Choosing a radial caliper in a motorcycle, especially for the braking system, offers many advantages compared to a traditional or axial caliper.

Here are some reasons why a radial caliper can be a good option:

  1.  Better braking power: Radial calipers are designed to maximize possible braking power. They allow more effective deceleration of the motorcycle, especially at high speeds, by more efficiently transferring the braking force from the caliper to the wheel.
  2. Reduction of flexion: Radial calipers are mounted to reduce flexion, meaning the pressure applied on the brake pads is more uniform and direct. This allows better modulation of braking, which is important for sporty activities.
  3. Improved cooling: Generally, radial calipers have better ventilation and heat dissipation. This reduces the risk of overheating and loss of braking power by maintaining a more stable operating temperature of the brake pads.
  4. Better aesthetics: Compared to conventional calipers, radial calipers often have a more sporty and modern appearance, which can be an important criterion for some riders.
  5. Improved maneuverability: Radial calipers can enhance the motorcycle's maneuverability, especially in corners, by reducing flexion and more evenly distributing the braking force.
