Brembo 17×18 XR0 Brake Master Cylinder – Billet Racing Radial
The Brembo 17×18 XR0 Brake Master Cylinder is a race-developed upgrade built for riders who demand maximum control and precision on the track. CNC-machined from billet aluminum with a radial design, the 17×18 XR0 is engineered for consistent braking performance and superior lever modulation under extreme riding conditions.
With its 17 mm piston and 18 mm lever ratio, this master cylinder provides a smoother, more progressive lever feel compared to the 19 mm XR0 options, making it the preferred choice for superbikes equipped with 30 mm piston calipers such as the Brembo Stylema or GP4-MS. The folding long lever design minimizes crash damage and ensures reliability during competition use.
Key Highlights:
- CNC billet master cylinder for ultimate performance and rigidity
- 17 mm piston with 18 mm lever ratio for refined, progressive lever feel
- Folding long lever minimizes crash damage
- Race-only design; no brake light switch included
- Fits 7/8” (22mm) handlebars — standard on most sportbikes
- Optimized for 1000cc superbikes with dual front discs (32–34mm caliper pistons)
Included in the Box:
- Brembo 17×18 XR0 Master Cylinder (billet, with folding long lever)
- Double banjo bolt

Notes
- A Brembo reservoir kit is required for proper installation and is sold separately.
- For street applications, a brake light switch can be added using an optional banjo bolt with integrated switch (not included).
- Riders choosing between the XR0 lineup should note: the 17×18 offers smoother modulation and lighter lever effort, while the 19×18 and 19×20 provide a firmer, sharper response.
