Description
This Blue Line Left Handlebar Switch & Lever Assembly (SKU 0800-4001) is a direct replacement left-side control for many 139QMB (QMB139) 50cc scooters, the Chinese GY6 50cc platform based on Honda's GY6 design. It fits the common left switch layout used across a wide range of these scooters, including Chicago Scooter Company models like the go., go MAX, Pug 50, Nitro Sport 50, and Bella Classic 50.
