Loved by racers worldwide, the Accossato 16PRS radial clutch 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 motorcycle riders who want to tailor the amount of force required on the lever to engage the clutch. Accossato has been producing Italian made sportbike components for original and aftermarket use since 1969.
This clutch 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 softer (15 mm), semi-firm (16 mm), or most responsive (17 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-15-16-17 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 hydraulic clutch master uses a 16 mm diameter piston and an upgraded racer's 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.
Accossato produces race-quality clutch 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.

Items Required to Complete Installation:
Accossato suggests using the Accossato 15 ml Clutch Reservoir Mounting Kit (P/N ACC-KITVP; sold separately) as it includes a reservoir, bracket, hardware and tubing.
The clutch master kit includes a single hole banjo bolt with two copper washers.
If you wish to retain the clutch micro-switch functionality, you will require a Single Hole Inline Pressure Switch, Banjo Bolt (P/N: ACC-ID001; sold separately).
If you intend to use your stock reservoir you will require a length of 6 mm Tygon 2375 Tubing and 2-3/8" Spring Clamps (all sold separately).
Dot 4 Brake fluid will be needed. Accossato suggests replacing all of the fluid in the system when you install the master.
