Accossato Radial Brake Master Cylinder PRS 19x17-18-19 - Adjustable Ratio & Folding Lever | Race Performance
Unlock superior stopping power with the Italian-made Accossato PRS 19x17-18-19 Radial Brake Master Cylinder. Features a 19mm piston, adjustable 17-18-19mm ratio, and folding lever for customized, precise control on track or street.
The Accossato Radial Brake Master Cylinder PRS 19x17-18-19 with Folding Lever is a premium, high-performance upgrade engineered in Italy for demanding riders. Designed to deliver prompt, controllable, and predictable braking under all conditions, this master cylinder dramatically enhances your motorcycle's front braking system.
Key Technology: PRS (Power Ratio System) Adjustability The standout feature is the PRS adjustable lever pivot distance, offering three ratios: 17mm, 18mm, and 19mm. This allows you to fine-tune the master cylinder's feel and power output.
-
17mm (More Power): Provides a quicker, more forceful brake response.
-
19mm (More Feel): Offers a softer, more progressive feel with greater modulation.
-
18mm (Balanced): The perfect middle ground for versatile riding.
Race-Ready Design & Construction The master cylinder body is precision-machined from CNC aluminium for exceptional strength, lightweight design, and superior resistance to bending during hard braking. The 19mm piston is specifically chosen for optimal performance with dual-disc braking systems (common on superbikes and high-performance street bikes).
Reduced Passive Stroke Accossato has engineered this unit to achieve the shortest passive stroke possible. Compared to many other radial master cylinders, the space between initial lever movement and actual pad engagement is reduced by over 50%, providing an immediate and exceptionally "ready to brake" feel.
The included lever is a robust folding (articulated) type, a crucial feature for minimizing damage in the event of a crash or tip-over.
Best Uses
-
Track Days & Racing: Ideal for competitive environments where precise, high-performance, and adjustable braking response is critical.
-
High-Performance Street Riding: Perfect for riders with dual-disc superbikes or sportbikes seeking a significant upgrade in braking feel and control over stock components.
-
Custom/Naked Bike Builds: An excellent choice for custom projects demanding a premium, high-quality, and visually striking brake system component.
-
Any Dual-Disc Motorcycle: Optimally paired with motorcycles featuring dual front brake discs (where a 19mm piston diameter is recommended).
Key Features
-
PRS (Power Ratio System) Variable Ratio: Quickly adjustable lever pivot distance (17mm, 18mm, 19mm) to tailor brake feel and power output to rider preference or riding conditions.
-
19mm Piston Diameter: Optimized for powerful and effective use on motorcycles equipped with dual-disc front braking systems.
-
CNC-Machined Aluminium Body: Provides superior strength, reduced weight, and natural anodizing for long-lasting durability and high-end aesthetic.
-
Folding (Articulated) Lever: Designed to pivot up and away in a crash, significantly reducing the chance of snapping the lever.
-
Ultra-Short Passive Stroke: Precision engineering minimizes 'dead travel' or free play in the lever, ensuring immediate and responsive braking action.
Key Benefits
-
Customizable Braking Performance: The PRS system allows you to instantly change the braking ratio (feel vs. power), adapting the bike to the track, road, or personal preference.
-
Enhanced Safety & Control: Delivers predictable, reliable, and more powerful braking, giving the rider maximum confidence under extreme braking scenarios.
-
Immediate Response: The ultra-short passive stroke translates to a highly responsive and aggressive brake feel, drastically reducing lever travel before braking begins.
-
Crash Damage Mitigation: The folding lever design protects the master cylinder assembly from catastrophic damage in the event of a minor tip-over or fall.
-
Premium Italian Quality: Fully Made in Italy with high-grade components (stainless steel screws, Formula 1 compound seals), ensuring exceptional longevity and race-proven performance.
