Developed from Brembo's MotoGP programme and refined for demanding road and trackday use, it delivers a level of feel and power that standard OEM units simply cannot match.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStreet-legal with ABE approval and KBA number — full type approval for road use across Germany and the EU, with no registration complications.\u003c\/li\u003e\n\u003cli\u003eRCS (Ratio Control System) — the lever ratio is rider-adjustable on the fly: 19x18 (red marking) for progressive, soft modulation; 19x20 (black marking) for a more direct, immediate bite.

Selecting 19x18 increases the mechanical advantage slightly, producing a longer, softer lever stroke that suits wet roads, cold tyres, or riders who prefer to trail-brake progressively into corners. Switching to 19x20 shortens the effective stroke, delivering a sharper, more immediate response favoured on circuit where maximum initial bite matters. The M10 x 1.0 brake line port is the standard radial master cylinder thread used across the majority of modern supersport and superbike platforms, making hose routing straightforward.\u003c\/p\u003e\u003ch2\u003eConstruction and Safety\u003c\/h2\u003e\u003cp\u003eThe pump body is forged rather than cast — a critical distinction that produces a denser grain structure, higher fatigue resistance, and a noticeably stiffer feel at the lever. CNC machining ensures bore tolerances are held to racing specifications, and the hard-anodised finish protects the aluminium from brake fluid splash, stone chips, and UV degradation. The folding lever pivot is a genuine safety feature: at 262 g the entire assembly is lighter than many OEM cast units, yet the folding design means a parking-speed fall is far less likely to leave you without a brake lever. This combination of certified safety compliance, precision engineering, and adjustability is why the RCS 19 x 18-20 is trusted by riders who use the same machine on the road Monday and the track at the weekend.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Brembo RCS 19 x 18-20 is a universal radial master cylinder fitting the vast majority of modern supersport and superbike models equipped with radial brake caliper mounts.
