NCY Rear Pulley Assembly — Honda Ruckus | GY6 50 & DIO Clutch Compatible

NCY Rear Pulley Assembly for Honda Ruckus

Unlock full CVT flexibility on your Honda Ruckus with the NCY Rear Pulley Assembly. Designed to accept any GY6 50 (QMB139) or DIO clutch and bell, this pulley assembly opens the door to a wide range of performance clutch upgrades — while remaining fully compatible with your stock contra spring for a straightforward bolt-on install.

Why Upgrade to the NCY Rear Pulley?

The stock Ruckus rear pulley limits your clutch options to Honda-specific components. The NCY assembly breaks that restriction, letting you run popular GY6 and DIO clutch systems for better engagement, improved top speed, and a more tunable CVT setup. Whether you’re building a mild street scooter or a full performance Ruckus, this is the foundation piece.
