At DMG Motorsports, we present the Brembo RCS 17mm Upgrade Brake Master Cylinder — a race-proven radial master cylinder built for riders who demand sharper feedback and total control over their braking feel. Featuring a large 17mm piston, the 17RCS master cylinder issues better feedback than the 19RCS while still providing excellent stopping power, making it the go-to upgrade for dual-caliper, four-piston braking systems on today's high-performance sportbikes. Whether you're chasing lap times or simply want a more connected feel at the lever, this Brembo RCS unit lets you dial in the exact bite point and modulation you need to ride with confidence.

Built around Brembo's patented RCS (Ratio Click System), this master cylinder puts adjustability right at your fingertips. With nothing more than a simple screwdriver, you can switch between a sharper, more aggressive lever feel or a softer, more progressive response to match your riding style, track conditions, or brake setup. The forged aluminum alloy body is precision machined for the tight tolerances demanded by racing applications, and Brembo's engineering pedigree from World Superbike and MotoGP is built into every component.

• 17mm piston delivers strong stopping power with enhanced lever feedback compared to larger-bore master cylinders
