Technical Performance Features

• Ergonomic Alloy Lever: The master cylinder features a high-strength aluminum alloy lever designed for two-finger operation, providing effortless modulation and reduced hand fatigue.
• Standard 51.5mm Mount: The caliper is built to the industry-standard 51.5mm bolt-hole spacing, ensuring a drop-in fit for most "Super" and "Mini" pocket bike forks.

Mechanic's Note: Most entry-level pocket bikes use mechanical calipers that fade under heat. Performance Benefit: Switching to a hydraulic system like this one provides a "linear" braking feel that doesn't stretch or go soft during long sessions. Pro Tip: Before mounting, verify your Caliper Bolt Spacing—if your fork uses a 43mm or 60mm mount, you will need a Caliper Adapter Bracket to complete the install!
