Brembo 19RCS Clutch Master Cylinder

The Brembo 19RCS Clutch Master Cylinder is engineered for riders who want maximum control and adjustability from their hydraulic clutch system. Built with Brembo’s patented Ratio Click System, the 19RCS allows you to switch between 18mm and 20mm leverage ratios, letting you fine-tune lever feel for different conditions.

Crafted from forged aluminum with an anodized finish, the 19RCS combines lightweight strength with proven Brembo performance. Its folding lever design provides extra protection in the event of a crash, making it equally at home on the street or at the track.

Key Highlights:

• Radial master cylinder for precise clutch control
• Adjustable ratio (18/20) for customizable lever feel
• Forged aluminum body with anodized finish
• Folding lever minimizes crash damage
• Fits 7/8” (22mm) handlebars — standard on most European & Japanese motorcycles
• Optimized for superbikes with larger hydraulic clutch systems

Included in the Box:

• Brembo 19RCS Clutch Master Cylinder
• Double banjo bolt
• New crush washers
• Brembo authenticity/warranty card

Notes

• A Brembo reservoir kit is required for installation and is sold separately.
• For Ducati models, a clutch sensor switch kit may be required to retain OEM functions (sold separately).
• Riders choosing between the 16RCS and 19RCS should note: the 19RCS provides a firmer, more direct lever feel, ideal for larger-displacement superbikes and aggressive riding. The 16RCS offers a lighter pull and smoother modulation, reducing hand fatigue on the street or during long sessions.
