125mm Clutch Bell for Buddy, GY6 & Honda Navi

125mm Clutch Bell Compatible with Genuine Buddy, GY6, and Honda Navi Scooters

This lightweight clutch bell is built to sharpen throttle response on Genuine Buddy, GY6, and Honda Navi scooters. With less rotating mass, the engine can climb through its rev range more quickly, which gives the ride a livelier feel. It is listed among our Genuine Buddy scooter parts, and it plays a useful role when you want your scooter to perform well under demanding conditions.

Light Weight with Ventilated Housing

Reduced weight in this clutch bell helps the scooter accelerate more readily and supports smoother engine output. The housing has large openings and perimeter holes that let heat escape and push clutch debris outward. This matters most on longer or more aggressive rides, where the clutch can stay cooler and run more evenly.

Durable Build for Better Engagement

The clutch bell is made from heavy-duty forged steel, chosen to handle high temperatures and sustained strain. Its inner drum has a light texture that grips the clutch shoes more effectively, which can reduce glazing and help limit shudder when pulling away. The design suits a wide range of riding conditions.
