Performance Throttle Cable, 76", GY6 150cc, 50cc (139QMB)

Performance Throttle Cable for GY6 150cc and 50cc Scooters

This performance throttle cable is built to sharpen control on GY6-style scooters, and it is intended for 125cc, 150cc, and QMB139 50cc models. It measures 76 inches end to end and is designed to remove throttle sticking while helping the engine respond more quickly. Compared with standard factory cables, its low-friction construction gives a smoother twist. If you are browsing GY6 50cc scooter parts, this is one option to consider.

Improved Throttle Control

The 76-inch length suits scooters with longer frames and custom layouts such as the Ruckus or Zuma, particularly where aftermarket handlebars need the extra run. The PTFE-lined housing reduces friction, so the throttle pulls more lightly, which may ease hand strain on longer rides.

Corrosion-Resistant Ends

Both ends are made to resist corrosion, so they hold firmly at the throttle housing and the carburetor. The 90-degree elbow at the handlebar end helps the cable route neatly and reduces the chance of kinking near the master cylinder. Together, these features support consistent throttle action.
