Loved by racers worldwide, the Accossato 19x20 radial brake master cylinder for sportbikes feature a forged aluminum cylinder which is stronger and lighter than stock cast units for maximum reliability. The 19 mm piston is a perfect option for motorcycles with a double disc brake rotor setup. Accossato has been producing Italian made sportbike components for original and aftermarket use since 1969.
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.
Fixed / folding lever: 19 mm x 20 mm.
Material: Pressure forged aluminum.
Piston: 19 mm.
Disc application: Double.
Surface protection: Anodized / Painted.
The short length lever is a popular choice for riders who have smaller hands or wish for the lever to be accessed easily towards the center of the bike and for stunt riding.
The standard length RST lever features an anti-drag inlet hole machined into the lever end for the passage of air at high speed; this is a popular choice for track and race riders.
Exclusive three (3) year limited U.S.A. warranty.
Items required to complete installation:
Accossato suggests using the Accossato 30 ml Brake Reservoir Mounting Kit (P/N ACC-KITVG; sold separately) as it includes a reservoir, bracket, hardware and tubing.
The 19x20 brake master cylinder includes a double hole banjo bolt with three copper washers. This will work if you have two brake lines coming off the master cylinder. If you only have one line off the master you will need a M10x1.0 Single Hole Banjo Bolt (P/N ACC-MS2365; sold separately).
If you wish to retain brake light functionality you will require a Double Hole Inline Brake Light Pressure Switch Banjo Bolt (P/N ACC-ID002; 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. Do NOT use Dot 5.1.
