Built for riders who refuse any compromise at the limit, this left-hand caliper delivers the combination of structural rigidity, titanium piston heat management and hydraulic precision that circuit racing demands.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCNC-machined monoblock construction eliminates flex for consistent, repeatable stopping power under sustained race loads\u003c\/li\u003e\n\u003cli\u003eFour titanium pistons — 2x 34 mm and 2x 38 mm — minimise heat transfer to the brake fluid for fade-free performance session after session\u003c\/li\u003e\n\u003cli\u003e30 mm pad contact track maximises friction area and braking force at maximum deceleration\u003c\/li\u003e\n\u003cli\u003e22.5 mm offset ensures precise disc alignment and correct pad presentation across a wide range of race machinery\u003c\/li\u003e\n\u003cli\u003eNickel-plated exterior resists corrosion and the visual wear of track environments while preserving the caliper's structural integrity over a long service life\u003c\/li\u003e\n\u003cli\u003eRace-proven across the highest levels of international competition — the same specification trusted by WorldSBK and Moto2 teams worldwide\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eRace-Grade Construction\u003c\/h2\u003e\u003cp\u003eThe monoblock design is not merely a marketing claim — it is the engineering foundation behind every elite Brembo Racing caliper. Machined from a single billet, the P4 34\/38 has no join line across the bridge, which translates directly into a stiffer housing and a more direct pedal or lever feel. The central bridge provides an additional stiffening axis, ensuring that caliper body distortion under peak braking load remains negligible, a quality that becomes decisive when the difference between a safe late-braking point and a crash is measured in centimetres.\u003c\/p\u003e\u003cp\u003eThe titanium pistons are a safety-critical upgrade over steel alternatives. Titanium's low thermal conductivity keeps heat inside the disc and pad interface rather than migrating into the hydraulic circuit. Sustained high-temperature braking — precisely the condition found in long WorldSBK or BSB races — is where this caliper proves its safety credentials most clearly.\u003c\/p\u003e\u003ch2\u003ePerformance on Circuit\u003c\/h2\u003e\u003cp\u003eCaliper stiffness is the primary determinant of modulation quality, and the CNC monoblock P4 34\/38 delivers a lever feel that allows riders to place braking markers with confidence lap after lap. The nickel-plate finish protects the aluminium body without adding unnecessary mass, keeping unsprung weight as low as possible — a tangible benefit on the front axle where gyroscopic and inertial forces are most significant.\u003c\/p\u003e\u003ch2\u003eImportant Safety Notice\u003c\/h2\u003e\u003cp\u003eThis caliper is manufactured exclusively for closed-circuit competition use. It is not approved or intended for road use. Fitment requires a fork with a 108 mm mounting hole spacing — verify your fork specification before ordering. Brake pads are not included and must be ordered separately.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe XA3J7F0 is compatible with a wide range of race and road-homologated motorcycles equipped with forks carrying a 108 mm caliper mount spacing, including models from Aprilia, BMW, Ducati, Honda, Kawasaki, KTM, MV Agusta, Suzuki, Triumph and Yamaha.
