The GP4 caliper family has been completed with the arrival of the new Brembo GP4-rr, the
ultra-high-performance monobloc racing caliper.
The new Brembo GP4-rr takes its inspiration from the monobloc caliper
developed for MotoGP and makes it available to the general public, exclusively for use on
the track.
The all-new Brembo GP4-rr caliper is presented with a totally different look, inspired by the
lines and technologies of Brembo’s futuristic racing calipers and echoing the design of the
GP4-ms, the company´s first monobloc caliper made from a single piece, which is also
available for road use.
With the aim of optimizing stiffness and guaranteeing low weight, the new Brembo GP4-rr
caliper is completely machined from billet with the help of the latest CAD/CAM technology,
resulting in a leading mass to rigidity ratio in its category. In addition, thanks to the use of
simulation software it was possible to optimize the shape of the caliper body, revolutionizing
the typical style of competition calipers and moving the product’s technical and performance
levels even higher.
The Brembo GP4-rr monobloc caliper comes with a hard-anodized finish, a treatment
developed for racing competition that prevents wear on the caliper body, guaranteeing
performance over time.
The component is completed by four, titanium pistons of 32-36mm diameter. It can also
accommodate brake pads with an increased surface area compared to the previous version,
further increasing braking performance.
Like all Brembo racing components, the caliper is sold without pads and comes complete
with all the hardware required for assembly, plus the relevant instructions. The kit is also
enhanced by the same heat-transfer adhesives used in MotoGP, allowing riders to check the
operating temperature reached by the calipers after each session.
