Master Cylinder

Master Cylinder

The Accossato PRS (16) or (19) 17-18-19 radial brake master cylinder is ABE 61454-homologated, making it street-legal for the German market. It provides responsive and modular braking under all operating conditions.

The ergonomics of this radial master cylinder have been meticulously designed to ensure the best possible performance at all times. Furthermore, the new lever ergonomics integrate perfectly with the motorcycle's original dimensions and components.

The PRS 17-18-19 master cylinder is crafted from CNC-machined aluminium, offering excellent durability and a premium aesthetic finish that enhances the quality of your bike. Reduced weight, superior resistance to bending, and a shorter "dead stroke" (passive travel) during braking are just a few of the reasons to choose an Accossato radial master cylinder for your motorcycle.

Understanding 17-18-19

When describing a master cylinder, two main values are provided: 17-18-19.

The first number (16) or (19) represents the piston diameter in millimeters.

The second number (17-18-19) represents the lever pivot distance (offset).

Which configuration should you choose?

16 mm Diameter: Ideal for single-disc braking systems.

19 mm Diameter: Ideal for double-disc braking systems.

PRS 17-18-19 Pivot Distance: Suitable for all types of riding, as the offset is adjustable.
