These are the top of the line billet or CNC radial master cylinders from Accossato.  Machined from a solid piece of high grade billet alloy (as appossed to the forged version)

These are the professional level units for top racers, designed and manufactured in Italy.

The fixed ratio billet Accossato radial master cylinders are available in a number of fixed distances and bore diameters.

The selection of the correct piston size is a ratio between the cylinder and the caliper pistons and we are happy to guide people on this if you are unsure which model to select please contact us..

Thread size for brake line connection is M10x1.0 mm.  This may require a new banjo bolt depending on what your current brake set up has.  Race Supplies has both single and double banjo bolts in stock.

As standard Race Supplies stocks these with Black levers but they are available in Red, Blue, Green, Gold, Orange,Titanium and Silver. From time to time we do have some colour options available, please ask if you require something other than black

Top level road racers in New Zealand who have used other Italian made radial master cylinders have a very clear preference to the Accossato unit.  They say they get a improved feel on the brakes and a more consistant brake over the toughest races at the NZSBK series.
