Key Fitment and Compatibility

This kit is designed to fit a broad set of minibike models and is clearly labeled as a rear caliper, disc brake system—not a front caliper and not a drum brake. It works with bikes that use a 7/8-inch (22 mm) handlebar and a rear disc brake configuration. Popular compatibility includes models from Coleman Baja, Motovox MBX10/MBX11, Monster Moto Mega Moto family, Predator variants, and related FR* GMB100 minibikes. Always verify that your current braking setup aligns with a rear disc brake caliper before purchasing.
