IRC Components Italy "M-Spec" 19x19 Brake Radial Master Cylinder is internally CNC Machined for Increased Braking, Feel, and Durability. Produced in Italy by a 25-year motorcycle braking systems technician with experience in the highest level braking systems used in World Superbike and MotoGP. For Trackday Riders and Racers looking for the Highest Feel and Stopping Power without paying a fortune for a Brembo 19mm RCS Radial Brake Master Cylinder or Brembo Front Brake Master Cylinder or compared to a lesser performing 19x18 Accosato Master Cylinder! Includes a Titanium M10x1.0 Banjo Bolt.
> The IRC Components 19x19 Master Cylinder has more brake feel than a traditional 19x18 setup, more brake power than a 19x20 setup, and has an in-between amount of travel required (with less force) between a longer travel 19x18 and shorter (more abrupt) 19x20 lever to achieve maximum braking power. It is incredible for high-performance street and race riders looking for two-finger braking without the worry of having their fingers pinned between the lever and handlebar. A typical 19x20 configuration has more braking power and requires less distance to completely pull in the lever vs. a 19x18 setup <
Revolutionary Technology: Where is it different from competitors? - Piston has an Innovative and Patented Teflon Ring that allows it to move without touching the Cylinder Wall. As a result, wear is virtually eliminated drastically improving the feeling of ease and forgetting the need of frequent inspection.
CNC - Billet vs. Forged - Cast: Master cylinders are manufactured using two processes and are designated as either CNC Billet or Forged. A Billet master is cut from a solid block of aluminum using a CNC machine. This machine is computer-controlled and can carve out masters to very precise tolerances. A billet master is very precise but also very expensive to manufacture. A forged master created by heating a blob of aluminum (known as an ingot) to a temperature where it is malleable (but not a liquid) and pressing it into a mould to form the final shape. (It's different from casting where the metal is heated into a liquid state and poured into a mould.) The forging process is relatively crude and may have imperfections such as air bubbles or rough surfaces. A forged master is not as precise or refined as a billet master but is much cheaper to manufacture.

Lateral Shims reduce Lever Axial Free Play for Outstanding Feel
Modification to the Lower Gasket reduces the "Empty Master Cylinder" effect
Folding: IRC Italy M-Spec masters are designed to absorb crash damage through a folding lever. This lever has a hinge in it which allows the lever to swing up in the event that the motorcycle gets dumped.
Rebuild Kits: easy available and can be installed by almost any rider even with limited mechanical experience, MOTO-D can rebuild your IRC Italy M-Spec Master Cylinder. Under Heavy Use Track and Race Riders can expect the need to rebuild every 5 years (due to CNC design there is no wear to the master cylinder wall) and possibly even longer.
The IRC Italy M-Spec Master Cylinder is not comparable to any radial pump on the market, guaranteed, designed, and produced in Italy for MOTO-D, you will be convinced that they are the best Master Cylinder on the market at any price.
