Direct answer: Measure motorcycle brake caliper mounting distance between the centers of the mounting holes only after identifying whether the mount is axial or radial. Bolt spacing alone is not fitment proof. Also verify the measurement datum, offset, rotor diameter and thickness, pad sweep, hose connection, hydraulic match, hardware, clearance, and installation instructions. A brake caliper can look close to the original part and still be unsuitable. The mounting holes may be spaced differently.
- Identify whether the mount is axial or radial before measuring
- Measure the distance between the centers of the mounting holes
- Verify the measurement datum and offset
- Check rotor diameter and thickness for compatibility
- Inspect pad sweep area on the rotor
- Check hose connection type and hydraulic match
- Review hardware, clearance, and installation instructions
- A caliper that looks similar may still be unsuitable due to mounting hole spacing

Frequently Asked Questions
What is the key measurement for caliper mounting?The key measurement is the distance between the centers of the mounting holes, measured after identifying whether the mount is axial or radial.
What types of caliper mounts are there?There are two main types: axial mount and radial mount. The measurement method differs for each.
What else should be checked besides bolt spacing?Besides bolt spacing, verify offset, rotor diameter and thickness, pad sweep, hose connection, hydraulic match, hardware, clearance, and installation instructions.
