Yamaha BW'S / MBK Booster 50 2T Polini radial brake kit

Radial brake kit from manufacturer Polini for Yamaha BW'S / MBK Booster 50 2T.

To optimize the brake system on models such as MBK Booster or Yamaha BW's, the use of a radial brake caliper together with an oversized disc is a fundamental technical improvement. This Polini radial brake kit is designed to offer more precise braking control, reducing system fatigue and improving the dissipation of heat generated during prolonged braking.

The oversized brake disc allows for a greater contact surface, which reduces operating temperature and improves thermal stability. This is crucial to avoid problems such as brake "fading," a decrease in braking efficiency caused by overheating. Thanks to its optimized design, the disc better distributes the energy dissipated during braking, reducing the concentration of hot spots that can cause warping.

The 4-piston radial caliper improves the structural rigidity of the brake system by distributing the clamping force more evenly. Unlike conventional calipers, which apply pressure from a lateral angle, the radial caliper applies the braking force directly on the axis of the disc. This reduces torsion in the mounting structure and ensures a more consistent response during hard braking. In addition, the four pistons allow for more even contact between the brake pads and the disc, improving brake modulation and reducing excessive pressure at specific points.

With this Polini radial brake kit, you get a significant improvement in braking power, stability, and thermal resistance, ensuring optimal performance at all times.
