Description

RDR vented performance clutch drum (clutch bell) for GY6 125cc/150cc scooters, ATVs, and Honda Navi 110 — 19-spline hub, 125mm inner diameter, multi-window vented outer chassis for heat dissipation, and a friction-enhanced inner wall that eliminates clutch slip, shudder, and thermal glazing. Precision balanced. Direct replacement or performance upgrade over stock. SKU: 169-497 | MPN: RL-1103.

  • Precision computer-balanced during manufacturing — eliminates high-RPM vibration
  • Lightweight design — reduces rotating mass for faster throttle response vs. stock casting
  • 19-spline hub — direct drop-in for GY6 125/150cc QMI152/QMJ152 and QMI157/QMJ157 platforms
