Bearing Spring Seat for GY6 50cc (139QMB), Honda Dio, Elite 50

Bearing Spring Seat for GY6 50cc Engines and Honda Dio/Elite 50

The Bearing Spring Seat is a modification made for GY6 50cc engines, covering the Honda Dio and Elite 50. It targets torque spring binding inside CVT systems, a problem that can cause uneven shifting and slow pickup. Among the GY6 50cc scooter parts available, this one aims to make operation smoother and throttle response more consistent through its ball-bearing track.

Performance Benefits

The part uses a needle/ball bearing sandwich plate to reduce friction between the torque spring and the clutch pulleys. Letting the spring turn freely helps back-shifting and acceleration. Riders may notice better throttle response, particularly when it is used with a 1000 or 1500 RPM torque spring. A suitable CVT grease is recommended during installation.

Construction Details

The spring seat has high-tensile steel races for durability. It suits clutches 107mm or smaller and works with both OEM and aftermarket torque springs, making it a practical option for riders wanting to improve how their scooter performs.
