Razor Left Brake Lever w/ Motor Cut-Off Wire

Safety Integrated: Left Brake Lever with Cut-Off Switch

Ensure reliable stopping power and electrical safety with this Universal Parts Wired Left Brake Handle. Designed specifically for electric scooters and go-karts, this lever features a built-in micro-switch and a 48-inch wiring harness. When the lever is squeezed, it instantly signals the controller to cut power to the motor—a vital safety feature that prevents the motor from fighting the brakes and protects your electrical system from overheating.

Technical Performance Features

• Integrated Motor Cut-Off: The pre-installed 2-wire lead connects directly to your controller to disable the throttle during braking, ensuring shorter stopping distances and reduced motor wear.
• 48-Inch Extended Wire: The generous cable length provides ample reach for high-bar scooters and long-frame go-karts, allowing for clean routing through the chassis.
• Adjustable 22mm Perch: Features a standard 22mm inner diameter that can be adjusted down for a snug, slip-free fit on all common 7/8-inch handlebars.
• Ergonomic Alloy Blade: The lever blade is contoured for comfortable two-finger or four-finger braking, providing consistent leverage and a crisp mechanical feel.

Mechanic's Note: If your electric motor won't turn on even with a full battery, a faulty brake switch is a common culprit. If the internal switch "sticks," the controller thinks the brakes are on and will lock out the throttle. Replacing this handle is the fastest way to restore throttle functionality and safety.
