Brembo 17x18 Billet Radial Brake Master Cylinder - XA7G755

Achieve ultimate braking precision with the Brembo 17x18 Billet Radial Master Cylinder (XA7G755). Race-proven performance, folding lever, and zero-compromise feel.

The Brembo 17x18 Billet Radial Front Brake Master Cylinder (Part No. XA7G755) is a pinnacle of racing technology, engineered for riders who demand the absolute best in braking performance and feel. This master cylinder is precision-machined from a solid block of aluminum (Billet) using advanced CNC methods, resulting in a housing that is lighter, stronger, and more consistent than cast counterparts. The 17mm piston diameter is optimally paired with the 18mm pivot distance (ratio), providing a braking action that is responsive, direct, and offers a firm, progressive feel, making it ideal for bikes with dual front calipers. The radial design ensures that the braking force is applied in line with the handlebar, minimizing flex and maximizing efficiency. This specific EVO version features a long, folding lever that is designed to pivot upwards in the event of a crash, significantly reducing the chance of breakage and allowing the rider to continue. Sold without a reservoir for a custom race setup, the Brembo 17x18 is the ultimate upgrade for track day enthusiasts and professional racers seeking uncompromising control and a significant competitive advantage.

Best Uses

1. Track Day Enthusiasts: Provides the necessary power and modulation for high-speed track riding and aggressive braking zones.
2. Sportbike Racing (Supersport/Superbike): A critical component for professional and amateur racers seeking a competitive edge in control and consistency.
3. High-Performance Street Riding: An excellent upgrade for street riders with modified, high-power sportbikes who want improved feel and fade resistance.
4. Motorcycles with Dual Front Calipers: Optimally sized for the demanding fluid displacement required by dual-disc braking systems.

Features

1. Billet Aluminum Construction: Precision-machined from a solid block of high-grade aluminum, offering superior strength, reduced weight, and zero internal porosity compared to standard cast cylinders.
2. 17x18 Ratio Configuration: Features a $17\text{mm}$ piston and $18\text{mm}$ pivot distance, delivering a potent combination of braking power and a firm, direct lever feel.
3. Radial Design: Positions the piston perpendicular to the handlebar, ensuring maximum leverage efficiency and a consistent, linear transfer of force to the calipers.
4. EVO Long Folding Lever: The crash-resistant lever is designed to fold away upon impact, protecting the master cylinder from damage and minimizing the risk of a DNF (Did Not Finish).
5. Race-Ready Specifications: Designed and utilized by top-tier racing teams, ensuring the highest standards of reliability, performance, and durability under extreme conditions.

Benefits

1. Enhanced Braking Consistency: The billet construction and radial design maintain consistent lever feel and performance, minimizing "pump-up" and fade over long, hard braking sessions.
2. Superior Control and Feedback: Offers the rider a highly precise, tactile connection to the front wheel, allowing for minute adjustments and confident threshold braking.
3. Increased Crash Protection: The long folding lever significantly reduces the risk of expensive master cylinder housing damage in a tip-over or low-side incident.
4. Immediate Performance Upgrade: Provides a noticeable and immediate improvement in braking response and power modulation over most OEM master cylinders.
5. Reduced Weight (Unsprung Mass): Billet construction is inherently lighter than standard OEM cast units, contributing to overall weight savings on the motorcycle.
