ACCOSSATO MASTER CYLINDER - CNC - FIXED LEVER; 17mm BORE 18 or 20 RATIO

FULL RACE SPEC CNC BODY!

The CNC Billet master cylinder, is Accossato's flagship master cylinder CNC machined from a single piece of solid 7075 Alloy billet. the CNC machining process allows for super critical tolerances, to give superior sealing properties, which particularly show up during hard track use. the Lever is adjustable for distance from the bar

It's important to select the correct bore and lever ratio, for your application. a larger lever ratio gives a firmer feel with less travel, at the expense of braking force, and vice versa

17mm bore master cylinders are suitable for bike with a single front caliper or twin calipers with no more than 4 pistons 30mm and below, the smaller lever ratio number will give a softer lever feel, and higher braking force for less lever pressure, the higher the number, the firmer the lever will feel and require more lever pressure for the same braking force

Some bikes with axial calipers, suffer from quite severe flex issues and the above rule doesn't always apply - generally we would advice going 1 ratio higher than would be selected for radial calipers

As with many things in life, there are always exceptions to the rules - if you are unsure and need specific advice please get in touch via the contact page

Note:

Aftermarket master cylinders use a different thread pitch banjo bolt, to OEM master cylinders, remember to add one to your order if needed!
