When replacing the rear caliper with a GALE SPEED or Brembo opposed 2-piston caliper (φ32, φ34), depending on the ratio, the brake pedal stroke may become too short, making it difficult to control. The GALE SPEED rear master cylinder has a piston diameter of φ12 and is designed to match the lever ratio of typical racing footpegs. This achieves a delicate and controllable rear brake system. ■Specifications Type: Mounting pitch 40mm\/49mm\/Rod end M6 Color: Brown Piston size: φ12 Compatible caliper: Piston diameter φ32\/φ34 opposed 2-piston Bolt pitch: P1.00 Fluid tank: Separate type Fluid nipple (included): φ6\/φ7.3 (90°) Return spring (included): Standard\/Hard ■Notes *Images are for illustration purposes only.
