Brembo RCS 19 Master Cylinder for 1" Handlebars
Upgrade your front braking system with the Brembo RCS 19 Master Cylinder, designed for high-performance dual-disc applications using 1" handlebars. Featuring a 19mm piston and Brembo's adjustable 18/20mm RCS leverage system, this radial master cylinder allows riders to fine-tune brake feel and response for greater control at the lever.
Constructed from forged aluminum with a hard-anodized finish, the RCS 19 combines strength, precise braking performance, and premium Brembo engineering. The kit includes banjo bolts for both single-line and dual-line brake hose configurations, crush washers, and the supplied microswitch. A Harley-Davidson-specific brake light switch solution must be purchased separately where required.
