Derived directly from WorldSBK, BSB and BMW HP4 Race competition, the Brembo GP4-PR Monoblock brake caliper is the right-hand unit engineered for riders who demand uncompromising stopping power at the absolute limit of track performance. With titanium pistons, a central bridge monoblock body and a pedigree forged in professional racing series, this caliper represents the pinnacle of Brembo's racing brake technology.

Key Features

  • Monoblock aluminium construction with a central bridge delivers exceptional torsional rigidity and consistent pedal feel under repeated hard braking
  • Four titanium pistons (2x 32 mm, 2x 36 mm) reduce unsprung thermal mass and resist heat fade during extended track sessions
  • Race-proven in WorldSBK, BSB and BMW HP4 Race — the same caliper trusted by professional teams at the highest level of superbike competition
  • Right-hand caliper with 108 mm radial mounting pitch, designed exclusively for forks with a 108 mm bolt spacing
  • 21 mm offset optimises disc contact geometry for maximum modulation and braking stability
  • Approximate weight of 630 g per caliper keeps unsprung mass to a minimum without sacrificing structural integrity

Race-Bred Engineering

The GP4-PR sits at the top of Brembo's radial caliper range. Its monoblock aluminium body is machined from a single billet, eliminating the flex inherent in two-piece designs and translating every degree of lever input into precise, linear deceleration. The central bridge further stiffens the caliper under the extreme hydraulic pressures generated during late braking at race speeds. Titanium pistons are standard fitment — not an upgrade — underscoring the no-compromise philosophy behind this part.

Trackday & Competition Use

The GP4-PR is developed exclusively for closed-circuit use. It carries no road type-approval and must not be fitted to road-registered motorcycles. For trackday riders stepping up to professional-grade hardware, or race teams seeking a proven WorldSBK-specification caliper, the GP4-PR delivers the confidence to push braking points deeper and later than any OEM alternative.
