To ensure correct fitment and avoid compatibility issues, it is crucial to verify the specifications of your existing brake disc before ordering. Different production years or versions of the same scooter model may sometimes use slightly different parts.

Before purchasing, please compare the following with your current brake disc:

• Diameter: Confirm it is 140 mm.
• Mounting Holes: Ensure your hub uses a 6-hole bolt pattern.
• Physical Dimensions: Check the overall shape, mounting points, and central bore dimensions (e.g., 23 mm inner diameter, 45 mm bolt circle diameter, 39 mm distance from center to bolt hole center) against the provided image.
• Thickness: Verify the disc thickness is approximately 1.8 mm.

If you are uncertain about compatibility, we recommend comparing the markings or technical data on your original part with the details provided. Professional installation is recommended for all braking system components to ensure safety and proper function.

Maintenance and Safety

Regular inspection of your brake discs for wear, warping, or damage is essential for safe riding. Replace the brake disc if you notice significant scoring, uneven wear, or if its thickness falls below the manufacturer's recommended minimum (if available). After installing a new brake disc, it is important to perform a proper "bedding-in" procedure. This involves a series of gentle stops followed by progressively harder stops to allow the brake pads and disc to conform to each other, optimising braking performance and longevity.
