Description

This RDLN Racing Clutch Bell is a lightweight, vented 107mm clutch drum for GY6 139QMB / 139QMA 50cc engines and their 80cc to 100cc big-bore builds. Its grooved inner drive face grips the clutch shoes to cut slippage and prevent glazing. The vented design lowers rotating weight for snappier acceleration and helps shed heat so your clutch pads last longer.

This product is intended for off-road use only. This product is not intended for use on public roads or land.

Key Features

  • Grooved drive face: Sheds clutch dust, reduces slippage, and prevents glazing under load.
  • Vented design: 10 cutouts increase airflow to keep the transmission cooler.
  • Lightweight: Lower rotational mass for quicker throttle response and higher RPM.
  • Racing red finish: Bold red with the RDLN High Performance Parts logo on the hub.
