Engineered exclusively for racing use, this 100mm kit pairs a rigidly machined monoblock aluminium body with four titanium pistons to deliver the kind of fade-free, perfectly progressive feel that no road-spec caliper can match.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFour titanium pistons in a staggered 32 mm \/ 36 mm configuration for powerful, linear braking force throughout the full lever travel\u003c\/li\u003e\n\u003cli\u003eMonoblock aluminium construction — milled from a single billet and hard-anodised — eliminates caliper flex under extreme braking loads\u003c\/li\u003e\n\u003cli\u003eOptimised thermal management channels heat away from the pistons and fluid, dramatically reducing fade during long, heavy braking zones\u003c\/li\u003e\n\u003cli\u003eCompatible with both DOT 4 and DOT 5.1 brake fluid, giving teams flexibility when bleeding at the circuit\u003c\/li\u003e\n\u003cli\u003e30 mm offset and 100 mm fork-mount bolt spacing covers a wide spread of European and Japanese supersport platforms\u003c\/li\u003e\n\u003cli\u003eMaximum disc thickness of 7.25 mm keeps the kit compatible with the majority of racing-spec brake discs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTrack-Focused Engineering\u003c\/h2\u003e\u003cp\u003eThe GP4-RR designation puts this caliper firmly in Brembo's competition hierarchy. The monoblock body is not simply stiffer than a two-piece unit — it is a fundamentally different structural approach that removes the bolted joint at the highest stress point of the caliper, translating directly into more consistent lever feel and greater rider confidence at the limit. The hard-anodised finish protects the aluminium from the combined assault of brake dust, heat cycles and the aggressive cleaning chemicals used in a race paddock environment.\u003c\/p\u003e\u003ch3\u003eTitanium Pistons\u003c\/h3\u003e\u003cp\u003eTitanium's low thermal conductivity means significantly less heat migration from the disc and pad compound into the brake fluid compared with steel or aluminium pistons. For racing applications this is not a marginal gain — it is a primary safeguard against vapour lock during sustained high-speed braking. The 32\/36 mm stagger produces a progressive bite characteristic that experienced riders can modulate with precision, even mid-corner.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis kit is designed for forks with a 100 mm bolt spacing and fits a broad range of European and Japanese supersport machines, including:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAprilia RSV4, RSV4 R, RSV4 RR, RSV4 RF, RSV4 1100, RSV4 1100 Factory, RS 660\u003c\/li\u003e\n\u003cli\u003eDucati Panigale 848, 899, 959, 1199, 1199 S, 1199 R, 1299, 1299 S\u003c\/li\u003e\n\u003cli\u003eBMW S1000RR, HP4, HP4R, M1000RR\u003c\/li\u003e\n\u003cli\u003eKTM RC8 1190, 1290 Super Duke R, RC 390\u003c\/li\u003e\n\u003cli\u003eKawasaki ZX-10R, ZX-10RR (from 2016 onward)\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR-R SC82 (2020 onward), CBR 1000 RR, CBR 600 RR\u003c\/li\u003e\n\u003cli\u003eYamaha R1, R1M, R6, R7\u003c\/li\u003e\n\u003cli\u003eTriumph Daytona 675, Daytona 675 R, Daytona 765, Street Triple 765 R, Street Triple 765 RS\u003c\/li\u003e\n\u003cli\u003eMV Agusta F3, F4\u003c\/li\u003e\n\u003cli\u003eSuzuki GSX-R 600, GSX-R 750, GSX-R 1000\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAlways verify fork bolt spacing before fitting.
