Machined from solid
Just like Brembo calipers used in MotoGP and Superbike World Championships, the
innovative GP4-MS caliper - for bikes with 100mm centres - is manufactured from aluminium
machined from a solid block.
Compared to braking components manufactured by casting, machining from solid allows the
use of materials with better mechanical characteristics, greater resistance to high
temperatures and, consequently, improvements to the performance of the entire braking
Unlike models in the previous GP4 range, the Brembo GP4-MS combines machining from
solid with monobloc technology, i.e. the use of a single block of aluminium – offering a new
design choice for motorcycle calipers in road applications.
This process was achieved by perfecting the use of topological optimisers, software derived
from 40 years of Brembo victories in the premier World Championship class. This computer
program has made it possible to optimise the shape of the caliper body.
The entire process
ensures exceptional rigidity, unprecedented lightness and less deformation at high
In common with its competition calipers, the Brembo GP4-MS also has nickel surface
finishing. In addition to attractive styling, this process has made it possible to comply with
strict manufacturing tolerances, to the benefit of performance and operating precision.
By fitting a double seal, one inside the piston and one acting as a dust cover, the Brembo
caliper ensures maximum on-road freedom without the need for the regular checks
characteristic of racing calipers.
