NCY Weight-Adjustable Racing Clutch - GY6 125/150cc

This NCY weight-adjustable clutch lets you tailor how your GY6 125/150cc scooter launches without removing the clutch springs. Removable weights in all three clutch arms give you a quick way to choose earlier engagement or let the engine rev higher before the clutch takes hold.

Key Features

• Quick engagement tuning: Install or remove the shoe weights without removing the clutch springs.
• Weights installed: Heavier clutch shoes overcome spring force at a lower RPM, producing earlier engagement.
• Weights removed: Lighter clutch shoes require a higher RPM to overcome spring force, producing later engagement.
• Three-shoe design: Uses three friction pads measuring 48 × 22mm each.
• Open inner layout: Constructed without an inner brace.
• Made in Taiwan: NCY aftermarket performance clutch.

Compatibility

For compatible GY6 125/150cc scooter CVT applications. Match the clutch, bell and rear-pulley mounting configuration to your existing setup before installation.

Tuning and Installation

Always install all three weights or remove all three weights together. Do not mix weighted and unweighted shoes, as this can unbalance the clutch. Engagement RPM depends on the spring setup and overall CVT configuration; removing weights raises engagement RPM, while installing them lowers it.
