The Suzuki GSX-R1000 remains true to the Brembo M4.32 radial caliper, a monobloc caliper with four 32 mm pistons and a 108 mm inter-axle. This Hamamatsu super sport bike is equipped with 320 x 5 Brembo Pin&Bar front discs, which use five bushes and five mounting planes to separate axial positioning (assigned to the bushes) and torque transmission (assigned to the axial planes) allowing for a reduced number of bushes, which in turn reduces temperature-dependent disc deformation and increases disc durability.
Usually it's the bushes (Pins) that carry out both functions, but that leads to a highly concentrated level of stress that increases the risk of deformation in the braking system components. With the use of the axial planes (Bars), the portion of the braking surface that enters the hat, the braking forces are transmitted to the hat by the braking surface in a more homogeneous manner.
Through a mix of these two components, accomplished through Pin&Bar discs, a brand new product for the world of motorcycles, there is more floating in both directions. The innovative Pin&Bar disc therefore allows for better discharge of the braking torque and discs that last for more kilometres travelled.
