Brembo Radial GP4-MS CNC Monoblock Brake Caliper Kit 100mm Topology-Optimised 220D60050

Born from the pitlane and shaped by topology optimisation, the Brembo GP4-MS Radial Monoblock brake caliper kit is the definitive expression of MotoGP braking technology for the road and track. Its hand-painted red Brembo logo, nickel-plated finish and sculpted cooling fins are not mere aesthetics — they are the signature of a caliper developed to the same philosophy that wins world championships. Part number 220D60050, supplied as a complete left-and-right kit with pads and thermotapes.

Key Features

• Radial CNC P4 30 monoblock construction — milled from a single billet for absolute torsional rigidity and zero flex under maximum braking loads
• Topology-optimised architecture reduces mass to approximately 670 g per caliper (without pads) while reinforcing every load path that matters
• Characteristic cooling fins and nickel-plated surface deliver class-leading thermal management, protecting fluid and seal integrity on long track sessions
• Four pistons at 30 mm diameter each, with dual sealing for street-legal reliability and progressive pad return
• 100 mm radial mounting pitch, 30 mm offset — direct replacement for OE M50, Stylema and M4 calipers across a wide range of performance bikes
• High Performance Sinter TT brake pads (part number 07BB3793) included as standard — no compromise from the first lap
• Compatible with DOT 4 and DOT 5.1 brake fluid

Design, Finish and Heritage

The GP4-MS occupies a unique position in Brembo's catalogue: it carries the structural DNA of full-factory MotoGP hardware in a package that can be legally bolted to a road-registered machine. The monoblock body is CNC-machined to exacting tolerances, then nickel-plated for corrosion resistance and the precise tactile finish you expect from Italian race engineering. The cooling fins are not decorative — they are integral to the caliper's heat-shedding strategy, channelling airflow to the pad and piston interface during sustained hard braking.

Where many aftermarket calipers are simply heavier OE units rebranded in red, the GP4-MS is topology-optimised: material is removed computationally from every zone that does not carry structural load, leaving a caliper that is stiffer, lighter and more consistent in feel than conventional casting-based designs. The hand-applied red Brembo script is applied after machining and plating — a deliberate finishing step that distinguishes genuine Italian-origin Brembo racing components from grey-market copies.

Performance on Road and Track

At 100 mm radial pitch with 30 mm offset, the GP4-MS slots directly in place of OE Brembo M50, Stylema and M4 calipers without bracket modification on supported models. The four-piston layout and dual-seal system give the caliper a progressive initial bite that suits both track-day use — where consistent modulation lap after lap is critical — and road riding, where variable conditions demand a broad power band. The included Sinter TT sintered pads (07BB3793) are bedded in quickly and maintain stable friction coefficients from cold, making the kit genuinely usable from the moment installation is complete.

This is a racing product: no type-approval certificate (TÜV Gutachten) is issued, and installation on public roads is the rider's responsibility under local regulations. Replacement parts are available — for example, dust cap for bleed nipple, part number 05150210. The kit is supplied direct from Brembo Italy; it is not a re-import or grey-market product.
