CNC Billet-machined 2-piece calipers.
The caliper body is machined entirely from billet aluminium and comprises of two mechanically linked parts. 
These calipers are then nickel cadmium coated. This process has been derived from years of MotoGP experience and success. From this process even tighter tolerances are achieved in the caliper construction and performance.

Features the use of 32mm pistons which is oversized when compared to most OEM calipers. 
Brembo thermo-labels that read caliper temperature are also supplied with this kit as used in professional racing worldwide.

These calipers are interchangeable with most common Japanese bikes without any modification.  
​Brembo sintered brake pads are included.

  • Japanese model bikes: 108mm
  • European model bikes: 100mm 
  • Yamaha YZF-R1 09 - 14 : 130mm

Technical Information

Advanced geometries used in caliper body design with increased caliper body stiffness thanks to the triple bridge. Special research attention was dedicated to achieve high braking power and rigidity values, which were achieved thanks to meticulous design and by using carefully selected raw materials and the latest metalworking technology. ​This model, for the first time, have surface finishing borrowed from MotoGP bikes: the Nickel coating not only ensures an attractive look but also made it possible to perfect the already tight machining tolerances, to the benefit of operating performance and precision.
