Genuine GY6 QMB Nitrogen-Charged Adjustable Rear Shock

Adjustable Rear Shock with Nitrogen Charge for Genuine Scooters

This adjustable rear shock is an upgrade for Genuine Buddy scooters from 50cc through 170cc, and for most 139QMB 50cc and GY6 125/150cc platforms. It is built for demanding riders and uses a nitrogen gas charge to keep performance steady under heavy use. The settings can be adjusted so you can tune the ride to your liking.

Nitrogen Gas Charged Build

Nitrogen gas is used in this rear shock to reduce heat build-up and limit expansion. That helps it perform dependably during long or intense rides. The design supports consistent shock behavior, which contributes to a smoother ride.

Adjustable Damping for Personal Comfort

A built-in 25-position damping adjuster lets you change how firm the shock feels. Turning it clockwise makes the shock stiffer, and turning it counterclockwise makes it softer. You can set it to suit your own riding style and preferences.
