Find other: Accossato Brake Master Cylinders
Loved by racers worldwide, the Accossato 17PRS radial brake master cylinder for sportbikes features a folding, short length lever or folding, standard length RST lever. The forged aluminum cylinder is stronger and lighter than stock cast units for maximum reliability. The variable lever ratio of the 17PRS makes it the perfect option for motorcycles with a double disc brake rotor setup since it allows the rider to tune up or down the brake feel and response to meet their individual riding style. Accossato has been producing Italian made sportbike components for original and aftermarket use since 1969.
This brake master cylinder has the revolutionary Accossato PRS system which allows the rider to make tool-free adjustments of the lever center distance selecting between the moderate (17 mm), firm (18 mm), or most responsive (19 mm). The advantage of the Accossato PRS comes from the relationship of the piston which is kept "in-axis" (meaning on a "straight line") as it acts on the position of the fulcrum during all lever adjustments. For this reason, the power of the Accossato PRS 17x-17-18-19 is an upgrade over other variable distance master cylinders. This technology was invented by Accossato, is not found on the RCS, and guarantees a more precise, immediate, and powerful feel with reduced wear on the internal gasket, piston, and cylinder wall.
This brake master uses a 17 mm diameter piston and a upgraded racer's folding, short length lever or folding, standard length RST lever. The short lever is a popular choice for riders campaigning Yamaha R6 and Yamaha R1 sportbikes who have smaller hands or wish for the lever to be accessed easily towards the center of the bike and for stunt riding.
Accossato produces race-quality master cylinders and braking components using a 100% quality-control process mandating all core components to be inspected under a microscope before assembly, pressure calibrated, and vacuum tested upon final assembly.
