A monobloc radial caliper machined from billet, designed around the HYCTION carbon-ceramic disc to ensure power, modulation, and consistent lever feel even when performance is pushed to the limit.
No compromises
Built like in MotoGP
Just like in competitions, the caliper is machined from billet: a choice that speaks of stiffness, precision, and build quality. Thermally optimized, it incorporates fins to sustain performance when temperature becomes a key factor.
Dedicated brake pads
GP4‑HY works with brake pads developed to interact ideally with the HYCTION disc. This is where technology becomes performance: stability, modulation, confidence.
Differentiated pistons
Pistons with diameters of 30 and 34 mm, designed to combine power and control, offering a progressive and consistent response.
Part of a system, protagonist in the result.
In supersport motorcycles, the difference is made in the most critical moments. GP4-HY is the caliper designed to work in symbiosis with the HYCTION carbon-ceramic disc, turning the most demanding braking into control, precision, and absolute confidence.
It makes its world premiere on the Ducati Superleggera V4 Centenario, creating a new industry segment.
