansion under pressure.
• Improved Brake Feel: The lack of expansion results in a firmer, more responsive brake lever.
• Durability and Colour Options: Braided hoses are more resistant to abrasion and damage than rubber hoses. Accossato offers these in a variety of colours, allowing for customisation and easier identification of front and rear lines.
• Complete Fittings: Accossato hoses come complete with all necessary fittings and banjo bolts, ensuring a straightforward installation.
