Loved by racers worldwide, the Accossato 16PRS radial brake master cylinder for sportbikes feature a folding, standard length RST lever with anti-drag inlet hole. The forged aluminum cylinder is stronger and lighter than stock cast units for maximum reliability. The variable lever ratio of the 16PRS makes it the perfect option for motorcycles with a single 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 (18mm), 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 16x-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 16mm diameter piston and a upgraded racers folding, standard length RST lever which features an anti-drag inlet hole machined into the lever end for the passage of air at high speed. This is the most popular choice for serious street and racetrack riders.
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.
