A brake master cylinder obtained through forging dedicated to those who love the thrill of riding on the track. Forging is a process of plastic deformation of metals which increases mechanical resistance and consequently the final quality. Absolutely reliable, this brake master cylinder allows maximum readiness and perfectly modulable braking in any conditions of use with excellent linearity between the force the rider applies to the lever and the braking response, thereby achieving an extraordinary braking feeling. The brake master cylinder uses a 19 mm diameter piston, double disc, a lever centre distance of 18. A laser marking indicates the diameter of the piston and the lever centre distance.
