Accossato Forged Radial Brake Master Cylinder With Folding Lever – 19Mm Bore, 18Mm Ratio

Description

Accossato Forged Radial Brake Master Cylinder 19×18 with Folding Lever – Ultimate Track & Street Braking

Upgrade to the Accossato Forged Radial Brake Master Cylinder 19×18 for superior, controllable braking performance. Features forged aluminum body, 19mm piston, 18mm leverage ratio, and a crash-resistant folding lever. Perfect for dual-disc sport bikes on both track and aggressive street use.

The Accossato Forged Radial Brake Master Cylinder with a 19mm piston and an 18mm lever ratio (19×18) is a premium braking component engineered for high-performance motorcycles, specifically those with a dual-disc front brake system. The body is crafted from high-strength forged aluminum, offering exceptional rigidity and reduced weight compared to standard components. This construction ensures minimal flex, delivering a consistent and immediate feel at the lever. The “radial” design optimizes force transmission, providing prompt and highly controllable braking under all conditions. The 19mm piston diameter is optimally sized for modern sport bikes utilizing twin calipers, ensuring sufficient fluid displacement for powerful stopping force. The 18mm leverage ratio strikes an excellent balance, offering a responsive yet manageable braking feel—highly recommended for dedicated track use but also suitable for aggressive and fast street riding. A standout feature is the folding (articulated) lever, made from CNC aluminum, designed to pivot upwards in the event of a crash or tip-over, significantly reducing the chance of breakage and allowing the rider to continue safely. All hardware, including screws and pins, are made from stainless steel for enhanced durability. This Italian-made master cylinder dramatically reduces the lever’s passive stroke, meaning less ‘dead space’ and a more immediate, direct connection to your braking system.

Best Uses

1. Sport Bikes/Superbikes: Ideal for high-performance motorcycles with dual-disc front brake systems (1000cc+ or aggressive 600cc).
2. Track Days & Racing: The 19×18 ratio is a popular choice for track use, providing powerful and predictable braking.
3. Aggressive Street Riding: Suitable for riders who demand maximum feel and performance for spirited road riding.
4. Braking System Upgrade: A significant performance upgrade over most Original Equipment Manufacturer (OEM) axial or radial master cylinders.

Key Features

1. 19mm Piston x 18mm Ratio (19×18): Optimal sizing for dual-disc motorcycle brake systems, offering powerful, controlled, and track-ready performance.
2. Forged Aluminum Body: High-rigidity construction (often hard-anodized) ensures minimal flex for a consistent, immediate, and direct braking feel.
3. Folding Lever: CNC-machined aluminum lever is designed to pivot upon impact, minimizing damage in a crash and preserving the functionality of the master cylinder.
4. Radial Design & Reduced Passive Stroke: Ergonomically superior design drastically cuts down the lever’s ‘dead space’ before engagement, resulting in highly prompt and predictable braking action.
5. Premium Italian Manufacturing: Engineered and made in Italy with high-quality components, including stainless steel hardware and race-grade seals for reliability and longevity.

Key Benefits

1. Superior Braking Control: Achieves a highly prompt and predictable braking response, allowing the rider to modulate pressure with greater precision.
2. Increased Safety & Reliability: The folding lever feature offers crash-resistance, protecting the master cylinder body and ensuring the bike remains rideable after a tip-over.
3. Enhanced Track Performance: The 19×18 ratio provides the leverage needed for powerful, consistent late-braking on the circuit.
4. Excellent Durability: Forged construction and stainless steel components provide exceptional strength, resistance to bending, and long-term reliability even under racing stress.
5. Direct Braking Feel: The short passive stroke translates into a more immediate, “connected” feel to the calipers, boosting rider confidence and feedback.
