Specs At A Glance

Good To Know

Q: How do I know if the left side is the correct orientation for my scooter? A: The left master cylinder mounts on the left side of the handlebar and controls the front brake lever on most GY6 setups. Confirm which side your original unit sits on before ordering.

Q: Does this unit come with brake fluid or a brake line? A: No, brake fluid and lines are not included with the master cylinder. Bleed the system with fresh DOT fluid after installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
